Abstract

Accurate material mechanical properties data at low temperatures are essential for design of economical, efficient, and safe structures for low temperature operation. Fracture toughness, tensile properties, and fatigue crack growth resistance characterize the mechanical performance of structural materials. Because construction of a sizable welded structure free from geometrical defects is a practical impossibility, adequate material toughness is needed to prevent crack growth and eventual fracture at such defects. Strength and stiffness enable a material to support its applied loads without stretching or buckling. Adequate fatigue crack growth resistance allows a part to continue to perform its function for a lifetime of load cycles. Compromises among toughness, strength, and fatigue resistance are required because no one material is best in all properties and because economy in material costs is necessary.
