| Abstract Scope |
Ordering represents great opportunity for designing high temperature alloys as super-dislocations are needed to cut through ordered particles. Thus, below the critical temperature of ordering, these particles have the ability to retain strength. In this talk, we present a pathway utilizing ordered precipitates to develop Cu-based alloys that have desired conductivity as well as mechanical strength at high temperature for heat flux applications. We show that introduction of the coherent ordered particles are much more effective design approach for copper alloys in comparison to strategies like inducing nano-twins in pure fcc-Cu and introducing second phase particles. A new class of alloys that contain transition metal alloying additions like Fe and Co with further tuning by the addition of Si and Al will be demonstrated. The optimization of the alloys not only result in exceptional thermal conductivity at high temperatures but also provides opportunities for imparting good oxidation resistance. |
