主要從位錯、晶格滑移等金屬學理論上去解釋振動時效的機理。
主要觀點是振動時效處理過程實際上是通過在工件的共振狀態下，給工件的每一個部位（從微觀角度說是工件裏的每一個微觀晶格）施加一定的動能量
，如果施加的這個能量值與微觀組織本身原有的能量值（殘餘應力本身是一種勢能）之和
，足以克服微觀組織周圍的井勢（也可以說是對恢複平衡的束縛力），zeweiguanquyubiranhuichanshengsuxingbianxing，shichanshengcanyuyinglidewaiqujinggedeyimanmandihuifupinghengzhuangtai

，就能消除包括垂直主應力方向上的所有殘餘應力等。
