摘要

本文研究了烧结时间对粉末冶金材料尺寸特性的影响。本研究使用的粉末是含Cu、Ni和Mo的铁基预合金粉末。粉末在600 MPa下单次压制，圆盘试样尺寸为8-6 mm。绿色粉饼在1150摄氏度的实验室炉中烧结60、75和90分钟，然后风冷到室温。对坯体和烧结试样的密度、孔隙率和尺寸变化进行了评价。

The Investigation on Dimensional Stability in Some Sintered Powder Metallurgy Alloys

The subject of this research was to study the effect of sintering time on the dimensional characteristics of some powder metallurgy (PM) materials. The powders used in this study are prealloyed iron-based powders with Cu, Ni and Mo. The powders were single pressed at 600 MPa and the disc specimens have the dimensions of 8-6 mm. The green compacts were sintering in a laboratory furnace at 1150 ºC for 60, 75 and 90 minutes and air-cooled to room temperature. The density of green and sintered specimens, the porosity and the dimensional changes were evaluated.
