高应变速率超塑性 high strain rate superplasticity
The results indicate that stress–strain curve shows strain softening at high strain rates. That is, with the increase of strain,flow stress increases first, when it reaches a peak, it gradually reduces.
结果表明,高应变速率时的应力-应变关系曲线大致呈应变软化型,即随应变的增加,流动应力先是增加,达到某一峰值应力后,又逐渐降低。
