Effect Of Atmosphere Composition On Sintering Of Bronze

Premixed bronze powders are widely used to produce a wide variety of P/M components including bearings and bushings by the powder metal industry. The physical and mechanical properties of sintered bronze components such as dimensions, strength, microstructural characteristics, and sintered density are well known to change with sinlering furnace design, particle size distribution in powders, green density, preheating and sinlering time" and temperature, and protective atmosphere flow rate. " However, not much is known about the effect of protective atmosphere composition on physical and mechanical properties of sintered bronze components; This paper describes effects of protective atmosphere composition and sintering temperature on physical and mechanical properties of sintered bronze components
