Effect of Laser Shock Peening Parameters on Residual Stresses and Corrosion Fatigue of AA5083

Description: Article examining Aluminium alloy 5083 subjected to Laser Shock Peening both with (LSP) and without protective coating (LPwC) at multiple pulse densities.

Ordering-mediated local nano-clustering results in unusually large Hall-Petch strengthening coefficients in high entropy alloys

Description: This article reports a dramatic increase in the grain boundary strengthening or Hall-Petch coefficient, K, by systematically investigating the effect of Al addition on tensile yield strength in CoFeNi and CoCrFeNi high entropy alloys (HEAs) or complex concentrated alloys (CCAs). Such a trend is attributed to the ordering mediated nano-clustering in Al containing HEA/CCAs.
