从微观上看,只要温度在绝对零度以上,金属原子始终处于运动中,由于残余应力的影响,这些原子处于不平衡运动状态。但它们力求回复平衡位置,这就需要能量。振动时效就是给金属构件提供机械能,使约束金属原子复位的残余应力释放,加快金属原子回复平衡位置的速度。金属构件振动时吸收能量的速度比热时效和自然时效快得多,故效率高,节约能源。本文探讨基于位错运功和组织变化的微观振动机理。
From the microscopic point of view, as long as the temperature is above absolute zero, the metal atoms are always in motion. Due to the residual stress, these atoms are in an unbalanced state of motion. But they seek to restore equilibrium, which requires energy. Vibration aging is to provide mechanical energy to metal components, the release of residual stress to restrain the release of metal atoms to accelerate the speed of metal atoms to restore equilibrium position. Metal components vibrate when absorbing energy faster than thermal aging and natural aging much faster, so the high efficiency and energy conservation. This paper explores the mechanism of microscopic vibration based on the function of dislocation and organizational change.
