Research Center for High Properties Titanium Alloy Material Preparation

Introduction
High-performance Titanium Alloys Research Institute focuses on High-end Key Material Preparation Technology Research and solves the key technical problems in the domestic production of titanium alloys. The ambition includes the localization and stabilization of producing high-performance titanium materials; the advancement of the comprehensive upgrade of materials performance of titanium alloys; the building of the core competitiveness of domestic high-tech materials, and the industrial upgrading in the field of non-ferrous metal deep processing. It will meet the demands of critical industries and vigorously promote the application of high-performance titanium alloys and high-temperature alloys in aerospace, civilian, marine and other key areas.


The Institute is mainly composed of relevant technical personnel with extensive experience in the titanium industry. The team has extensive experience in the preparation of high-performance titanium alloys, has achieved fruitful results in the processing and has many core technologies.

 


Core Technology
1.Titanium alloy composition design based on improved performance
The project team has studied the relationship between titanium alloy composition and titanium alloy microstructure and mechanical properties. With the experimental verification conducted, the effect of different elements in titanium alloy on the mechanical properties of titanium alloys is summarized. Based on this law, a variety of new titanium alloy materials have been developed.
 

2.High-Homogeneous and Clean Titanium Alloy Smelting Technology
A mathematical physics model of titanium alloy ingot melting was established, and a high homogenous clean titanium alloy ingot smelting method was invented to improve the uniformity and stability of titanium alloy ingot composition. Through raw material control, key process parameter control and other process control methods, good batch stability of high-average clean titanium alloy ingots is achieved.
 

3.High-quality titanium alloy bar/slab preparation technology
