Title:
RELATING TO ALLOY STRUCTURE AND METHOD FOR PRODUCING ALLOY STRUCTURE.
Document Type and Number:
WIPO Patent Application WO/2016/013496
Kind Code:
A1
Abstract:
Provided is an alloy structure having a highly uniform elemental composition and mechanical strength distribution, having good high-temperature strength and corrosion resistance, and having arbitrarily defined shape dimensions. This alloy structure contains Al, Co, Cr, Fe, and Ni within an atomic concentration range of 5-30 at%, inclusive, each, wherein the difference between the atomic concentrations of at least four of the aforementioned elements is within the range of less than 3 at%, and a columnar crystal formed by dissolving the aforementioned five elements constitutes the main crystal.
