Abstract

The results of development the technological process of obtaining casting parts «diffuser» for gas turbine engines in the conditions of machine-building enterprise are presented. Nondestructive testing was carried out to identify metallurgical defects on castings, and tensile and long – term strength tests were carried out to determine mechanical properties. The conclusion is made that the fulfilled technological process of casting of shaped parts from VZh159 superalloy allows to recommend it to serial production for production of shaped castings of details of aircraft engines.
