10~3A soft-switch current pulse generator for changing microstructure of the alloy;

Based on the principles of chemical corrosion, this article discussed how to use variant erodents of nitric acid in alcohol to reveal the metallographic structure of one phase alloy and multiphase alloy.

Improvement of experimental apparatus of dual alloy phase diagram;

On the basis of this model, the details of the calculation for four kinds of binary alloy phase diagram were presented in this work.

Based on the basic transfer process,including heat transfer and solute transfer,and the physics of growth process of crystal grains,the mathematical models for the 3D simulation of microstructure and free dendritic growth of single phase alloy were developed and a new capturing rule was presented.

The microstructure and alloy phases changes of the alloy on the states of casting, forging, rolling and rolling-annealing were systematically investigated by optical microscope and X-Ray.

One of the difficulties in the identification of magnesium alloy phases is the lacking of qualitative and accurately quantitative analysis means approporiate to the second phases in magnesium alloys, which leads to the shortage of knowledge including the evolution for some phases in magnesium alloys.
