Preparation and Mechanical Behavior of Mg-Based Bulk Metallic Glasses and their Matrix Composite司颐Department of Applied Chemistry, Liaoning Petrochemical Vocational and Technology College摘 要:Mg87-xCuxDy13(x=22,27,32) bulk metallic glasses (BGMs) with a diameter of 6-8 mm and in-situ Mg phase reinforced Mg70Cu17Dy13 BMG matrix composite with a diameter......
that the Mg-8Li-3(Al-Si) alloy consisted of strip-like α-phase and matrix β-phase. There were some small white granular precipitates existed on the surface. The distribution of Al was more uniform (Fig. 4(c.... To understand the interference with the matrix, a bare spherical precipitate in the annealed Mg-12Li- 3(Al-Si) alloy was analyzed by TEM, as shown in Fig. 7. The EDS spectrum (Fig. 7(b)) and SAD......
