摘要

冲击力场中

在材料冲击面上的压强近乎无穷大

韧性来源于材料的局部位移。理论上能提高材料局部快速位移的手段都能提高材料的韧性。对于所有以颗粒形式增韧的体系

颗粒和基体之间形成弹性过渡区

从而实现“破裂－下楔－压缩－应力方向改变”是增韧的基本模式。

Abstract

Under the impacting stress

the pressure on the surface of the bulk is almost infinite and toughenment is based on the localized displacement of material. Any material can be toughened by the measurement that enhances the shift ability of the sample. Between the particle and the bulk

transition area is critical in the particle toughening system

and a new mechanism is postulated "cracking-wedging-compressing-altering the direction of the impacting force"

which can explain all the phenomena in the experiment.
