Design, development and application of titanium alloy materials

Due to the development of aerospace technology, titanium alloy research and development has been very active compared with sponge titanium. Great progress has been made in basic research, alloy properties research and application research. The effect of interstitial atoms on the strength and bulk modulus of titanium is studied. Progress has been made in the finite element simulation of the interface behavior of composite materials, the study of the ordered strengthening of alloys, and the study of the interaction between atoms and vacancy in alloys. In order to meet the application performance requirements of titanium materials in different fields, the design of alloy materials has large space and remarkable effect. For aerospace applications, BT37 alloy, NIN CT20 alloy, NIN Ti-600 alloy, Ti-60 alloy, "Ti15D alloy, NIN Ti-40 alloy, NIN Ti-26 alloy, and NIN Tp-650 alloy is a representative of new alloy materials studied at home and abroad in recent years that can meet the requirements of different components for data application performance. Some can also reduce the cost, reduce the mass, high temperature titanium alloys (such as Ti53311S research is also a hot spot) applied to the field of ships in the field of Timetal511 alloy, NIN TiB19 alloy and NIN Ti-91 alloy in toughness, corrosion resistance and sound permeability have been significantly improved for large ships.

Such as Ti-35ZRlonb alloy and Ti-29NB-13Ta 4.6Zr titanium alloy. The skeletal data developed by Tsinghua University in recent years is a typical representative of the application in the biological field. Golf clubs widely used in the civilian field use a titanium alloy called KSTil9, aircraft carrier) manufacturing and Marine industry development has a positive role in promoting. In the biological field, ZrNbTaPd and sn are mainly used as titanium alloy elements to enhance mechanical properties and biocompatibility, which greatly reduces the cost and improves the quality. Titanium rods and titanium alloys in construction, automotive, Marine engineering, medical and sporting goods and other aspects of the application of research began to increase, in recent years due to the civil promotion of titanium, especially in the field of seawater desalination application research has attracted widespread attention, medical titanium alloys 1C 20Ti 6A17Nb products have been in clinical application.
