Abstract

Abstract: In order to explore the heat treatment process of the alloy tube, the effects of different heat treatment parameters on microstructure and mechanical properties of Inconel 617 alloy tube were studied by means of optical microscope (OM), hardness and tensile test at room temperature, etc. The alloy was characterized by optical microscope, and the variation rule of the grain size of the alloy was analyzed when the temperature between 1120-1200 ℃ and the holding time was 10 and 30 min, respectively, and the dynamic model of grain size growth was established. The results show that the average grain size increases with the increase of temperature, and there are more twins in the grain. At the same time, with the continuous increase of heat treatment temperature, the change trend of hardness and tensile strength of the alloy is the same, both of them show a decreasing trend with the increase of temperature. The elongation of the alloy increases with the increase of temperature. The apparent activation energy of grain boundary migration of the Inconel 617 alloy is 651.82 kJ/mol.
