文摘

New explanation for hardening mechanism in TRIP-assisted steel.

Work-hardening described by physically based model for pre- and post-yield behaviour.

Matrix yielding is followed by stress-assisted transformation of austenite to martensite.

Transformation hardening counters matrix softening and extends ductility.

Diffuse plastic instability occurs after austenite transformation is complete.
