Abstract

The invention belongs to the field of amorphous alloys, and more specifically, relates to a method for calibrating the internal temperature field of amorphous alloy prepared by spark plasma sintering. First, the part required for temperature field calibration inside the bulk amorphous alloy sample obtained by spark plasma sintering is cut into a series of small amorphous alloy samples, and the isothermal crystallization treatment is performed to obtain the crystallization time of different parts of the sample. An annealing-isothermal crystallization experiment is performed on the adopted amorphous alloy powder at different annealing temperatures, and the functional relationship between the annealing temperature and the crystallization time is obtained. The crystallization time of different parts inside the amorphous alloy sample is substituted into this functional relationship, the temperature distribution during the temperature holding stage during the sintering of different parts inside the amorphous alloy sample can be obtained.
