Experimental Study and Numerical Simulation of Directionally Solidified Turbine Blade Casting

Jing YU , Qingyan XU , Baicheng LIU , Jiarong LI , Hailong YUAN , Haipeng JIN

材料科学技术(英文)

The directional solidification process of turbine blade sample castings was investigated in the work. Variable withdrawal rates were used in one withdrawal process and compared with the other using uniform rate. A mathematical model for heat radiation transfer and microstructure simulation of direct...

Shrinkage behaviour of spheroidal graphite cast iron in green and dry sand molds for the benchmarking of solidification simulation

Wenzhen LI , Baicheng LIU , Jiarong LI

材料科学技术(英文)

The effects of metallurgical and processing parameters on the formation of shrinkage cavities and porosities in spheroidal graphite cast iron have been studied, considering the parameters of carbon equivalent, inoculation, casting modulus, mold type (green or dry) and pouring temperature within spec...
