JOINT STRUCTURE OF CERAMICS DISPERSED IRON GROUP ALLOY AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a joint structure of ceramics dispersion strengthening alloy joined by a friction stir welding method that can maintain the superior high temperature characteristic originally possessed by this alloy, and also to provide the manufacturing method of the structure as well as its use. SOLUTION: The invention refers to the joint structure joined by friction stir welding method between ceramic particle dispersed iron group alloys or between such alloy and a non-ceramic particle dispersed iron group alloy, particularly to the welding performed in the temperature range where the ductility of the ceramic particle dispersed iron group alloy is maximized by the friction stir welding method.
