Powder Metallurgy Techniques and Materials

In this study, pure magnesium (Mg) powder particles were produced by PM at different compaction pressure (100, 200, and 400 MPa). The effects of compaction pressure on the microstructure, corrosion behavior, and surface roughness of Mg have been investigated in detail. The microstructures of Mg samples produced at dif…

Determining the sintering parameters is decisive to optimising the tribological, physical, and mechanical performance of aluminium matrix alloys.In parts produced by powder metallurgy, the sintering stage directly determines the density, microstructural development, and the strength of metallurgical bonding between pa…

Abstract In this study, the effect of compression pressure on the properties of powder metallurgy materials produced with premixed commercial Alumix-123 powder without lubricant and with 1.5 wt. % zinc stearate lubricant was investigated. Differential scanning calorimetry and thermal gravimetric analyses were performe…

The present study examines the influence of nickel addition on the microstructural evolution, phase formation, hardness, and wear performance of Nb-V microalloyed powder metallurgy (PM) steels under both dry and corrosive sliding conditions. A series of Fe-C-Nb-V alloys containing 0-30 wt.% Ni were produced via powder…

Traditional powder metallurgy (PM) techniques typically produce functionally graded composite materials (FGCMs) with planar interfaces, which limit the design possibilities and mechanical performance of the resulting materials. In this study, a novel separator-assisted molding technique was developed to fabricate FGCM…

Mekanik bir sistemi oluşturan parçalar arasındaki bağıl hareket sonucunda parçalarda sürtünme ve aşınmalar enerji kaybına sebep olmaktadır. Aşınma, geri kazanılamayan bir madde kaybıdır. Bu çalışmada, genel makine imalatında yaygın kullanılan 1.6523 (AISI 8620), 1.2379 (AISI D2) ve Toolox 33 çeliklerin abrasif aşınma…
