The grain size of as-extruded AZ91 magnesium alloys was refined to 12.31 µm from 21.41 µm by recrystallization annealing. The vacuum diffusion welding of as-annealed AZ91 magnesium alloys was researched. The results showed that the maximum shear... see more

Manganese-bismuth (MnBi) mechanical alloys have been under development for novel permanent magnets without rare-earth elements. The ball-milling of bismuth (III) oxide and manganese powders in this work leads to soft magnetic MnBi alloys with rod-like MnO... see more

The grain refinement and its effect on the mechanical properties of AZ31 magnesium alloys were investigated. The grain refinement was conducted using one of the severe plastic deformation methods, warm constrained groove pressing (CGP) technology. The eff... see more

The improvement of mechanical properties of magnesium alloys nowadays is very important, because of the variety of industrial applications. For this goal, the number of casting techniques and further treatments were developed. Among the continuous casting... see more

The magnesium and magnesium alloys has applied widely in different industrial aspects in Vietnam in the modern life. Especially, the products from magnesium alloys implementing in the automotive have increased rapidly since the car elements tend to be gen... see more

The study was performed on alloys with a carbon content of 0.37-0.57% (wt.), silicon 0.23-0.29% (wt.), manganese 0.7-0.86% (wt.), the rest– iron. To determine the phase composition of alloys used microstructural, microanalysis and X-ray analysis. In ... see more

The article addresses the relevant issue of determining the thermotechnical characteristics of the fire-extinguishing powder for thermal insulation of the fire center of materials based on magnesium alloy chips to prevent fire development and propagation ... see more

The coating of nicotinic acid (NA), sodium fluoride (SF) and sodium fluoric - nicotinic acid (SF-NA) deposited from a sodium fluoric solution with subsequent treatment in nicotinic acid on magnesium alloy AZ31 has been investigated. The corrosio... see more
