Abstract
In the process of production of Ti-6Al-4V alloy, which consists of blending of extra-low-chlorine T i and 60mass%Al-40mass%V master alloy, cold compaction, vacuum sintering and hot forging, the influence of compaction stress and sintering conditions on the density of sintered compacts and various forging characteristics of the sintered compacts were investigated.<BR>The increasing rate of the compact density during heating up to sintering temperature depends on density of the green compact and heating time, with which it has a linear correlation. The increasing rate of the compact density during holding at sintering temperature is in proportion to the power of the holding time. The empirical equation of the density change during sintering was derived from these findings, and confirmed to coincide well with experimental values.<BR>The density after forging is strongly influenced by pressure and plastic deformation during forging. Tile holes in the compact can be rejected completely by suitable forging condition, except the surface area of the compact where the temperature reduces rapidly compared with that of the inner part of the compact.
