Resumo
Actually the powder metallurgy technique (MP) have been developed several techniques using the same principle combined forming and processing with new technologies such as rapid prototyping and powder injection that is focus of this study and combines the similar process to plastic injection with metallic particles. The injection of particulate (powder) metal combines techniques of plastic injection with the powder metallurgy combining versatility with repeatability. This work had as main objective the microstructural and mechanical characterization of a component obtained by powder injection molding of 316L stainless steel (austenitic), one of the most used materials by this technique, comparing them with other processing of the same material under study. The research involved the choice of particulates (powders) available, classification of the mixture with different binders, the rheological characteristics to the sintered material, manufacturing of parts for injection and standard procedure for setting parameters for component manufacturing. After processing the material, in accordance with metallic particles available for manufacturing, it was concluded that (a) the powder production quality directly influences the grains formed by processing; (b) the average growth of the grain structure that formed the final component was relatively low; (c) the grain well defined shapes in accordance with the appropriate production controls. Can detect it uniformity in manufacturing the components.
