Temperature rise up to melting under quasi-static loading conditions induced by adiabatic shear banding

Adiabatic shear banding propagating at very large speed was observed during the unstable fracture of TRIP-TWIP β -metastable Ti-12 wt% Mo alloy under quasi-static loading. The fusible coating method was used with five different coatings to assess the predicted temperature variations. Two one-dimensi...
