Mechanical and Magnetostrictive Properties of Fe—Doped Ni52Mn24Ga24 Single Crystals
摘要
To improve the magnetic and mechanical properties of a Heusler alloy of Ni52Mn24Ga24,iron was doped with some cotents,Single crystals of the pseudoquaternary Heusler alloy of Ni52Mn8Fe15Ga24 have been synthesized for mechanical and magnetostrictive measurements.The magnetostriction loops and stress-strain curves were measured under different coupled magnetic-mechanical loads.The experimental results show that the brittleness of the sample is clearly improved and Yong's modulus of 13.7GPa is obtained in the [001] direction due to the part substitution of Fe for Mn.Furthermore,the toughness and Vickers hardness of the sample are also given by use of the indentation technique.
