Martensitic and inter-martensitic transformations in magnetocaloric Ni2.15Mn0.85Ga Heusler alloy
, 2021 The entropy changes in successive martensitic phase transformations in Ni-Mn-Ga Heusler alloys can be used to realize enhanced magnetocaloric properties. A detailed study of phase transformations of one such alloy, Ni2.15Mn0.85Ga (Δ Q =4900 J/kg at 343 K,

Martensitic phase transformation in TiNi [PDF]
Scientific Reports, 2019 AbstractFrom temperature dependent perturbed angular correlation (PAC) measurements (77–873 K) in equiatomic TiNi intermetallic alloy, martensitic phase transformations have been observed. Three frequency components corresponding to three different phases of TiNi have been found in the temperature range 298–873 K.

Distributions of avalanches in martensitic transformations [PDF]
Physical Review Letters, 1994 An experimental study of the acoustic emission generated during a martensitic transformation is presented. A statistical analysis of the amplitude and lifetime of a large number of signals has revealed power-law behavior for both magnitudes. The exponents of these distributions have been evaluated and, through independent measurements of the ...
