摘要

Ni_50.5Mn₂₅Ga_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.
