Considering the microstructure properties and the ion bombardment during the high rate process,we investigated the controlled microstructure evolution and the improved material quality by discharge power profiling,which improved the performance of solar cells.

A physical metallurgical model was made to predict microstructure evolution and mechanical properties of C-Mn steel plate during control rolling and control cooling process, which consists of four modules: reheating, recrystallization, phase transformation and mechanical properties.

Experimental method and parameters of liquidus forging are given in this paper to prepare the bellit for semi-solid process,and microstructure evolution of magnesium alloy ZK60-RE during semi-solid isothermal heat treatment is researched as well.

In order to study the effect of process parameters on microstructure evolution during multi-step forging,recrystallization and grain growth models were implemented into a finite element code,then coupling between thermo-mechanical and microstructure evolution was realized.
