Um estudo sobre o endurecimento, o processamento e propriedades mecânicas de uma liga de alumínio da série 3XXX tipo AA 3104 com adições de zinco

Modificações na composição química e no processamento termomecânico têm sido algumas das várias alternativas estudadas, para melhorar o desempenho de ligas de alumínio tradicionais. Neste trabalho foi modificada a composição de uma liga Al-Mn-Mg do tipo AA 3104, endurecível por deformação, adicionando-se diversos teores de zinco, transformando-a numa liga Al-Mn-Mg(Zn), endurecível por precipitação. O objetivo foi estudar e quantificar os efeitos do zinco sobre o processamento termomecânico e as propriedades mecânicas da liga modificada. Ligas com teores de zinco entre 0,03 a 1,52% foram fundidas e processadas obtendo-se um encruamento semelhante a condição H-19 industrial, denominada rota R. Ligas com teores de zinco entre 1,14 a 2,17% foram fundidas e processadas segundo três diferentes rotas: na rota S, o recozimento da rota R foi substituído por solubilização antes da laminação a frio; nas rotas E3H e E6H, as tiras laminadas a frio foram envelhecidas em dois estágios: 121°C por três horas para as duas rotas, mais três horas para a rota E3H e seis para a rota EH a 163°. A tensão de escoamento (SIGMA IND E) e a resistência à tração (SIGMA IND T) para a rota R aumentaram da ordem de 18% e 19% respectivamente, com o aumento do teor de zinco, enquanto o alongamento (E) permaneceu em torno de 4,5%. As propriedades mecânicas (SIGMA IND E SIGMA T E ) AUMENTARAM EM TORNO DE 25%, 31% E 27%, respectivamente, para a rota S. Considerando concentrações aproximadamente iguais de zinco, não foram verificadas diferenças significativas para (SIGMA E SIGMA T), entre as rotas R E S, no entanto, a rota S apresentou alongamento médio maior que a rota R da ordem 44%. Os menores valores de (SIGMA IND E SIGMA IND T) e os maiores valores de E foram obtidos para a rota E6H.

Analise dos esforços de laminação no dimensionamento de um laminador de bancada

The industry produces rolled, starting to and passing through casting forming processes, for example, in the case in question the rolling. A large portion of rolled products are flat, these have specific characteristics during their production and properties after finished that must be analyzed. For this a study of these properties must be made in materials samples, in order to be able to first know the material in question or provide new properties to the material through the process of rolling flat products. In this way is interesting that the students of mechanical engineering have knowledge of rolling trials, and from this can better understand the behavior of rolled. With this purpose the project of a benchtop rolling mill for the rolling of flat is needed, this work is the project of a sizing of one rolling mill non-ferrous materials

Estudo da fluência dos aços inoxidáveis ferríticos estabilizados ao titânio e nióbio e simulação numérica do processo no abaqus

The purpose of this research was tested a finite element model (FEM) that represented the creep of a slab during the reheating process of hot rolling. The aim is to prevent creep phenomenon changing the reheating profile with hot tensile test in Gleeble 3500, and, also, understand the former defect crisis. The goal of this work is to have a predictive tool to optimize the reheating process changing parameters (length and thickness). Then, use input parameters obtained from the tests to approximate the solution of the problem aided by Abaqus CAE. The results have showed that the ferritic stainless steel AISI 409 has a lower sensitivity to creep comparing to the stainless steel AISI 409, AISI 430Ti, AISI 441 and AISI 444

A company must have full knowledge and control of its operations so as to meet the market requirements and meet their production goals. Thus this paper uses the Taguchi method to extend the operational control of a cutting process by fusion of a synthetic fabric in the longitudinal direction. For process analysis and tracking of possible causes of the problem techniques of Production Engineering as the cause and effect diagram, also known as Ishikawa diagram, and design of experiments were used, the last one was applied to the design techniques of Taguchi. Finally the preparation method of understanding and design of experiment was due to the use of the software MINITAB v15 ®, which showed that the speed of rolling the fabric after cutting is crucial for controlling the entire operation

Caracterização do defeito tipo trinca de laminação, ocorrido no processo de laminação de barras de aço

The mechanical forming processes are the main means of transformation. Among all processes, the most used is rolling and broken down into flat and non-flat products. In the flat products are classified plates, and products no plans bars and profiles. Thus laminating products, mostly, are the raw materials for other processes of transformation, as stamping, forging, machining, bending and more. This work has focused on non-flat products, classified as bars and rods, watching a key point in the proceedings that is the product quality. Here is demonstrated through metallographic analysis of steel bars, hot-rolled, the characteristics of surface cracks in these bars

Mapeamento geológico-geontécnico de trecho da estrada vicinal na Serra de Itaqueri, Charqueada (SP)

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature
