Abstract
We present an elastic matrix for 10M Ni-Mn-Ga-Fe martensite with incommensurate (IC) lattice modulation and immovable twin boundaries (TBs). The modulation vector qIC=0.4136·q110 for the investigated IC state is located between the values for the commensurate (C) state, qC=0.4·q110, and the maximum value for IC 10M structures reported in various studies qICmax=(3/7)q110=0.4286·q110. The elastic matrix obtained for the IC modulated lattice differs in certain components, especially those related to shear in a/b system, as well as the corresponding Young’s moduli, compared to the values reported for martensite with C modulation. This study presents experimental evidence of internal stability in IC modulated structure, subjected to stresses that significantly exceed the a/b twinning stress (TS) observed in C structures. This study examines the observed differences in the small stress response of C and IC lattices, emphasising the roles of highly mobile a/b TBs and lattice instability near TBs in the C case.
