BONDING METHOD OF SINGLE CRYSTAL SUPERALLOYS WITH HIGH TEMPERATURE AND PRESSURE PROCESS

摘要

PURPOSE: A junction method for a single crystal super heat resistant alloy using a high-temperature high-pressure process is provided to improve junction characteristics, such as tensile strength and elongation ratio, through high-temperature pressing and post-thermal processing. CONSTITUTION: A junction method for a single crystal super heat resistant alloy using a high-temperature high-pressure process comprises the steps of: preparing a single crystal super heat resistant alloy, adding an insert to the single crystal super heat resistant alloy and implementing junction, and sequentially implementing high-temperature pressing and post-thermal processing. The insert is an amorphous material including a main element used in the single crystal super heat resistant alloy.
