Dieringa H., Maier P., Fechner D., Bohlen J., Kainer K.U. Present and Future of Magnesium Alloys in our Civilization
This paper gives a general overview on the application of magnesium alloys during the last decades, the present and an expectation of future development. Alloy development with an emphasis on improvement of strength and creep resistance at elevated temperatures is described as well as development of casting techniques for applications of magnesium alloys. The increasing need of light weight construction in automotive industry in order to save natural energy resources can obviously been seen in the development of petrol prices during the last years. Magnesium alloys as the lightest construction metal shows a great potential for the use in automotive and aeronautical application because the requirements for weight saving solution in the next decades will increase significantly.
Sohn K.Y., Kang M.Ch., Kim K.H. Research and Development, Applications of Magnesium Alloys in Korea
This paper reviews the recent research and development, demand, and applications of magnesium alloys and outlines the prospects of magnesium industry in Korea. Magnesium alloys research in Korea has become active in the last a few years. The research field covers many aspects of magnesium alloys including new applications. Magnesium alloys demand in Korea has been growing continuously for the last ten years. The applications have been limited to the 3C (cameras, computers, and communications) components initially, but many magnesium diecasters tend to reduce the 3C production volume lately, because of high standards in surface finish and large production cost. Researches to develop a technology producing wrought products such as extrusions or sheets at low costs have been conducted. The use of magnesium seat frame would be limited to luxury cars initially, but be expanded to mid-sized cars, resulting in large demand of magnesium alloys in a few years.

Boldin A.N. et al. Effect of Carbon Equivalent on the Formation of Gas Porosity in Iron Castings
As a result of investigations, dependence of cast iron's susceptibility to gas porosity formation on carbon equivalent has been determined. The obtained dependence allows determining an alloy's susceptibility to gas porosity formation at the stage of designing the iron casting production process and outlining technological measures to prevent it.
Medvedev K.A. et al. Investment Casting of Corrosion-Resistant Steels with Solidification under Pressure
The article brings results of experimental work to make parts from corrosion-resistant steels 12Х18Н9ТЛ and 10Х18Н11БЛ by investment casting with solidification under pressure (ICSP) and methods of designing the process using LVMFlow. It has been shown that mold filling from the bottom and solidification of castings under pressure ensure an increase in the density of 12Х18Н9ТЛ steel as compared to the serial process from 7,800 to 8,100 kg/m3 and enhancement of all mechanical properties. The quality of castings produced by ICSP meets the NTD requirements for forgings and pressed-and-welded components, which allows using ICSP to make especially critical castings for power machine building.
