This is distinct from elastic deformation, which is reversible. In fact, copper alloys become stronger and more ductile as the temperature goes down, retaining excellent impact resistance to 20 K (-253 C or -424 F). I think "stiff is a better word to describe a "strong" but brittle material. Ultimate tensile strength (also called UTS, tensile strength, TS, ultimate strength or in notation) [1] is the maximum stress that a material can withstand while being stretched or pulled before breaking. A full bar means this is the highest value in the relevant set. Materials with high ductility and strength will have high toughness.
