使用水雾化铁粉等原料制备十字形试样,对脱脂工艺、微观组织进行了分析,得到的理想脱脂工艺为:先以较快的速率升温到160℃,然后以1℃.min-1的速率升温到300℃,保温0.5h,再以1.5℃.min-1的速率升温到450℃,保温0.5h.烧结在1300℃进行.实验结果表明,通过优化脱脂工艺,使用流动温压工艺,可以制备出成本低廉、形状复杂的结构件. The cross-shaped sample was prepared by using water atomized iron powder and other raw materials. The degreasing process and microstructure were analyzed. The ideal degreasing process was as follows: firstly, the temperature was increased to 160 ° C at a faster rate, The temperature was raised to 300 ℃ and kept for 0.5h, then the temperature was raised to 450 ℃ and the temperature was kept at 450 ℃ for 0.5h at 1300 ℃ .The sintering was carried out at 1300 ℃ .The experimental results showed that by optimizing the degreasing process, , You can prepare a low-cost, complex shape of the structure.
