On low temperature bainite transformation characteristics using in-situ neutron diffraction and atom probe tomography

In-situ neutron diffraction was employed to monitor the evolution of nano-bainitic ferrite during low temperature isothermal heat treatment of austenite. The first 10 peaks (austenite, γ and ferrite, α) were monitored during austenization, homogenization, rapid cooling and isothermal holding at 573 K. Changes in the α-110 and γ-111 peaks were analysed to determine the volume fraction changes and hence the kinetics of the phase transformation. Asymmetry and broadening in the α-200 and γ-200 peaks were quantified to lattice parameter changes due to carbon redistribution as well as the effects of size and dislocation density. Atom Probe Tomography was used to confirm that, despite the presence of 1.5 mass % Si, carbide formation was evident. This carbide formation is the cause of poor ductility, which is lower than expected in such steels.

Digital shimmer: popular music and the intimate nexus between fan and star

Conception of ‘star performance’ through popular music is stratified which generates diverse and often contradictory forms of thought. For example, stars and celebrities plausibly act as a ‘culture medium’ in which, through imagination, one’s identity is assembled, realised or constructed. What to become and how to be are questions we individually and collectively contend with throughout our lives to varying degrees (Maslow, 1954; 1968). Predominant use of digital technologies has seen the delivery of sound much altered. Music, be it Giuseppe Verdi’s La Traviata or Iron Maiden’s The Number of the Beast, once sourced via analogue legacy devices such as ‘old-school’ tape cassette or vinyl record is now a series of zero and one digits. Advocates argue that the key benefit of digitalisation is the ability to compress data because sound generates large files of information. The discourse of digitalisation begs the question of how a series of ones and zeros, albeit in a plethora of configurations, registers with listening bodies and affects ‘the sublime’. It is without doubt that some musical experiences afford indescribable, unlocatable sensation—even enchantment (as defined by Bennett, 2001: 5 and called forth by Redmond: 2014: 126). Such musical experiences might be in the presence of the performer or in their absence such as in the case of recorded music. In this context, any sense of ’real’ space and place is less definitive allowing for ‘special encounters’ to be imagined and felt. For these reasons, music and all that the use of the word might convey, the proposed notion of phaino-ken here, acts as the lens through which to examine the meaning and value of celebrity and star embodiment.
