Claim:
1. A method of forming an implantable orthopedic construct that includes a porous surface layer, comprising: providing or obtaining an initial version of an orthopedic construct that includes an underlying metal substrate of a first mass metallurgically bonded to a porous metal surface layer by applying clamping pressure to and heating the underlying metal substrate of the first mass and the porous surface layer; and reshaping the initial version of the orthopedic construct into a subsequent version of the orthopedic construct which includes removing mass from the underlying metal substrate of the first mass to form an underlying metal substrate of a second mass, wherein the underlying metal substrate of the first mass is significantly more massive than the underlying metal substrate of the second mass such that the underlying metal substrate of the first mass will exhibit greater thermal expansion when heated than would the underlying metal substrate of the second mass.
