IMPROVED SINTERED BRASS COMPACTS (PART II)
Abstract
IT WAS PREVIOUSLY REPORTED IN REPORT R-1503 (AD-216 495) that substantially higher tensile properties were obtained with sintered 70% Cu30% Zn brass compacts when lithium stearate, rather than the conventional zinc stearate, was used as the lubricant. In the current investigation i was found that further improvements in the properties of brass compacts were possible with higher sintering temperatures or longer periods of time with either a nitrogen or air furnace atmosphere. The highest properties attained in the sintered brass for the two optimum sintering conditions approach those of annealed wrought 70-30 brass. A study was made of the changes in microstructure of the brass with various sintering temperatures and periods of time. The significance of microstructure as an aid in predicting properties of sintered brass was apparent. (Author)
