Effect of Ca addition on the changes in morphology of hypoeutectic Mg–1.15Si alloy has been studied. The addition of Ca has resulted in morphological changes in a-Mg halos by refining it from coarse dendrites to finer shape ...

Magnesium, being a lightweight and having high specific strength and modulus is an attractive structural material for automobile manufacture to replace steel, cast iron and even aluminium- based alloys in many components ...

This study aims to investigate the dry sliding wear behaviour of pure Mg, different hypo (Mg-0.5, 0.7, 1.15 wt% Si) and hyper (Mg-2, 4, 6, 8 and 10 wt% Si) eutectic Mg-Si alloys prepared using the gravity casting method. ...

This article focuses on the grain refinement and ageing behavior of AZ91 Mg alloy inoculated with charcoal. The results show addition of 0.2 wt% charcoal has made considerable grain refinement in the AZ91 Mg alloy by ...

The ageing behavior of AZ91 alloy containing 2 wt.% lead is investigated. The results show that addition of Pb suppresses the discontinuous precipitation and thereby slows down the ageing kinetics. Even though the peak ...

Effect of Pb and Sb additions on the precipitation sequence and ageing kinetics of AZ91 alloy has been studied using the differential thermal analyzer, optical microscopy and scanning electron microscopy. The precipitation ...

Effects of Si and Sb additions on the ageing behavior of AZ91 alloy have been investigated. Additions of Si and Sb lead to the formation of thermally stable Mg2Si and Mg3Sb2 intermetallic phases, respectively, which are ...

Improving the mechanical properties especially the high temperature properties of Mg-Al Mg alloy is a challenging task for the researchers. The mechanical properties of these alloys are highly sensitive to the microstructure ...

The flow curve is constructed by flow stress data obtained from compression test conducted at different temperature and strain rate. Accurate flow stress model is crucial for investigating magnesium alloys deformation ...

The grinding cost of metal matrix composite materials is more due to low removal rates and high rates of wear of super abrasive wheels. This electrolytic in-process dressing (ELID) technique uses a metal-bonded grinding ...
