Experimental Study on the Elastic–plastic Transitions of the Hetero-structured High Pressure Die Casting Mg–Al-RE Alloy
High pressure die casting (HPDC) Mg alloy has a hetero-structure in which the microstructures gradually coarsen from the casting surface to the interior, leading to the different elastic–plastic (E-P) transiti...
