Studies on Impact Fatigue : Part IV, Impact Fatigue Tests of 0.22%C Carbon Steel under -50°C Low Temperature Atmosphere

Abstract

In the previous report, the authors had reported on the impact fatigue characteristic composed of twoaspects, i.e., strength aspect and inelastic strain behavior aspect, through a series of fatigue tests conducted with several sorts of metallic materials. In the study reported here, the investigations under low temperature atmosphere of -50°C were made using 0.22%C carbon steel, and as the result, the impact fatigue characteristic observed under the room temperature atmosphere were revealed.
