Effective grain orientation on the substructure development of 304 stainless steel and NA-30% fe

This data is the result of an investigation into the effect of grain orientation on the substructure development of 304 stainless steel and a Ni-30wt.%Fe alloy. Both alloys have been used as model alloys to study the high temperature deformation of austenite. The development of the dislocation substructure as a function of strain, temperature and grain orientation was investigated using a combination of electron backscatterd diffraction (EBSD) and transmission electron microscopy (TEM).

Drivers, impediments and manifestations of brand orientation in museums : an international museum study

Purpose - While the body of work exploring brand orientation has grown, there has been a general failure to build on extant research and generate a holistic conceptualization of brand orientation. This paper aims to develop a model of the key drivers, impediments and manifestations of brand orientation in a museum context.

Design/methodology/approach - A collective case study design was used, consisting of key informant interviews using a semi-structured interview protocol and analysis of institutional documents and observational research. Interviews took place with well-known museums across three countries: the United Kingdom, the United States of America and Australia. This paper demonstrates the richness of qualitative case studies as a method of theory building and as a precursor to further empirical research.

Findings - The case study findings reveal both a philosophical and behavioral aspect of brand orientation. Thus, six attributes are presented that include brand orientation as an organizational culture and compass for decision-making and four brand behaviors (distinctiveness, functionality, augmentation and symbolism). The conceptual model also depicts the critical antecedents to brand orientation in a museum context.

Research limitations/implications - This study provides a foundation for future brand research by offering a holistic conceptualization of brand orientation and identifying the primary antecedents in a museum context. Future research may wish to empirically establish a valid and reliable scale of brand orientation and examine its explanatory potential. Future research may also consider other contexts to provide further insight into the drivers and inhibitors of brand orientation.

Practical implications - If organizations seek to establish a strong brand orientation they must devote resources to establishing the brand as a dominant organizational philosophy that guides decision-making. In addition, brand oriented organizations must establish the brand as a distinctive asset that communicates relevance and accessibility and invest in augmenting initiatives that enable the organization to connect with customers on a personal and emotional level.

Originality/value - Using an exploratory method we are able to reconcile a number of approaches to brand orientation and provide a conceptualization that incorporates the philosophical and behavioral approaches to business orientations. Museums face substantial resource constraints, competing needs of multiple stakeholders and increasing market turbulence. If museums can achieve such significant organizational change then the sector presents an interesting exemplar for many other non-profit organizations.

Effects of crystallographic orientation on corrosion behavior of magnesium single crystals

The corrosion behavior of magnesium single crystals with various crystallographic orientations was examined in this study. To identify the effects of surface orientation on the corrosion behavior in a systematic manner, single-crystal specimens with ten different rotation angles of the plane normal from the [0001] direction to the [1010] direction at intervals of 10° were prepared and subjected to potentiodynamic polarization and potentiostatic tests as well as electrochemical impedance spectroscopy (EIS) measurements in 3.5 wt.% NaCl solution. Potentiodynamic polarization results showed that the pitting potential (E _pit) first decreased from −1.57 V _SCE to −1.64 V _SCE with an increase in the rotation angle from 0° to 40°, and then increased to −1.60 V _SCE with a further increase in the rotation angle to 90°. The results obtained from potentiostatic tests are also in agreement with the trend in potentiodynamic polarization tests as a function of rotation angle. A similar trend was also observed for the depressed semicircle and the total resistances in the EIS measurements due to the facile formation of MgO and Mg(OH)₂ passive films on the magnesium surface. In addition, the amount of chloride in the passive film was found first to increase with an increase in rotation angle from 0° to 40°, then decrease with a further increase in rotation angle, indicating that the tendency to form a more protective passive film increased for rotation angle near 0° [the (0001) plane] or 90° [the (1010) plane].

Orientation relationship, texture and microstructure in electromagnetic processed materials (EPM)

In this work, some of our recent results in microstructure, texture and orientation relationship resulting from the application of an external high magnetic field during diffusional and non-diffusional phase transformation in both steel and functional metallic materials have been summarized. A 12-T magnetic field was applied to the diffusional decomposition of austenite in 0.81C-Fe alloy and martensitic transformation of a Ni-Mn-Ga magnetic shape memory alloy. For the 0.81C-Fe alloy, it was found that the magnetic field induces the formation of proeutectoid ferrite and slightly enhances the <001> fiber component in ferrite in the transverse field direction. The magnetic dipolar interaction between Fe atoms in the transverse field direction accounts for this phenomenon. The magnetic field favors the formation of pearlite with Pitsch-Petch 2 (P-P 2) and Isaichev (IS) orientation relationships (OR) between the lamellar ferrite and cementite. For the Ni-Mn-Ga magnetic shape memory alloy, the magnetic field makes the martensite lamellas to grow in some specific directions with their c-axes [001] orientated to the field direction and transverse field direction.

The relationship between knowledge management strategic orientation and business strategic orientation among SMEs

Little is known about how Small and Medium Sized Enterprises (SMEs) practise Knowledge Management (KM) from both a theoretical and empirical perspective. Some research has been conducted in this field but from a western cultural perspective. Research on KM and SMEs in developing countries such as Saudi Arabia is limited. The research reported in this paper investigated KM strategic orientations and business strategic orientations in Saudi Arabian SMEs. The research involved the development of a theoretical framework relating to KM strategies and business strategies. Three KM strategies were proposed: aggressive, conservative and balanced and were linked to Miles and Snow’s typology: prospectors, defenders and analysers respectively. The empirical research involved a survey of Saudi Arabian SMEs. A total of 143 SMEs, participated in the survey. The results indicate that the proposed classifications and relationships between KM strategic dimensions were valid. It further shows that there was an association between business strategy and KM strategy exists and the proposed linkage between: prospectors and aggressive KM strategy, defenders and conservative KM strategy and analysers and balanced KM strategy were mostly confirmed but with some inconsistency regarding knowledge breadth dimensions.

Effects of informal institutions on the performance of microenterprises in the Phillipines : the mediating role of entrepreneurial orientation

The study investigates the effects of informal institutions and entrepreneurial orientation on the performance of microenterprises at the subnational level within a developing country context. Using structural equation modeling based on a large-scale survey of 735 microenterprises in the Philippines, it is found that informal institutional factors and entrepreneurial orientation are associated with firm performance. However, further analysis reveals a strong mediating role of entrepreneurial orientation on the informal institutions-firm performance relationships. This finding is novel and adds to our understanding of the mechanism through which informal institutions affect firm performance, particularly for microenterprises in developing countries.

Retail brand orientation, positional advantage and organisational performance

This study adopts a resource-based view of branding referred to as brand orientation. Despite the importance of branding in retail, relatively little empirical research has been conducted to understand the degree to which retailers can be considered brand oriented. The purpose of the present research is to establish a conceptualisation of brand orientation that is applicable in a retail context across countries. Moreover, we seek to empirically validate a model of the retail brand orientation–positional advantage–organisational performance relationship and to contribute to a more comprehensive understanding of the factors driving retailer performance. A mail survey was used to collect data from retail firms in Australia, USA and UK. The unit of analysis is the retail firm. Confirmatory factor analysis was employed to assess the measurement properties of the study constructs and structural equation modelling was performed to test the research model. The findings suggest that four elements of retail brand orientation (functionality, distinctiveness, augmentation and symbolism) play different roles in relation to certain aspects of positional advantage, which highlights the importance of developing strength in all four areas. Similarly, a position of superiority in only one aspect of a retailer's offer is insufficient to assure both financial and strategic returns.
