Investigation into the hot forming-quenching integrated process with cold dies for high strength aluminum alloy
TL;DR: In this paper, two different hot forming routes were proposed, i.e., hot forming-quenching integrated process with cold dies (HFQ®+120°C/24 h) and HFQ® + pre-ageing+ Â simulated baking, respectively, and the results showed that the U-shaped parts exhibited good formability without obvious surface oxidation, and overall mechanical properties were evenly distributed.

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.
