High-throughput preparation method and device for gradient thermal deformation and gradient heat treatment

The invention discloses a high-throughput preparation method and device for gradient thermal deformation and gradient heat treatment. The method comprises the following steps that S1, a heating resistance wire is started, and when the heating resistance wire is heated to a preset temperature, a blank is pressed into a trapezoidal table mold through a pressing head; S2, the heating resistance wire is turned off, and heating is stopped; S3, a water source, a gas source or an oil source is started, and is sprayed and pressed into the lower end of the blank, the blank is subjected to heat dissipation from top to bottom in a heat transfer manner, and the cooling speed is gradually increased; S4, when the blank is cooled to the preset temperature, the blank enters an ejector rod, and the blank is ejected out of the bottom of the trapezoidal table mold through the ejector rod; and S5, a grain gradient distribution structure finished product is prepared. According to the high-throughput preparation method, gradient thermal deformation and gradient heat treatment of a metal material are effectively achieved, the metal material with grain gradient distribution, second phase gradient distribution and performance gradient distribution can be efficiently obtained, and high-throughput preparation and processing of a metal sample are achieved.
