More Information
Summary:The invention discloses a preparing method for a toughening magnetic shape memory alloy, and relates to a preparing method for the magnetic shape memory alloy and solves the problems of great brittleness, low intensity and high threshold value of driving magnetic field of the existing magnetic shape memory alloy Ni-Mn-Ga. The toughening magnetic shape memory alloy of the invention is prepared according to the following steps and then a toughening magnetic shape memory alloy Ni53Mn23.5Ga18.5Ti5 can be obtained: taking material according to mole ratios, arc melting, cleaning, heat preservation and water quenching. The magnetic shape memory alloy Ni53Mn23.5Ga18.5Ti5 prepared by the invention has the advantages of great toughness, great intensity and low threshold value of driving magnetic field.
