Fracture mechanisms in flat and cylindrical tensile specimens of TRIP-TWIP <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" altimg="si13.svg"><mml:mi>β</mml:mi></mml:math>-metastable Ti-12Mo alloy

Enhanced mechanical properties in terms of strain hardening capacity and uniform have been measured for recently developed TRIP-TWIP β−metastable Ti alloys. However, hardly anything has reported about their fracture properties. An original scenario including adiabatic shear banding is proposed both flat cylindrical tensile specimens Ti-12wt.% Mo tested quasi-static conditions at room temperature. The geometry the a strong influence on mechanism. fusible coating method was used with Sn Cu coatings to qualitatively evaluate evolution temperature during fracture, colder than 232°C crack initiation increasing up melting alloy propagation. High-speed imaging also estimate propagation speed, 1,840 m.s−1, level corresponding unstable rise speed linked specific patterns.
