"In-situ mechanical testing new technology and instrument development and manufacturing" passed acceptance

According to news from the Ministry of Science and Technology, the Ministry of Science and Technology recently conducted a high-tech research and development center of the Ministry of Science and Technology on the development and manufacture of new technology and equipment for cross-scale in-situ mechanical testing of the National High-Tech Research and Development Program (863 Program). Technical acceptance.

It is reported that the project was launched in June 2012 and led by Jilin University. After more than three years of technical research, the research team has achieved breakthrough in accuracy calibration technology for in-situ test instruments, and has made significant progress in the design, manufacturing, and calibration of testers. Compared with the traditional material mechanics performance test technology used by other testers, the in-situ mechanical measurement instrument developed by this project can be combined with Raman spectroscopy and metallographic microscope and other material performance characterization techniques to achieve accurate testing.

At present, this topic has broken through the goal of industrialization of key technology engineering and achieved the transformation of patent achievements. Six types of 17 instruments, including indentation/sculpting, tensile/compression, shearing, bending, torsion, and tension-torsion compounding, which were developed in this project, have filled the gaps in the related fields of instruments in China. The results of this project have been applied and promoted in more than 20 universities and research institutes in China.

At the acceptance meeting, the expert group heard a report from members of the R&D project team and believed that the project had achieved a number of key technologies for micro-nano measurement, developed a series of measuring instruments, and achieved the expected goals of project implementation. Agree to pass the acceptance.
