Aluminum alloys are produced by different manufacturing techniques and each technique produces a unique microstructure. One of the most versatile manufacturing methods is powder metallurgy (P/M) because it produces a final fine or ultrafine grain microstructure. But it requires powder consolidation and densification processes after P/M. In the other side, Hot Isostatic Pressing (HIP) is now recognized as a very interesting technique to densify advanced materials with a high potential. The aims of this work are: to produce an AA1100 aluminum billet by powder densification followed by HIP and to compare its microstructure and mechanical properties against the ones of an AA1100 aluminum plate produced by conventional rolling. The mechanical properties were measured using tensile test and Charpy test. The results show that the tensile strength of the P/M+HIP sample is higher than the one of the aluminum plate, but the yield strengths are similar. In the other hand the impact toughness results are very different from each other.

“…Mähler and Kebriaei performed several numerical analyses on ring rolling technology [ 8 ]. To reduce the porosity in the PM components and improve their mechanical properties, different techniques, like warm compaction [ 9 ], high speed pressing [ 10 ], copper-impregnation [ 11 ], double-press and double-sinter [ 12 ], powder forging [ 13 ] and hot isostatic pressing [ 14 ], were developed to manufacture high-performance PM components. These techniques can improve PM components’ properties and more PM components can be used in the auto industry.…”

Effect of Surface Densification on the Microstructure and Mechanical Properties of Powder Metallurgical Gears by Using a Surface Rolling Process

et al. 2016

Powder metallurgy (PM) components are widely used in the auto industry due to the advantage of net-shape forming, low cost, and high efficiency. Still, usage of PM components is limited in the auto industry when encountering rigorous situations, like heavy load, due to lower strength, hardness, wear resistance, and other properties compared to wrought components due to the existence of massive pores in the PM components. In this study, through combining the powder metallurgy process and rolling process, the pores in the PM components were decreased and a homogenous densified layer was formed on the surface, which resulted in the enhancement of the strength, hardness, wear resistance, and other properties, which can expand its range of application. In this paper, we study the impact of different rolling feeds on the performance of the components’ surfaces. We found that with the increase of the rolling feed, the depth of the densified layer increased.
