Research in the Process of Cuboid Heavy Forging;

Study on Healing of Interior Crack-type Fault in Heavy Forging by Modeling;

In order to control the microstructure of heavy forgings,an optimization method based on composite design and numerical simulation was proposed.

The Repairing Study for the Defects Inside the Heavy Forgings;

Microstructure of heavy forgings robust parameters control methodology based on taguchi method;

In order to control the microstructure and fracture of heavy forgings,a multiobjective optimization method based on numerical simulation was proposed.

Numerical simulation and experimental validation of large forging during quenching process;

Our research invented one process of pre-heattreatment to correct the coarse original structure and the grain unhomogeneous of large forging, the process improved the mechanical properties of the forging.

According to the complexity and particularity of large forging process design, as well as the shortcoming of traditional manual method for process design, the key technologies of CAPP system are discussed, and the structure and function modules of forging CAPP are designed in this paper.

Through the analysis and study of the specifications for the forked type forgings,this article has set forth the required method to ensure the low temperature impact toughness of the forked type forgings from the aspects of processes of melting,forging and heat treatment.
