振动时效与热时效消除铸造应力工艺比较

Comparison between Vibration Ageing and Heat Ageing Used for Casting Stress Elimination

介绍了铸件残余应力的产生原因和危害,详细阐述了热时效和振动时效消除残余应力的工艺方法,并对两种时效处理工艺过程、应力消除效果、成本、节能降耗等进行了介绍和比较。

The reason and harmfulness of residual casting stress was introduced, and the heat ageing process and vibration ageing process used for residual stress elimination was described in detail. Two types of ageing treatment process, their effect on stress elimination, cost, energy conservation and consumption reduction, etc. were introduced and compared.
