Abstract
Tendencies in the development of electroslag technologies and production of high-alloy steels and alloys using EST methods have beeb analyzed. Steady tendencies in the growth of production of electroslag metal by 5-6 % per year over recent 10 years and for the nearest future are shown. Feasibility of EST application in the production of superalloys, titanium, intermetallics and bimetals is discussed
Keywords: electroslag remelti12g, superalloys, titanium, bunetals, titanium aluminide, nanoteclmologies
