摘　　要：温压工艺的技术关键之一是润滑剂 ,其主要作用是减小压制过程中粉末颗粒与模壁之间及粉末颗粒之间的摩擦 ,增大有效压力 ,从而使压坯密度相对于传统压制工艺明显提高。不同润滑剂的润滑效果不同 ,最佳压制温度也有差异。本文选用 3种不同的润滑剂 ,在不同温度、压力条件下采用温压技术制备铁基粉末冶金材料 ,研究了压坯密度的变化规律和它的力学性能 。The use of lubricant is the key of warm compaction technology.Warm compaction can produce compacts with higher density compared to conventional compaction because it modifies the lubrication mode and increases the effective applied pressure by reducing the friction between the powder and the die wall and also the friction between the powder particles.Different lubricants produce different lubrication effects and their optimal compacting temperature will be different.In this paper,three different lubricants were used to study the effects of different lubricants on warm compaction process.Iron base samples were prepared using different processing temperature and pressure.The green compact density and mechanical property were studied.
