真空热处理对95W-3.5Ni-1.5Fe高密度合金组织和性能的影响

Effect of Vacuum Heat Treatment on Structure and Property of Heavy Alloy 95W-3.5Ni-1.5Fe

研究了真空热处理对95W－3．5Ni－1．5Fe高密度钨合金性能的影响。经真空热处理后，不但消除了氢脆的影响，还减少了磷的晶界偏析程度，使合金强韧性得到了改善。

The effect of vacuum heat treatment on the mechanical properties of 95W-3. 5Ni-1. 5Fe heavy alloy was investigated in this paper. Vacuum heat treatment not only inhibits hydrogen brittleness,but also reduces significantly the phosphorus segregation along grain boundaries and thus improves strength and toughness remarkably.
