Abstract 93W alloys were prepared by means of vacuum liquid phase sintering， and the effects of gravity on the shape and microstructure of 93W alloys parts were investigated. The result shows that gravity causes remarkable macroscopic deformation during the vacuum liquid phase sintering of 93W alloys. Moreover， the gravity leads to obvious microstructure segregation phenomenon， and the densities increase linearly in the direction of gravity.
