Information × Registration Number 0202U000565, 0101U002984 , R & D reports Title Research of the high temperature (1100oC and is higher) viscous intergranular of fracture cast Cr-Re alloys, optimization of structure and melt of qualitative samples of preparations for hybrid composites popup.stage_title Head Pysarenko Volodymyr Oleksijovych, Registration Date 13-02-2002 Organization I.N.Frantsevich Institute for Probmens of Materials Sciences Ukrainian Academy of Science popup.description2 It has been worked out of reception of burder by a method of power metallurgy and her desgassing, wich has allowed to lower a level of carbon in burder from 0,25wt.% up to 0,01wt.%. It has been smelted the reserch samples of Cr-Re alloy. With the help of the modifier has been turned out well to improve the foundry properties of an alloy and to pour vetall in chill, thus the size of a grain has descreased almost in 100 times. The creftion of small crystalline structure alloys to avoid ductiliting intergranular fracture in the field of high temperatures. It has carried out structural reserches of cast sample with the help metallography, raster electronic microscope and OGE- spectroscope.
