Optimal design for heavy forging robot grippers

, 2010
This paper analyzes three typical mechanisms of heavy forging robot grippers: pulling with a sliding block including short- and long-leveraged grippers and pushing leveraged grippers, and uses multi-objective evolutionary genetic algorithm to design the ...

Decreasing the mechanical anisotropy of the forged Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy by modulating blocky LPSO particles using multi-directional forging

Journal of Magnesium and Alloys
The blocky LPSO particles were modulated by single-directional and multi-directional forging, and the effect of blocky LPSO particles on the anisotropy of mechanical properties of Mg-8.5Gd-2.5Y-1.5Zn-0.5Zr alloy forged parts was investigated.

Effect of multidirectional forging and equal channel angular pressing on ultrafine grain formation in a Cu-Cr-Zr alloy [PDF]

, 2014
The microstructure evolution was investigated in a Cu-0.3%Cr -0.5%Zr alloy subjected to large plastic deformation at temperature of 400° C. Two methods of large plastic deformation, i.e., equal channel ang ular pressing (ECAP) and multidirectional ...
