Effect of Processing on the Plasticity of Recycling Tungsten Alloy of High Density

Abstract:

Tungsten alloy scraps are considered as the second tungsten resource to recycle. The plasticity of recycled tungsten alloy has been deeply investigated in this paper. The study indicated that Ni and Fe powders of given amounts were added and mixed to the recycled powder can increase the plasticity of recycled alloy greatly. After vacuum heat treatment, the plastic behavior of recycled tungsten alloy was improved. For example, the elongation increased by about 43.4% and the cross section contraction ratio increased by about 33.9%.
