Abstract

The mechanical performance of TRIP-120 a novel transformation induced plasticity steel alloy, is evaluated for different loading cases and strain rates. The performance is compared with HSLA-100, a low-alloy steel developed by the United States Navy and currently used in naval hulls. The response of these materials under uniaxial tension and shear was investigated to the point of fracture at isothermal and adiabatic conditions. TRIP-120 shows a significant improvement in dissipated energy at fracture compared to HSLA-100. SEM images of ductile fracture surfaces for tensile and torsion samples of both TRIP-120 and HSLA-100 are compared, and the presence of transformed martensite in the TRIP-120 dynamic torsion specimens is confirmed with optical microscopy and magnetometry.
