Influence of Pre-strain on Mechanical Behavior of Austenitic Stainless Steel and Construction of Constitutive Models
Mechanical behavior of 316L austenitic stainless steel with different pre-strains was studied at different temperatures of 293-573K and strain rates of 0.0005-0.01s<sup>-1</sup>, and the effect of pre-strain on mechanical behavior was investigated. The results show that yield strength of...

description | Mechanical behavior of 316L austenitic stainless steel with different pre-strains was studied at different temperatures of 293-573K and strain rates of 0.0005-0.01s<sup>-1</sup>, and the effect of pre-strain on mechanical behavior was investigated. The results show that yield strength of 316L stainless steel increases and elongation decreases evidently with pre-strain, and tensile strength basically remains constant with pre-strain. In addition, strain rate sensitivity, temperature sensitivity and strain hardening of 316L stainless steel are inhibited by pre-strain. The effect of pre-strain on mechanical behavior is related to dislocation accumulation and mechanical twin produced in the pre-strain process. According to the variation rule of mechanical behavior with pre-strain, the constitutive models considering pre-strain including Modified Johnson Cook (MJC) and Modified Zerilli-Armstrong (MZA) were constructed. The comparison of experimental results shows that the predicted results of two modified models are in agreement with the experimental data. |
