A fabricator resource receives an assembly including a first portion of material and a second portion of material. Initially, the first portion of material in the assembly may have a different modulus of elasticity than the second portion of material. The fabricator resource exposes the assembly to one or more heating/cooling cycles. Exposure of the assembly to the one or more heating/cooling cycles modifies a modulus of elasticity of the first portion of material and a modulus of elasticity of the second portion of material to desired target values (such as substantially same or different values).
