摘 要:
对再生高密度钨合金塑性的提高作了较为深入地研究。结果表明：向再生合金原料粉末中加入适量的Ni，Fe元素进行成分调节可显著提高再生合金的塑性；对再生合金进行真空热处理可明显提高再生合金塑性，与热处理前相比，再生合金延伸率提高了约43．4％，截面收缩率提高了约33．9％。[著者文摘]

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%.[著者文摘]
