During sintering the presence of a titanium hydride addition in a high-zinc brass powder promotes the reduction of the starting oxide films, prevents further oxidation, inhibits the evaporation of zinc, and decreases the thickness of the defective surface layer. As a result, mechanical properties are improved, the improvement being greatest in the sintering of an oxidized brass powder in an only partially dried atmosphere. Use of titanium hydride is not recommended in cases where high electrical and thermal conductivities and good polishing ability are required in sintered brass parts. [ABSTRACT FROM AUTHOR] |
