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
