Structural Characteristics of Nickel Super Alloy INCONEL 713LC after Heat Treatment

Popis výsledku v původním jazyce

Purpose: Aircraft industry often uses nickel super-alloys for blades of jet engine turbines. This paper summarises analysis of influence of heat treatment on structural characteristics of nickel super-alloy INCONEL 713LC. Methodology: Experimental investigation castings made of commercially produced nickel super-alloy INCONEL 713LC. Material was after heat treatment subjected to detailed structural analysis with use of methods of light microscopy (LM), or scanning electron microscopy (SEM) on microscopes OLYMPUS IX71 and JEOL JSM 50A. Findings: Mode of optimum heat treatment was proposed. On the basis of obtained results it is possible to recommend a heat treatment, which would consist of heating and dwell at the temperature exceeding 1240 oC (min. 1260 oC), so that precipitates at the grain boundaries dissolve completely, with subsequent slow cooling down to the temperature of approx. 940-950 oC, so that there occurs intensive intra-granular precipitation of inter-metallic phase ?'.
