in this study, attempts were made to recovery the used turbine blades made up of inconel738 by electro slag remelting (esr) method. using an appropriate slag and addition of metallic aluminum, the original composition was maintained and the amount of oxygen, hydrogen and nitrogen remained in the acceptable level. in order to explore the effect of remelting with esr on the microstructure, tensil...

In the present study, M2 high speed steels were fabricated by using electro-slag rapid remelting process. Carbide structure was analysed and the fracture toughness and hardness were also measured after austenitization treatment at 1190 and 1210C followed by tempering treatment at 535C for billets with various diameters from 16 to 60 mm. Electro-slag rapid remelting (ESRR) process is an advanced...

This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...

is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...

This study focuses on the impact of solidification inclusion morphologies in different sizes production-scale electro-slag remelting (ESR) and under a protected pressure-controlled atmosphere, (PESR), ingots, common martensitic stainless steel grade. The investigation has been carried out to increase knowledge change during ESR PESR remelting. In order optimize process routes for grades, it is ...
