【摘要】 对新型精铸模具钢制热锻模具的失效进行了分析,并对不同形式下模具的失效原因作了探讨。结果表明,精铸热锻模的主要失效形式为热磨损、塑性变形、热疲劳裂纹、冲击疲劳破断和脆性断裂。更多还原

【Abstract】 The failure dies of hot forged cast dies made by a new type of cast steel have been analyzed. The failure causes of different failure patterns are discussed. The results show that hot-forged cast dies take thermal wear, plastic deformation, thermal fatigue, impact fatigue fracture and brittle fracture as predominant failure patterns.更多还原
