Chromium and chromium-base alloys are promising materials for a manber of areas of technology as the restdt of their unique properties. However, their increased btfttleness at tem-peratures below O. 3 Tmelt ( ~ 630 °C) and, consequently, their low impact strength at Iooltl temperature retard their use and make it necessata' to conduct in vestigations for the purpose of determining the conditions of use of these matelqals. This atvicle presents the results of impact tests of chromium and its alloys at temperatures zip to 1100°C. Special attention was devoted to the test method for Hw purpose of obtaining reliable results.Khr-0 pure chromiunl (0.0081% O, 0.0041% N), Khr-3 alloy (0.45% Fe, 0.44% La), which has production plasticity, and VKhl-5V heat-resistant alloy (2 % V, 0.092 % N, 0.6% Ce) were investigated. Tile basic charge material m melting of them was 99.95% pure leRKh electrolytic refined chromium. The 8 and 25 kg chromium and chromium-base alloy ingots were melted in water-cooled copper molds with diameters of 70 and 120 ram, respectively. A protective atmosphere of especially,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
