Optimum Alloy Size Selection The simplest example of an optimised size selection is the choice of a round bar that is closer in cross-sectional diameter to the final component (see diagram below). Two through-cost savings are made: there is less machining required on the bar so machining through-costs (operator time and tool wear etc.) is lower and the scrap though-costs are lower because less
6/7/2018· To improve the corrosion resistance and wear resistance of electroless nickel-phosphorus (Ni-P) coating on magnesium (Mg) alloy. Ni-P-Al2O3 coatings were produced on Mg alloy from a composite plating bath. The optimum Al2O3 concentration was determined by the properties of plating bath and coatings. Morphology growth evolution of Ni-P-Al2O3 composite coatings at different times was …
Taguchi’s robust design method can be used to analyze optimal heat treatment parameters for the aluminum copper magnesium alloy described in the paper. The current study, it is observed from taguchi analysis that hardness value is optimized at 1.5% Mg addition, 5hr ageing duration, 5300c solution temperature and with ageing temperature of 1700c.

The effects of the ultrasonic treatment on microstructures,density and mechanical properties of AZ80 magnesium alloys were investigated with OM,SEM and Archimedes principle.The results show that after the ultrasonic treatment at 610 ,the grain size and
Chromium is a common addition to many alloys of the aluminum-magnesium, aluminum-magnesium-silicon, and aluminum-magnesium-zinc groups, in which it is added in amounts generally not exceeding 0.35%. In excess of these limits, it tends to form very coarse constituents with other impurities or additions such as manganese, iron, and titanium.
Magnesium is the lightest metal engineering structural material having a density of only 1.8 g / cm 3, 1/4, 2/3 aluminum steel. Due to the quality of light alloy magnesium, specific strength and stiffness ratio, good damping, also has excellent cutting performance

The current work investigated the effect of shot peening (SP) on high cycle fatigue (HCF) behavior of the hot-extruded ZK60 magnesium alloy. SP can significantly improve the fatigue life of the ZK60 alloy. After SP at the optimum Almen intensities, the fatigue strength at 107 cycles in the as-extruded (referred to as ZK60) and the T5 aging-treated (referred to as ZK60-T5) alloys
The base alloy 5052 is generally recognized as the maximum magnesium content base alloy that can be welded with a 4xxx series filler alloy. Because of problems associated with eutectic melting and associated poor as-welded mechanical properties, it is not recommended to weld material in this alloy series, which contain higher amounts of magnesium with the 4xxx series fillers.
