Problems solved by technology

[0003] The mechanical properties of materials are closely related to their actual service conditions. It is obviously not scientific and practical to use the mechanical properties of materials measured under normal temperature-weak magnetic conditions to guide the design and use of materials or structures under variable temperature-strong magnetic conditions. However, the existing traditional nano-indentation testing instruments do not have the ability to measure the mechanical properties of materials under variable temperature and strong magnetic conditions.
