Information × Registration Number 0201U006242, 0100U000870 , R & D reports Title Defeloment of theoretical bases of grainrefinement of casting magnesium alloys by refractory ultra-particle scandium-containing compounds with the of improving treirs mechanical properties. popup.stage_title Head Chernega Dmytro Fedorovych, Registration Date 17-12-2001 Organization National Technical University of Ukraine "Kiev Polytechnic Institute", Mechanical Building Institute, chair Resistance of Materials popup.description2 3. The work has made in order to defelop theoretical basements of the foundry magnesium alloys modifying, mainly of the magnesium-aluminium-zinc system, by refractory scandium containing substances and creation on the basis of scientific researches of effective technology of these alloys, what has been fused with aid of secondary fusion mixture. The fusion melt alloys (ML3, ML5, ML6) processing by scandium containing fluxing material, permits to essential grow their mechanical features. There are temporary break resistance growing by 15-20 %, and lengthening- in 1,2-1,4 times, at simultaneous downturn of the cost of productions by 10 %, due on economy of primary materials.
