The Morphology of Rolling Contact Fatigue Fracture of Hardened Steels王绪,章守华,崔佩庸摘 要:<正> Rolling Contact Fatigue(RCF) is a cumulativedamage phenomenon when metals are subjectedto repeated contact stresses. The fomationof pitting on the contact surface is the resultof the rolling contact fatigue. The morphologiesof rolling contact fatigue fracture......
Fatigue fracture mechanism of AZ31B magnesium alloy and its welded joint ZHANG Hong-xia, WANG Wen-xian, WEI Ying-hui, LI Jin-yong, WANG Jian-ling College of Materials Science and Engineering.... The fatigue fracture mechanisms were analyzed by SEM. The fatigue fracture surface consists of quasi-cleavage patterns or cleavage step and a brittle fracture occurs. Numerous secondary cracks are observed......
