Composition optimization of amorphous AlNiZr alloys

In order to solve the problem that the glass forming ability of Al-based amorphous alloy is not easy to be evaluated because of the easy precipitation of α-Al crystal in the glass forming process,a simple and feasible glass forming ability evaluation scheme was designedto optimize the composition of...
