押込変形プロセス試験と引張変形プロセス試験の関連性の検討(1)

抄録

From a study of the indenting deformation process test it became clear that there were large mutual interaction effects between the heat treatment conditions of the test piece and the test conditions, and that the strength of materials is determined by the combination of heat treatment conditions and test conditions. In the present study, a high hardness level tension deformation process test was carried out and its relation to the indentation deformation process test was studied. The meanings of the S/N ratio η and the sensitivity coefficients β₁ and β₂ were clarified, and the possibility was shown of being able to establish an all-purpose evaluation method for the strength of materials by considering the strength of materials as a deformation process and applying this to both tension tests and hardness tests.
