The protective performance of zeolite coating on AZ91D magnesium alloy was evaluated using potentiodynamic polarisation and electrochemical impedance spectroscopy (EIS) in 0.1 M sodium chloride solution (NaCl). Electrical equivalent circuit (EEC) was developed based upon hypothetical corrosion mechanisms and simulated to correspond to the experimental data. The morphology and …

corrosive anions for magnesium are sulphate and chloride. This paper deals with their effect at low concentrations on the corrosion behaviour of Mg and Mg based alloy (AS31 and AZ91) in
2020/8/17· Magnesium processing, preparation of magnesium ore for use in various products. In its pure form, magnesium lacks sufficient strength for most structural appliions. However, the addition of alloying elements improves its properties to such an extent that both
Development of ductile magnesium alloys is key to their use in reducing the weight of vehicles and other appliions. Wu et al. tackle this issue by determining the underlying mechanisms in unprocessed magnesium alloys. Dilute amounts of solutes enhanced certain ductility-improving mechanisms over ones that cause brittle fracture. From this, the authors developed a theory that may be helpful
A paper describing the advance was published in Nature Communiions. Using the new approach, the researchers produced welded joints with a tensile strength up to 392 megapascals.
Magnesium occurs in nature as a mixture of three isotopes: magnesium-24 (79.0 percent), magnesium-26 (11.0 percent), and magnesium-25 (10.0 percent). Nineteen radioactive isotopes have been prepared; magnesium-28 has the longest half-life, at 20.9 hours

The appliion of magnesium alloys is greatly limited because of their relatively low strength and ductility. An effective way to improve the mechanical properties of magnesium alloy is to refine the grains. As the race for better materials performance is never ending
The wear rate of the reinforced magnesium alloy metal matrices is lower than that of the unreinforced counterpart (AM60-T5 and AZ92-T6). The improved wear resistance of the composite microstructures is attributed to the presence and distribution of the ceramic reinforcement phase, which minimizes the tendency for material flow or plasticity at the surface during sliding.
Magnesium alloy AZ31B plastically deforms via twinning and slip. Corresponding to the unidirectional nature of twinning, the activity of twinning/detwinning is directly related to loading history

2016/3/22· MIT researchers have found a way to make liquid metal batteries practical and affordable. Their approach, which employs calcium, opens a host of potential variations that could make use of local resources. Liquid metal batteries, invented by MIT professor Donald Sadoway and his students a decade ago, are a promising candidate for making renewable energy more practical.
As potential hydrogen storage media, magnesium based hydrides have been systematically studied in order to improve reversibility, storage capacity, kinetics and thermodynamics. The present article deals with the electrochemical and optical properties of Mg alloy hydrides. Electrochemical hydrogenation, compared to conventional gas phase hydrogen loading, provides precise control with only

I. INTRODUCTION 3 Copper and copper alloys are widely used in a variety of products that enable and enhance our everyday lives. They have excellent electrical and thermal conductivities, exhibit good strength and formability, have outstanding resistance to
American Elements manufactures high purity magnesium-dysprosium alloy foils in numerous dimensions. Standard metal and alloy foil thicknesses range from 0.003" to approximately 2mm; materials can also be rolled down as thin as 0.001" for use as an evaporation source in microelectronics, optics, magnetics, MEMS, and hard resistant coatings.
Noise and mechanical vibrations not only cause damage to devices, but also present major public health hazards. High-damping alloys that eliminate noise and mechanical vibrations are therefore required. Yet, low operating temperatures and insufficient strength/ductility ratios in currently available high-damping alloys limit their applicability. Using the concept of high-entropy alloy (HEA
They studied the shock behaviour of several metals including ZW3—a high strength magnesium extrusion alloy (Zn 3.0, Zr 0.6—wt%). They repeatedly observed a relaxation in stress behind the shock front prior to the arrival of the release wave that they attributed to slip only occurring on the basal plane.
