Abstract: A device for measuring short-wavelength characteristic X-ray diffraction based on array detection, and a measurement and analysis method based on the device are provided. An array detector of the device only detects and receives a diffraction ray which is diffracted by a material of a to-be-measured part inside a sample and passes through a through hole of a receiving collimator, and rays passing through a positioning hole. The to-be-measured part inside the sample is placed at the center of the diffractometer circle of the device. The method is performed with the device. With the present disclosure, a diffraction pattern of a part inside the sample with a centimeter thickness, i.e. Debye rings, can be rapidly and non-destructively measured, thereby rapidly and non-destructively measuring and analyzing crystal structures, and its crystal structural change of the part inside the sample, such as phase, texture, and stress.

Abstract: The disclosure relates to a method for preparing Ti(C,N)-based superhard metal composite materials, with Ti(C,N) powder and (W,Mo,Ta)(C,N) powder as main raw materials and Co powder as binding phase for preparation, thereby obtaining a material in which a microstructure is a double-core rim structure that has both a black core rim and a white core rim. The material has a complete and evenly distributed double-core rim structure. In the condition that the ensured hardness of the material is not reduced and even slightly increased, the toughness of the material is significantly improved, wherein the fracture toughness of the material is in the range of 11.3 to 12.5 MPa·m1/2.
