[0050] The content of the present invention will be described in further detail below through specific examples. Unless otherwise specified, the raw materials, reagents or devices used in the examples can be obtained from conventional commercial channels, or can be obtained through prior art methods. Unless otherwise specified, experiments or testing methods are conventional methods in the art.
[0051] Taking the detection of carbide content in P92 heat-resistant steel tempered at different times as an example, the detection method of the embodiment of the present invention will be described below.
[0052] In order to illustrate that the tempered samples contain carbides, the microscopic morphology of the samples tempered at different times was observed by scanning electron microscopy (SEM). P92 steel samples for comparison. attached figure 1 Shown is the scanning electron micrograph of carbide-containing P92, with figure 2 Shown is the SEM image of carbide-free P92.
