Cladding of Mg alloy with Zr based BMG Alloy

In the present work, an attempt has been made to clad AZ31 magnesium alloy with Zr-based bulk metallic glassy alloy (Vit-1), by casting method. The interface studies conducted using SEM-EDS line scan indicate that a good bond is formed at the clad interface of Zr and Mg. And the mechanism involved is discussed herein.110Ysciescopu

Al-TiH2 Composite Foams Magnesium Alloy

The work presented here in describes the synthesis of aluminum based titanium-hydride particulate composite by casting method and its foaming behavior of magnesium alloy. Results obtained indicate that the Al-10TiH(2) composite can be synthesized successfully by casting method. Further, results also reveal that closed-cell magnesium alloy foam can be synthesized by using Al-10TiH(2) composite as a foaming agent.111Ysciescopu

Al-Ti-C-Sr master alloy-A melt inoculant for simultaneous grain refinement and modification of hypoeutectic Al-Si alloys

Present article is focused on the microstructural features of Al-Ti-C-Sr master alloy, an inoculant for simultaneous grain refinement and modification of hypoeutectic Al-Si alloys. This master alloy is basically a metal matrix composite consisting of TiC and Al(4)Sr phases formed in situ in the Al-matrix. TiC particles initiate the refinement of primary alpha-Al through heterogeneous nucleation in molten hypoeutectic Al-Si alloy, while Al(4)Sr phase dissolves in molten Al-7Si alloy enriching the melt with Sr, which eventually leads to modification of eutectic silicon during solidification of the Al-7Si alloy casting. Thus present master alloy serves in both ways, as a grain refiner and a modifier for hypoeutectic Al-Si alloys. (C) 2009 Elsevier B.V. All rights reserved.
