Great progress has been made from basic research to alloy performance research to applied research. Study on the effect of interstitial atoms on titanium strength and bulk modulus, basic research. Progress has been made in finite element simulation research on the interface behavior of composite materials, research on ordered strengthening of alloys, research on the interaction between atoms and vacancies in alloys, etc.
In order to meet the application performance requirements of titanium materials in different fields, alloy material design work has a large space and significant effects. BT37 alloy, NIN CT20 alloy, NIN Ti-600 alloy, Ti-60 alloy, IT15D alloy, NIN Ti-40 alloy, NIN Ti-26 alloy, and NIN TP-650 alloy used in the aerospace field can meet different requirements in recent years. The requirements for material application performance of components are representatives of new grades of alloy materials studied at home and abroad. Some can also reduce costs and reduce quality. High-temperature titanium alloys (such as Ti53311S are also a hot topic in research) are used in the ship field, such as Timetal511 alloy, NIN TiB19 alloy and NIN Ti-91 alloy. They have excellent toughness, corrosion resistance and sound transmission. Sex and other aspects have been significantly improved.
For large ships such as Ti-35ZrlONb alloy and Ti-29Nb-13Ta-4.6Zr titanium alloy, etc. The skeletal data developed by Tsinghua University in recent years is a typical representative of applications in the biological field. Golf clubs widely used in the civilian field use a titanium alloy called KSTil9, which plays a positive role in promoting the manufacturing of aircraft carriers and the development of the marine industry. In the biological field, ZrNbTaPd and sn are mainly used as titanium alloy elements to enhance mechanical properties and biocompatibility, significantly reducing costs and improving quality.
