[en] Strength and creep characteristics of molybdenum-tungsten bimetallic composition specimens prepared by reduction of tungsten hexafluoride with hydrogen have been determined in the temperature range from 20 to 1800 deg C. It is shown that at 20 deg the bimetal strength is independent of the tungsten layer thickness and is generally 45 kgf/mm². The brittle-plastic transition point is between 300 and 500 deg C. At elevated temperatures the strength and secondary creep rate characteristics of bimetallic compositions begin to be dependent on the tungsten layer thickness
