鋼材料特性に与える温度変化の影響

抄録

The factors which affect the material test results, test conditions (tensile speed, temperature), the test piece shape (cross-sectional area, gauge length) can be considered such. In this study, the change in temperature was studied material test results. In particular, the temperature setting were examined plus. 12 ℃ and minus 30 ℃ The test results of negative 30 ℃ for plus. 12 ℃ is with or without a hole. yield stress, tensile strength was increased.
