Research Progress on the Thermal Deformation Behavior of TC18 Titanium Alloy Large-size Bars
摘要
Abstract
In recent years,with the continuous development of large-scale free forging equipment,the demand for large-scale forgings for aerospace key structural parts has increased sharply,and the preparation of large bars has become the focus of scientific research and industrial production.TC18 titanium alloy,a type of high-strength and high-toughness titanium alloy with high alloying and thermal deformation parameter sensitivity,has gradually become the core structural material of key aerospace equipment.Therefore,large-scale bars have become a key area of research and production in recent years.In this paper,the methods used to produce large TC18 titanium alloy bars(φ300～φ500 mm)in recent years are discussed,the related research on the numerical simulation of the thermal deformation of TC18 titanium alloy is summarized,the current situation of ingot melting,forging and heat treatment technology is analysed,and the existing problems and solutions for large bars are summarized.Finally,considering the future research focus of the raw material preparation process,combined with the demand of users for TC18 titanium alloy bars,we will strive to open up the whole process of manufacturing raw materials and finished forgings in the future and realize personalized design of processes and quantitative control of microstructure and properties.关键词
