Enhanced precipitation strengthening of Mg-Al-Sn-Ca alloy by multidirectional rolling
Z Li, Y Miao, F Liu, P Ma, H Wang - Materialia, 2021 - Elsevier
The control of precipitation density has always been a difficult issue in the application of
precipitation strengthening mechanism. Here we reported the precipitation of Mg 2 Ca in a
novel Mg-2Al-0.8 Sn-0.5 Ca (wt.%, ATX2105) alloy promoted by multidirectional rolling.
Microstructure characterization revealed that the dislocation density of the multidirectional
rolling ATX2105 sample was 3. 6× 1 0 13 m− 2 higher than that of unidirectional rolling
sample after the second pass of rolling, which can effectively promote the precipitation of Mg …
