Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)(ISAS)), Sagamihara, Kanagawa Japan, Thermophysical properties of high-temperature melts are indispensable for numerical simulations of materials processes. Accurate data are necessary to improve the process modeling, which leads to cost-effective production of high-quality products. However, crucial obstacles make measurements of thermophysical properties difficult at elevated temperatures because of high chemical reactivity and fluidity of melts. From the background mentioned above, the levitation technique, which provides containerless conditions during the measurements, is applied into the thermophysical property measurement. We are planning thermophysical properties of high-temperature melts using electromagnetic levitation technique under microgravity. Under microgravity conditions, convections in the levitated melts are suppressed, so we can accurately measure the transport properties, such as thermal conductivity. On the other hand, if we can suppress the convection on the ground conditions, we can evaluate the measurement data under microgravity conditions. Thus, we have been developed the system of thermophysical properties measurement by EML with a static magnetic field. The static magnetic field can suppress the convection in the levitated liquid metals droplets. Using the system, we have been measuring heat capacity, thermal conductivity, emissivity, surface tension and density of high-temperature metallic melts. Comparing the data obtained by the method to the data obtained under microgravity conditions, we can evaluate the accuracy of measurement data, and also we exactly know the effect of convection on the thermophysical properties measurements., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0065129025},
