Conclusions 1. For steels of the transition (07Kh16N6) and martensitic classes (03Kh12N10MT) the fracture toughness is fairly high under plane strain conditions down to 4.2°K. 2. The fracture toughness of aluminum alloys 1201 and 01381 increases with decreasing temperatures down to 4.2°K, although the presence of defects in weld seams cuts the structural strength in half. 3. The fracture toughness of titanium alloy VT5-1kt is approximately the same as that of the steels at 4.2°K. The value of KIc decreases in liquid hydrogen, which is due to the interaction of the metal with gaseous hydrogen.
