Abstract
A process includes agitating at least one core of a core alloy together with a braze binder to form at least one coated core comprising the at least one core coated with a first layer of the braze binder. The process also includes agitating the at least one coated core together with a powder composition comprising a first metal powder of a first alloy and a second metal powder of a second alloy to form a green preform having a first powder composition layer of the first alloy and the second alloy. The process further includes sintering the green preform to form at least one hybrid pre-sintered preform. A green preform includes a core, a first layer of a braze binder coated on the core, and a powder composition coated on the first layer. A hybrid pre-sintered preform includes a core and a first layer sintered to the core.
