Estudo da influência da pressão de compactação nas propriedades físicas e mecânicas de peças de aço processadas por metalurgia do pó

Abstract

The metal is not the new manufacturing process, however, this method as today, only its first steps in the 1920s and had major advances during the 20th century. Currently, powder manufacturing is a manufacturing process used because this process is the cheapest in the production of some parts and, sometimes, because it is the only viable manufacturing process. The present work intends to study the effects that a compaction pressure has on the physical and mechanical properties of iron parts processed by means of powder metallurgy, optimizing the metal process. For this, iron powder was used as the material for being the most used in powder metallurgy, with about 70% of the products manufactured by these techniques made of ferrous alloys. For the purpose of analysis, this parameter can be accessed by 4 33.8 MPa, 31.8 MPa and 491.8 MPa. With each of physical properties and durability of the material. As a result, it was possible to notice that the increase in compaction pressure induced an increase in durability in addition to an increase in porosity.
