Internal Friction Peaks in a Porous CuAlMn Shape Memory Alloy

Article Preview

Abstract:

Internal friction behavior of a porous CuAlMn shape memory alloy was examined. Two internal friction peaks appear at around 350 oC and 380 oC during the first heating process in the as-quenched specimen, but they disappear during the second or more heating process. Two other internal friction peaks are found at around 150 oC and 325 oC from the second heating process. Correlated mechanisms of the peaks are discussed.
