Description

technical field [0001] The invention relates to a microwave high-throughput alloy preparation device and method, and belongs to the technical field of microwave high-throughput alloy preparation. Background technique [0002] Heat treatment process refers to the technology in which solid metal materials are heated at high temperature, cooled after heat preservation, so as to change the surface structure and internal chemical composition of the material to achieve the required performance. Oxidation and decarburization will occur when the workpiece is exposed to air during the heating process of the metal, which has a great influence on the surface properties of the parts after heat treatment, so the metal is usually heated in a controlled atmosphere or protective atmosphere, molten salt and vacuum. Heating temperature is an important process parameter in the heat treatment process. Selecting and controlling the heating temperature is an important issue to ensure the quality ...

AI Technical Summary

Problems solved by technology

This method processes and tests one sample each time, and the efficiency of heat treatment is low, which leads to a greatly increased cycle of research and development of materials, and high research and development costs

[0004] The existing material heat treatment research can only be carried out under one temperature condition at a time, and only one sample or one alloy can be processed at each temperature, which has low efficiency and high cost, mainly because of the following three technical defects :

[0005] (1) The experimental environment cannot guarantee a uniform heat treatment temperature field

The heat treatment furnace is generally heated by resistance. Due to the large space in the furnace, the temperature field in the furnace is not uniform, and the heating effect of the sample in the furnace is inconsistent, which seriously affects the uniformity of the heat treatment structure and the accuracy of the heat treatment process parameters.

[0006] (2) The heat treatment temperature control is single, and the temperature measurement method is backward

The current heat treatment method can only try to study the microstructure and properties of the material under one temperature condition at a time, which makes the optimization and selection of heat treatment temperature control parameters inefficient, and the single-point temperature measurement mode cannot meet the high-efficiency preparation.

[0007] (3) The size of the heat treatment sample is large, which increases the research and development time and cost

The size of the sample used in the experiment is relatively large, resulting in a slow and time-consuming heating process; in addition, repeated testing of the heat treatment process parameters requires the consumption of a large amount of materials, resulting in high R&D costs
