锻造变形是在锻造过程中出现变形,一般情况下,变形的锻造下来的产品都是不合格的。变形量大于10%时高温强度和塑性下降,其原因是孪晶与晶界相交阻碍了晶界滑动,相交部分在外力作用下易产生应力集中导致裂纹萌生并沿晶界扩展.
对不同锻造变形量的钨合金材料组织、性能及其再结晶行为进行了研究。
The investigation was made on microstructure, mechanical property and recrystallization behavior of tungsten alloy with different amount of swaged deformation.
结果表明经高温锻造变形绝大多数缺陷可以在合适的力学条件下修复,但修复机制和条件大不相同。
It shows that most of internal defects can be recovered in properly mechanical conditions at the high...
