Abstract

Abstract

Aiming at the key technology of Ti60 high temperature titanium alloy preparation by smelting process, 0A grade military granulated sponge titanium and appropriate master alloy were selected to prepare Φ310 mm large Ti60 high temperature titanium alloy ingot, via vacuum consumable arc furnace smelting. The prepared ingot has a well surface quality without defects such as cold isolation and missing edge. The alloy elements are evenly distributed in the ingot, and the impurities content and distribution are well controlled. The effects of the mixing mode of high melting point elements such as Nb, Ta, Mo and low melting point elements such as Sn, melting current and voltage on composition uniformity and defect control of the alloy ingot were systematically studied. The forgings made from the ingot through subsequent processes have met the industrial and technical requirements through mechanical properties test and ultrasonic flaw detection.
