STATE-OF-ART TECHNOLOGY ALLVAC 718 Plus SUPERALLOY FOR GAS TURBINE ENGINE PARTS

摘要：

Innovations on the aerospace and aircraft industry have been throwing light upon building to futures engineering architecture at the todays globalization world where technology is the indispensable part of life. On the basis of aviation sector, the improvements of materials used in aircraft gas turbine engines which constitute 50 ％ of total aircraft weight must protect its actuality continuously. Utilization of super alloys in aerospace and defense industries can not be ignored because of excellent corrosion and oxidation resistance, high strength and long creep life at elevated temperatures. The newly innovated ALLVAC 718 Plus superalloy which is the last version of Inconel 718 has been proceeding in the way to become a material that aerospace and defense industries never replace of any other material with combining its good mechanical properties, easy machinability and low cost. However because it is a newly developed superalloy, in present paper its properties including chemistry, microstructure, strengthening mechanisms, weldability and cost will be discussed and the superiority of the ALLVAC 718 plus will be addressed.
