With a combination of hydrostatic stress and temperature, the stability of residual austenite can be delayed to much larger strains, possibly leading to enhanced ductility of the final wire, whereas the structural alignment of the second phase can contribute to higher strength. This paper presents experimental and theoretical results of the wiredrawing process using TRIP (TRansformation Induced Plasticity) steel with 0.09% C, 1.57% Mn, and 0.90% Si. Drawability was estimated with a Gleeble 3800 testing unit.
