铸造应力指的是铸件在凝固和以后的冷却过程中体积的变化不能自由的进行，于是在产生变形的同时还产生应力，这种应力称为铸造应力。
分析测定了中铬抗磨铸钢的流动性、缩孔率和铸造应力。
The casting fluidity, ratio of line contraction, casting stress and heat crack tendency were tested.
本研究用热弹塑性方法分析铸造应力框自凝固到冷却过程动态热应力。
In this research work, the thermal elastic-plastic method is used to analyze the dynamic thermal stress in the stress-frame specimen during its solidification and cooling process.
另一方面，热处理工艺不当使得铸造应力及机加工的残余应力无法彻底消除，这样加剧了裂纹的产生和扩展。
On the other hand, the improper heat treatment operation can not completely relieve the casting stress and remnant stress, and further enhances generation and expansion of cracks.
