摘要：

Thermally activated dislocation dynamics in austenitic FeMnC steels is investigated based on a collection of tensile yield stresses at different temperatures and strain rates of numerous steels available in the literature. A classical viscoplastic potential is suitable to describe the phenomena in binary FeMn alloys. The description of ternary FeMnC alloys is more complex as two basic mechanisms should be involved.
