Microstructure of （TiB+TiC）/TC18 Titanium Matrix Composite Undergoing Heat Treatment

School of Mechanical Engineering, Taizhou University, Taizhou 318000, Zhejiang, China

摘要: 使用真空自耗炉制备出三种Ti-5Al-5Mo-5V-1Fe-1Cr钛基复合材料。凝固过程中通过微量B₄C和Ti的反应生成微量TiB和TiC, 添加B₄C的质量分数依次为0.1%、0.2%、0.4%, 制备出的样品经过热加工和热处理, β晶粒被大幅细化, 但是β晶粒细化幅度并没有和B₄C的量呈现线性关系, 而是细化幅度增长越来越缓慢。经过研究, 认为这与增强体加速了β晶粒合并有关。

Abstract: Three kinds of Ti-5Al-5Mo-5V-1Fe-1Cr titanium matrix composites reinforced with trace amount of TiB and TiC were fabricated via a consumable vacuum arc-remelting furnace in this work.The reinforcements were produced during solidification by the chemical reactions between B₄C and Ti.The mass fractions of B₄C were 0.1%,0.2% and 0.4%,respectively. The as-cast ingots were subjected to thermomechanical processing and heat treatment.The β phase in the composites was significantly refined.However,with increase of the B₄C content,the refining extent of β grains was not linearly related but increased more and more slowly.It was suggested that this should be related to the accelerating effects of the reinforcements on the merging of β grains.
