MECHANICAL PROPERTY MEASUREMENT DEVICE, MECHANICAL PROPERTY MEASUREMENT METHOD, MATERIAL MANUFACTURING FACILITY, MATERIAL MANAGING METHOD, AND MATERIAL MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/256443
Kind Code:
A1
Abstract:
Provided are a mechanical property measurement device and mechanical property measurement method capable of accurately measuring mechanical properties by physical quantities. Also provided are a material manufacturing facility and material manufacturing method capable of improving the manufacturing yield of a material as a result of using the capability of accurately measuring mechanical properties by physical quantities. Additionally provided is a high-quality material as a result of using the capability of accurately measuring mechanical properties by physical quantities. A mechanical property measurement device (100) comprises: a physical quantity measurement unit (5) that measures a plurality of physical quantities of a measurement target which includes a material and a film on the surface of the material; a mechanical property calculation unit (82) that uses a plurality of calculation models for calculating the mechanical properties of the material and at least two of the plurality of measured physical quantities so as to calculate the mechanical properties of the material for each of the plurality of calculation models; and a selection processing unit (81) that selects, on the basis of the at least two of the plurality of physical quantities, one from the plurality of calculated mechanical properties as the mechanical property of the material.
