Abstract
Methods are generally provided for forming a multi-metallic component. The method can include: positioning a nickel-based layer between an iron-based alloy and a nickel-based alloy and applying heat and pressure to the iron-based alloy and a nickel-based alloy such that the nickel-based layer forms a diffusion bond region. The nickel-based layer comprises greater than 50% by weight nickel, and the iron-based alloy, the nickel-based alloy, or both is in a powder form. The diffusion bond region is between a first region comprising the iron-based alloy and a second region comprising the nickel-based alloy to form the multi-metallic component.
Claims20
A method of forming a multi-metallic component, the method comprising:
- positioning a nickel-based layer between an iron-based alloy and a nickel-based alloy, wherein the nickel-based layer comprises greater than 50% by weight nickel, and wherein the iron-based alloy, the nickel-based alloy, or both is in a powder form;
- and
- applying heat and pressure to the iron-based alloy and the nickel-based alloy such that the nickel-based layer forms a diffusion bond region between a first region comprising the iron-based alloy and a second region comprising the nickel-based alloy to form the multi-metallic component.
A unitary multi-metallic component, comprising:
- an iron-based alloy defining a first region of the unitary multi-metallic component;
- a nickel-based alloy defining a second region of the unitary multi-metallic component;
- and
- a diffusion bond region extending into the iron-based alloy and the nickel-based alloy to join the first region to the second region within the unitary multi-metallic component.
