The Properties of the Highly Heat-Resistant EP487 Alloy (Svoistva Vysokozharo Prochnogo Splava EP487),

Abstract : The heat resistant properties of the EP487 (KhN60MBT10) alloy are investigated. The mechanical properties of specimens of this alloy are shown graphically and it is shown that an increase in the molybedenum content in the alloy by specified amounts raises the resistance to plastic deformation and restricts the region of high plasticity to a relatively narrow temperature range. The heat treatment conditions are outlined which result in the most favorable levels for alloy mechanical properties. A tendency toward the formation of extra-axial liquefaction non-uniformities is reduced by the employment of electroslag remelting.
