　View Summary

Surgery, radiation therapy, and chemical therapy have been reported as the main treatments for cancer, which is one of the deadliest reported diseases. However, because of the high invasiveness of patients, cancer hyperthermia has been studied as a non-invasive treatment. Hyperthermia uses a difference in thermal tolerance between normal and cancer cells and provides an affected part thermal stimulation to kill cancer cells selectively. To develop effective conditions for hyperthermia, an in vitro study to evaluate the thermal tolerance is required. However, because the existing cell culture vessels cannot control the culture temperature, genuine thermal tolerance of cells cannot be investigated appropriately. To reveal the critical temperature proper for hyperthermia, we developed a culture device controlling culture temperature. With the developed device, culture temperature was regulated considerably more quickly than the conventional method with the existing vessels, which enabled us to study the thermal tolerance of cells appropriately. For the control of culture temperature, the device has a titanium culture substrate, where a Peltier element is adhered. Because the biocompatibility of the device was confirmed, the difference in thermal tolerance between normal and cancer cells was investigated using the developed device as well as normal human dermal fibroblasts and Michigan Cancer Foundation-7 as model cell species. Therefore, it was confirmed that cancer cells were more sensitive to thermal stimulation than normal cells, which was qualitatively consistent with previous studies. Thus, our developed device can be used to investigate the thermal tolerance of each cell species, which will contribute to the development of cancer hyperthermia.

Change Behavior of Retained Austenite and Residual Stress on Carburized SCM420H Steel during Fatigue Process

M. Hayama, Y. Maki, S. Kikuchi, J. Komotori

鉄と鋼（Tetsu-To-Hagane/Journal of the Iron and Steel Institute of Japan) 108 （ 11 ） 891 - 899 2022

　View Summary

The transformation behavior of retained austenite in carburized SCM420H steel and its effect on the change in residual stress on a surface are investigated. The retained austenite on the carburized steel is transformed significantly in the first cycle of fatigue loading with a stress ratio of −1, and the transformation is less significant thereafter. Tensile loading significantly affects the transformation of retained austenite as compared with compressive loading. This is because the mechanical driving force that contributes to the martensitic transformation of retained austenite differs under tensile and compressive stresses. To investigate the transformation behavior of retained austenite and residual stress more comprehensively, an in situ X-ray measurement of retained austenite and residual stress is conducted. In the measurement, retained austenite or residual stress on a specimen surface is measured under loading conditions. Results show that the transformation of retained austenite under tensile loading involves a threshold stress value at which the transformation begins. The transformation of retained austenite proceeds when the applied stress exceeds the threshold value; however, no transformation occurs regardless of the number of loading cycles when the applied stress does not exceed the threshold. The compressive residual stress on the specimen surface increases as retained austenite transforms to martensite due to stress loading.
