Abstract The compaction and sintering conditions required for avoidance of swelling and development of very coarse pores during liquid phase sintering of mixed elemental titanium powder metallurgy alloys are described with reference to the titanium-nickel binary system. Swelling is minimised by using low compaction pressure or short sintering time. Swelling appears to require the presence of persistent liquid and closed pores. Gas pressure within closed pores is the probable mechanism of swelling
