Internal friction behavior of Ni50.5Mn25Ga24.5 alloy with cellular microstructure

Ni 50.5 Mn 25 Ga 24.5 alloy with cellular microstructure was fabricated. The effect of the cellular microstructure on the internal friction (IF) behavior associated with martensitic transformation (MT), premartensitic transformation (PMT) and twin boundary motion (TBM) was investigated. Compared wit...

Description
Summary:Ni 50.5 Mn 25 Ga 24.5 alloy with cellular microstructure was fabricated. The effect of the cellular microstructure on the internal friction (IF) behavior associated with martensitic transformation (MT), premartensitic transformation (PMT) and twin boundary motion (TBM) was investigated. Compared with conventional Ni–Mn–Ga alloys, the temperature span of the IF MT peak is significantly expanded, the IF PMT is weakened, and no IF TBM is detected. Both IF MT and IF PMT in the cellular microstructure exhibit unique frequency dispersion feature which has never been observed in conventional Ni–Mn–Ga alloys. The effect of point defects associated with the cellular microstructure is considered to understand the observed results.
