The gravitational effects on liquid phase sinteringThe liquid-phase sintering of heavy-metal PM alloys containing 78, 83, 88, 93, or 98 wt pct W plus Ni and Fe in a 7:3 ratio is investigated experimentally. The focus is on the potential role of gravity in phenomena such as specimen slumping and distortion, liquid migration, and microstructural coarsening. The results are presented in extensive graphs and micrographs and discussed in detail, and a preliminary grain-growth model is developed which accounts for the effects of contiguity and the volume fraction of solid.
