It was studied that the mechanical alloying process of Fe and Ni powders under the protection of argon atmosphere. XRD and SEM were used to study the microstructure of powder during ballmilling process and the microhardness of powder for different ball milling times was measured. The results ...
The effectiveness of these two milling processes on alloying and grain refinement were compared. The MA powders were consolidated by a plasma activated sintering (PAS) process. The microstructural evolution was characterized and evaluated for both the starting MA powders and PAS consolidated specimens ...

Upcycled high-strength aluminum alloys from scrap through solid-phase alloying The authors propose a scalable solid phase process to upcycle aluminum scrap into a high-strength alloy with 200% strength improvement. The process reduces energy consumption and carbon emissions while making customizable materi...
Unique in bringing about a solid-state reaction at room temperature, mechanical alloying produces powders and compounds difficult or impossible to obtain by conventional techniques. Immediate and cost-effective industry applications of the resultant advanced materials are in cutting tools and high performanc...
Study of Oxidation Behaviour of Bond Coating Nanocomposites Ni-20Cr-6Al Powder Synthesized by Mechanical Alloying In this study, nano crystalline Ni-20Cr-6Al composite powder was produced using a high energy planetary ball milling and a two-stage process. Then the oxid... A Salarvand,VS Pour ...
Cr-doped Fe-Si mixed powder is prepared by the high-energy planetary ball milling,and the mechanical alloying process of Cr-doped Fe-Si is studied according to the results by X-ray diffraction(XRD).The results show that Fe,Cr and Si powder realizes mechanical alloying through the atomic diff...
Liquid metal dealloying is controlled by the selective dissolution of one element of a solid binary alloy in the liquid melt, which produces a porous structure of the immiscible element. The porous structure coarsens during the dealloying process by diffusion of the immiscible element along the ...
