A phase stability determination method without empirical parameters and considering multivariate nonlinear coupling was proposed, revealing the composition design and strength-toughness matching strategy of ultra-high strength and toughness titanium alloys.

Revealed the mechanism of element volatilization in vacuum melting, proposed the method of increasing volatile elements to control composition; invented a new technology to reduce interstitial elements such as oxygen and nitrogen, revealed the formation mechanism of segregation in physical field-assisted casting,

The research team has built a multi-physics field coupling calculation model for centrifugal casting of super-large complex structure cylinder sleeves, developed a large database of multi-element micro-alloy cast iron cylinder sleeve material preparation processes for various working conditions,

The mechanism of element volatilization in vacuum melting was revealed, and the incremental volatile element method for controlling composition was proposed; a new technology for reducing interstitial elements such as oxygen and nitrogen was invented
