Title:

MEMBER HAVING SEPARATION STRUCTURE AND METHOD FOR MANUFACTURE THEREOF

Document Type and Number:

WIPO Patent Application WO/2002/070762

Kind Code:

A1

Abstract:

A method for manufacturing a member having a separation structure which comprises subjecting a melt of an alloy which separates into two phases having different compositions from each other in some range of the liquid state thereof, exhibits a $g(D)T of 10°C or more wherein $g(D)T denotes the difference between the highest temperature Tc and the lowest temperature Td at which the separation into two phases is observed, and optionally exhibits the difference in volume percentages between the two phases of 5 % or more to a slip casting or to a spray cooling into a predetermined shape from a temperature of (the above Tc + 10 ° C) or higher, to thereby form a separation structure comprising two regions having different compositions from each other.
