Powder Metallurgy Production of Ti-5.4 wt.% Alloy.
II. Structure and Strength of Sintered Material

Abstract

The powder metallurgy production of porous Ti-5.4 wt.% Si material promising for solid oxide fuel cells is studied. Its structure and mechanical properties are examined. It is shown that compacting pressure in the range under study has no essential effect on the structure of green powder samples before the next sintering. The volume shrinkage of samples starts to increase with sintering temperature from 1300 °C up to the solidus point. Variation in sintering conditions of compacts from atomized Ti-5.4 wt.% Si alloy powder allows the material density to be changed in a wide range.
