摘要：
Behaviour of fracture toughness of molybdenum alloys is studied in a wide temperature range with consideration of fracture mechanisms on a microlevel. Molybdenum alloy CM-10 is chosen for this study. It manifests the most complete set of fracture mechanisms in the temperature range of brittle-ductile transition. The obtained temperature dependence of fracture toughness is analysed with regard for a sharpness of crack.
