Enhancing the Age‐Hardening Response of Laser Powder‐Bed Fusion WE43 Alloy through Microstructural Control

open access: yesAdvanced Engineering Materials, EarlyView.
Laser powder‐bed fusion (L‐PBF) can produce dense WE43 magnesium alloy parts, but their mechanical properties are limited by a nonhomogeneous microstructure. This study investigates the effects of varying direct aging (T5) and artificial age‐hardening (T6) conditions on microstructure and strength. Optimized T6 treatment significantly improves strength

A Study on Thermal Expansion and Thermomechanical Behavior of Composite Metal Foams

open access: yesAdvanced Engineering Materials, EarlyView.
The coefficient of thermal expansion of steel–steel composite metal foam (S‐S CMF) is shown to be lower than that of bulk stainless steel while its performance under compression demonstrate excellent mechanical stability and strength at all temperatures with gradualsoftening from 400 to 600 °C.
