Stabilization of L12 structured Cr3Cu precipitates in a Cu-4.06Cr-1.25Nb alloy with high high-temperature strength

Stabilization of L12 structured Cr3Cu precipitates in a Cu-4.06Cr-1.25Nb alloy with high high-temperature strength

Stable L12 structured Cr3Cu precipitates were determined in a Cu-4.06Cr-1.25Nb alloy rather than b.c.c. structured Cr precipitates by transmission electron microscope (TEM) and three-dimension atom probe tomography (3DAP) at 450 oC. The precipitation sequence of the studied alloy aged at 400 oC was...
