摘要

通过分析加工硬化随应力的变化,可以深入了解材料系统中的应力-应变机制。使用一种包含快速加工硬化(阶段 3)和应力渐近平缓(阶段 4)两种行为的构成关系,可以评估塑性的开始,并将其与随后的塑性变形直至结构失稳联系起来。本文介绍了 Ti-6Al-4V 的机械行为分析结果,其中发现阶段 3 和阶段 4 的加工硬化变化:通过构成关系相互依存;适用于屈服强度的霍尔-佩奇公式;为两点斜率拟合法提供基础,以模拟实验加工硬化和应力应变行为。

On the Onset of Plasticity: Determination of Strength and Ductility
The analysis of the work hardening variation with stress reveals insight to operative stress-strain mechanisms in material systems. The onset of plasticity can be assessed and related to ensuing plastic deformation up to the structural instability using one constitutive relationship that incorporates both behaviors of rapid work hardening (Stage 3) and the asymptotic leveling of stress (Stage 4). Results are presented for the mechanical behavior analysis of Ti-6Al-4V wherein the work hardening variation of Stages 3 and 4 are found to: be dependent through a constitutive relationship; be useful in a Hall-Petch formulation of yield strength; and provide the basis for a two point-slope fit method to model the experimental work hardening and stress-strain behavior.
