The linear elasticity was studied in a martensitic alloy Ni50Mn25Ga9Cu16. A 0.4 % linear elastic strain is obtained in the polycrystalline sample under compressive stress of 745 MPa. The elastic modulus is 186 GPa. The obtained linear elastic strain and elastic modulus are much higher than that of ternary Ni-Mn-Ga martensitic alloys.
The compressive stress-strain curves of Ni50Mn28Ga22, Ni50Mn25Ga22Cu3 and Ni50Mn25Ga9Cu16 alloys. The inset shows the enlarged curves of Ni50Mn28Ga22 and Ni50Mn25Ga22Cu3 alloys.
