Microstructures and properties

The microstructural evolution of Al12Mg17 alloy during the quenching processes

“…Al 12 Mg 17 is the c-phase of the Al-Mg alloy with the a-Mn type structure, has a low melting point of approximately 730 K and is comparatively soft at lower temperature. Thus reducing the amount of Al 12 Mg 17 phase by addition of other elements and lowering the aluminum content to form relatively hard particles in grain boundaries, resulted in improved Al-Mg alloys creep strengths [4][5][6][7]. Because the application of rapid solidification to alloys may produce meta-stable metallic glasses with higher strength than their counterparts [8,9], the Al 12 Mg 17 alloy during quenching processes is studied in this paper.…”

Semi-Solid Consolidation Processing of Rapidly Solidified Powders for Fabrication of High Strength AZ91 Magnesium Alloys

“…In a few decades, some researchers investigated mechanical properties of rapidly solidified Mg-Al-Zn alloys consolidated by extrusion. [1][2][3][4] They reported the tensile strength of Mg-Al-Zn alloys was clearly improved compared with that of the alloys prepared by ingot metallurgy. And they clarified the strengthening of the alloys was attributed to the obtained microstructures and/or non-equilibrium structures.…”
