    This work reports the mechanical properties of irradiated molybdenum (Mo) and its alloy, TZM. Recrystallized and stress-relieved specimens were irradiated at five temperatures between 373 and 800℃ in FFTF/MOTA to fluence levels of 6.8 to 34 dpa. Irradiation embrittlement and hardening were evaluated by three-point bend test and Vickers hardness test, respectively. Stress-relieved materials showed the enough ductility even after high fluence irradiation. The role of layered structure of stress-relieved specimen was discussed

    溶鉱炉の増風にともなって現われる諸現象を追求するとともに,過度の増風によって操業不能が起こる場合,これを規定する要因を解明した.最大出銑量に対応する送風量を種々の方法によって推定し,試験溶鉱炉については,最大出銑量を規定する熱的要因および物理的要因が,ほとんど同時に現われることを確かめた.いずれについてもシャフト部における装入物の運動状態が,これらの要因を規定する最大の因子であった
