Abstract
ABSTRACT The tension–torsion properties and deformation microstructure of near β titanium alloy after various heat treatment have been investigated by transmission electron microscopy (TEM). The samples after aging treatment at 500°C for 8 h possesses obviously higher strength than those samples undergoing other different treatment on account of thin α” plates distributing uniformly in the β grains. Interestingly, precipitation of α″-martensite in α plates were observed for the first time under tension–torsion deformation. The abnormal precipitation behaviour was attributed mainly to the large tensile-shear stress.
期刊介绍：
Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate.
Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
