摘要: 采用放電等離子燒結(SPS)設備制備了93W-5.6Ni-1.4Fe高比重合金,燒結溫度范圍為1100~1180℃,保溫時間為5min.對不同燒結溫度下的樣品進行了密度、硬度、抗彎強度等性能測試,采用場發射SEM觀察了樣品表面形貌及斷裂行為.結果表明:采用SPS燒結,可以在較低的溫度下實現93W-5.6Ni-1.4Fe高比重合金的固相燒結,使合金致密化,并能有效控制鎢晶粒長大,提高材料的硬度、抗彎強度等力學性能.

Abstract: 93W-5.6Ni-1.4Fe cemented carbides were sintered by spark plasma sintering method, in which the sintering temperature ranged from 1100℃ to 1180℃ and the holding time was 5 min. The properties such as density, hardness and bending strength of the samples sintered at different temperatures were tested, and field spray scanning electron microscopy was used to investigate their appearance and rupture behavior. The results showed that 93W-5.6Ni-1.4Fe cemented carbides with high density were sintered by SPS at low temperature. Besides grain size could be controlled, the hardness and the bending strength could also be improved.
