The effects of Fe additions on the liquid phase sintering of W-bronze composites

摘要

In this investigation, experiments were conducted to evaluate the effects of Fe additives in the range of l-5 wt. percent on the densification of different compositions of W-pre-alloy bronze compacts sintered isothermally at temperatures ranging from 900 deg C to 965 deg C for 2.30 h. The results showed that substantial improvement in hardness by a factor of two folds and density by 10 percent was achieved for the W-pre-alloy bronze sintered compacts by the addition of 2-3 wt. percent Fe as an activator.
