引言蠕变是金属在恒定的載荷作用(或在恒定的应力条件下)緩慢地不断地产生的范性形变,对各种材料說来,由于試驗温度和应力的不同蠕变可能逐漸停止或者一直繼續到断裂。因此常常以金属的蠕变抗阻力——蠕变极限及蠕变的断裂抗阻力——长时强度作为材料高温的强度特性。
INTRODUCTION Creep is a constant, steady load (or under constant stress conditions) in which metals slowly and continuously produce a normal deformation. For various materials, creep may gradually cease due to different test temperatures and stresses Continue to break. So often the metal creep resistance - creep limit and creep rupture resistance - long-time strength as the material of high temperature strength characteristics.
