| Abstract | ||
| ABSTRACT Powder metallurgy (P/M) processes using sintering are able to form net-shaped products and have been used widely in the production of automobile parts to improve productivity. In this work, an experimental and numerical study on the substitution by P/M in automotive parts was carried out. Aluminium alloy A356 powder was used in the experimental part while stainless steel 316L powder was the material of choice in the numerical study. The A356 powder was shaped by a uniaxial press then sintered at 520 ºC. The density, compressive strength, and hardness of the produced part were evaluated and compared to the values for the same material produced by the permanent mould cast process. In the simulation component of this study, ANSYS™ Finite Element software was used to model an axisymmetric flanged part via the LSDYNA ™ module using the geological Cap material model. The effect of density distribution in the part was analyzed through the plastic strain that was generated. The result was compared to the experimental density map. | ||
