Abstract
Friction stir welding caused formation of fine-equiaxed grains and stabilization of austenite phase up to 99.8% (promotion of TRIP effect) in the high-Ni TRIP steel. Ultimate tensile strength and elongation were increased from 980 MPa-61% to 1270 MPa-121%, which has been never reported before.
