摘要
按不同Cr元素添量制备试样,研究TC4钛合金纤维组织及力学性能,旨在优化制备工艺,控制Cr添量,提升TC4钛合金综合性能.研究表明:烧结合金在w(Cr)≤2％时呈双态组织特征;相比不掺入Cr元素的TC4钛合金强度,掺量为2％时的强度提高6.7％,达到926 MPa,韧性增强;TC4钛合金具有魏氏组织特征,对应w(Cr)为3％、4％;合金强度因Cr含量的增加而提高.该研究内容为TC4钛合金工艺优化提供技术指导,实现Cr添量合理控制,发挥Cr元素性能优势,提高钛合金生产质量.
Abstract
Samples were prepared with different amounts of Cr element to study the microstructure and mechanical properties of TC4 titanium alloy fibers,aiming to optimize the preparation process,control the Cr addition,and improve the comprehensive performance of TC4 titanium alloy.Research has shown that sintered alloys exhibit bimodal microstructure characteristics when w(Cr)≤ 2％.Compared with TC4 titanium alloy without Cr element,the strength increased by 6.7％and reached 926 MPa at a content of 2％,with enhanced toughness.TC4 titanium alloy has Weibull microstructure characteristics,corresponding to w(Cr)of 3％and 4％.The strength of the alloy increases with the increase of Cr content.This research provides technical guidance for the optimization of TC4 titanium alloy process,achieving reasonable control of Cr addition,leveraging the performance advantages of Cr element,and improving the production quality of titanium alloy.
