摘要:

将轧制成形与真空烧结相结合制备出大块多孔Ti--24Nb--4Zr--8Sn(%, 质量分数, 简称Ti2448)材料, 研究了冷轧形变量(20%--40%)和烧结温度(1100--1300℃)对其孔隙率、平均孔径、压缩强度及杨氏模量的影响。结果表明, 在烧结温度相同的情况下, 随着冷轧形变量的增加, 多孔Ti2448合金的孔隙率和平均孔径均减小, 压缩强度和弹性模量线性增加。烧结温度对多孔材料孔隙率及孔径的影响不大。在孔隙率相同的情况下, 多孔Ti2448合金的压缩强度和模量比明显优于纯钛多孔材料。

Abstract：

A massive porous Ti–24Nb–4Zr–8Sn(%, mass fraction, Ti2448)alloy was prepared by cold rolling forming and vacuum sintering process. The effect of rolling reduction (20%–40%) and sintering temperature (1100 ℃ –1300 ℃) on porosity, mean pore size, compressive strength and Young's modulus of porous Ti2448 alloy were investigated. The results show that porosity and mean pore size both decrease with increasing rolling reduction under the same sintering temperature, but compressive strength and elastic modulus increase linearly with increasing rolling reduction. The effect of sintering temperature on porosity and pore size of porous material is not obvious. The porous Ti2448 alloy excels porous pure Titanium in the ratio of compressive strength and elastic modulus for the same porosity.

Key words： metallic materials porous Ti–24Nb–4Zr–8Sn rolling forming elastic modulus mechanical properties
