Abstract

Process for treating metallic materials, especially for consolidating the structure of metallic materials comprises producing a blank of the metallic materials, heating to a deformation temperature and deforming the blank. An Independent claim is also included for a blank made from titanium aluminide. Preferably deformation is exerted by producing torsion or compressing. Heating is carried out using electrical induction. Deformation is carried out at 1,000 degrees C.

Description

technical field

[0001] The invention relates to a method for the treatment of metal materials, in particular for strengthening the structure of metal materials, and to a metal blank. Background technique

[0002] The strengthening results achieved by the traditional metal material processing and forming techniques used so far generally cannot meet the desired requirements. Some special metal materials, such as titanium aluminum alloy (Titanaluminide) family or magnesium material family, according to the traditional processing and forming technology currently used, such as by forging or extrusion, always have obvious chemical and structural inhomogeneity , which cannot be tolerated in certain technical applications. A disadvantage of the known processing and shaping techniques is firstly that they can only achieve relatively low degrees of deformation. This is unacceptable when these metallic materials are used, for example, in applications with high thermal and mechanical ...
