Abstract

Casting methods and articles (100) are disclosed wherein a molten first material (108) is introduced into a mold (200) which distributes the first material (108) to form a first region (102) of the article (100) where it is subjected to a first condition suitable for growing a first grain structure, forming the first region (102) of the article (100). A molten second material (110), compositionally distinct from the first material (108), is introduced into the mold (200) to form a second region (104) of the article (100). A hybridized material (112) is formed by intermixing a first portion (500) of the second material (110) with the second portion (302) of the first material (108). A second portion (502) of the second material (110) is subjected to a second condition suitable for growing a second grain structure distinct from the first grain structure, forming the second region (104) of the article (100). The first region (102) and the second region (104) are integrally formed as a single, continuous article (100) with a hybridized region (106) formed between.
