内容記述 | The high-temperature hardness of chromium copper bar (Cr 0.7~1.3%, Cu bal.) was measured. As was expected, the hardness of Cr-Cu bar that was more strongly cold-worked showed more rapid decrease of hardness with the rise of temperature than weakly cold-worked bar. This fact shows that in preparing test-pieces for high-temperature hardness measurement it is necessary to cut the sample so as to make the effect of the cold-work due to cutting to a smallest possible degree. Quenched sample should exhibit precipitation phenomenon when annealed at about 450℃, but as far as the microphotographs (the magnification was 20000 or less) were concerned no definite proof of precipitation was obtained. | |||||
