Title:
METHOD FOR REMOVING INCLUSIONS FROM HIGH-TEMPERATURE ALLOY BY ELECTRON BEAM OVERHEATING DISSOLUTION
Document Type and Number:
WIPO Patent Application WO/2022/033463
Kind Code:
A1
Abstract:
Provided is a method for removing inclusions from a high-temperature alloy by electron beam overheating dissolution. The method comprises the following steps: pre-treating a high-temperature alloy raw material; and removing inclusions by means of electron beam refining and electron beam overheating dissolution, so as to obtain a high-purity high-temperature alloy cast ingot. The present invention uses the characteristics of a high vacuum and a local ultra-high temperature in an electron beam refining process, a local overheating treatment is performed on a high-temperature alloy melt, such that the in-situ dissolution and removal of small size inclusions inside the melt is achieved, and a new way for the deep removal of inclusions is provided.
