Abstract

An article (20; 300) comprises a first portion (22; 301) comprising a first alloy and a second portion (24; 303) comprising a second alloy that is metallurgically bonded to the first portion to form a monolithic article. The metallurgical bonding involves the application of an electrical current across the bond line (26) and results in a retention of a metallurgical structure of the first portion (22; 301) and of a metallurgical structure of the second portion (24; 303) immediately adjacent to a bond line (26). The first portion (22; 301) has a first dominant property and the second portion (24; 303) has a second dominant property. The first dominant property is different from the second dominant property. The first dominant property is selected to handle operating conditions at a first position of the article (20; 300) where the first portion (22; 301) is located and the second dominant property is selected to handle operating conditions at a second position of the article (20; 300) where the second portion (24; 303) is located.
