Abstract

The invention relates to the technical field of composite materials, in particular to a resin-based Ni-Co-Mn-In alloy composite material and a preparation method thereof. The resin-based Ni-Co-Mn-In alloy composite material consists of resin with the elastic modulus of 0.45Gpa and Ni45Co5Mn36.6In13.4 alloy with the particle size of 20-60 mum. A preparation method of the composite material comprises the following steps of: performing ball milling on a Ni-Co-Mn-In alloy material until the particle size of the Ni-Co-Mn-In alloy material is 20-60 mum, and uniformly mixing the Ni-Co-Mn-In alloy material with resin, wherein the alloy material accounts for 25-50 percent by volume of the composite material; stirring and mixing the mixture in a water bath of 60 DEG C for 20-40 minutes to obtain mixture slurry; and pouring the slurry into a mold, drying and curing to obtain a Ni45Co5Mn36.6In13.4 alloy material.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a resin-based Ni-Co-Mn-In alloy composite material and a preparation method thereof. Background technique [0002] In 2006, Kainuma et al. of the University of Tokyo in Japan discovered a new type of magnetron shape memory alloy with both large magnetically induced strain and large output stress in Ni-Co-Mn-In quaternary alloy. According to the report of the research group, for the pre-deformed 3% Ni 45 Co 5 Mn 36.7 In 13.3 After applying an 8 T magnetic field to the single crystal, a magnetically induced recovery strain of about 2.9% can be generated, and the strain is caused by the magnetic field-induced phase transformation from the martensite phase to the parent phase. By calculation, the output stress of the phase-transformed alloy is greater than 100 MPa when a 7 T magnetic field is applied, far exceeding that of the Ni-Mn-Ga alloy (2~5 MPa) developed in the...
