Heat treatment device and heat treatment method for rapid heating in pulsed magnet field

Abstract

The invention relates to a heat treatment device and a heat treatment method thereof for rapid heating in a pulsed magnet field. The heat treatment device comprises a magnetic field coil, a heating system, a sealing system and a feeding device; the heat treatment method can achieve the heat treatment of the pulsed magnet field under vacuum atmosphere or specifical atmosphere, and adopts the principle that the pulsed magnet field is applied during the heat treatment process and the organizational structure of material is changed by utilizing the interaction of material and the magnet field as well as the anisotropy characteristic of the magnet field so as to obtain needed performances. A feeding rod is utilized to send samples to the position around a central armored thermocouple of a Quartz furnace tube, and the metal feeding rod achieves low heat capacity and low heat absorption, so that preset temperature can be achieved rapidly and heat preservation can be performed for a pluralityof hours. The heat treatment device and the heat treatment method thereof change the present situation that the samples can only be heated slowly in the heat treatment of the magnet field, and improve the efficiency of the heat treatment of the magnet field.
