Brittle-to-ductile transition in Ti–Pt intermetallic compounds
Phase transformation changes numerous properties of materials. Ti-Pt alloys have received much interest because of high martensitic transformation temperature. However, the intrinsic brittleness of these intermetallic compounds with low crystal symmetry and complicated phase structure limit their applications, especially when composition deviates from ...

Ductile and brittle transition behavior of titanium alloys in ultra-precision machining
Titanium alloys are extensively applied in biomedical industries due to their excellent material properties. However, they are recognized as difficult to cut materials due to their low thermal conductivity, which induces a complexity to their deformation
