On the enhancement of fatigueresistivity of Hadfield steel casting frog
论提高高锰钢辙叉疲劳抗力的途径
According to the principle of damage mechanics, the evolutional law of fatigue damage of pearlite ductile cast iron was studied with double arms electrical bridge for measuring electrical resistivity.
根据损伤力学原理，用双臂电桥测量电阻的方法，研究了珠光体球墨铸铁的疲劳损伤演变规律。
The change of electrical resistivity is very sensible to the fatigue damage of ductile cast iron.
