Prediction of grain size for blade precision forging process under thermo-mechanical coupling

He YANG , Yuli LIU , Wang CAI , Mei ZHAN

材料科学技术(英文)

Blade precision forging is a high temperature and large plastic deformation process. Interact of deformation and heat conduction results in producing large temperature unevenness inside the billet. The unevenness has a great effect on the mechanical property and microstructure of the forged blade. H...

Role of Friction in Cold Ring Rolling

He YANG

材料科学技术(英文)

Cold ring rolling is an advanced but complex metal forming process under coupled effects with multi-factors, such as geometry sizes of rolls and ring blank, material, forming process parameters and friction, etc. Among these factors, friction between rolls and ring blank plays an important role in k...

Effect of deformation condition on axial compressive precision forming process of tube with curling die

He YANG , Zhichao SUN

材料科学技术(英文)

The effect of the deformation condition on the axial compressive precision forming process of tube with curling die was investigated by using a rigid-plastic FEM. The results show that the forming accuracy depends mainly on geometric condition r(ρ)/d(0), little on tube material properties and fricti...
