Differential Heat Treatment Response of Cast plus Homogenized and Forged Billets of Aluminum Alloy AA7075
TL;DR: In this article, a thorough heat treatment study has been carried out on cast plus homogenized (ACH) condition billets as well as on forged (ACHF) billets, and the response of the alloy in these two initial conditions to various heat treatment tempers T6, T73, and RRA (Retrogression and reaging) has been studied.

Twin boundary defects-assisted dual-nanoprecipitation in a selective-laser-melted Al alloy
TL;DR: In this paper , a twin boundary-assisted dual-nanoprecipitation in a selective-laser-melted (SLM) Al alloy is systematically investigated, and the dual-noprecipient is primarily driven by the Gibbs-free energy difference between the incoherent twin boundaries with 9R phases and the adjacent matrix.

X-ray line broadening from filed aluminium and wolfram
G.K Williamson,W.H Hall +1 more
TL;DR: In this paper, the authors used a Geiger counter spectrometer to measure the changes in intensity distribution in the spectra of cold worked aluminium and wolfram and found that the line breadths may be attributed to simultaneous small particle size and strain broadening, the latter predominating at the higher Bragg angles.
