Published: 01 August 2018
DOI: 10.31399/asm.tb.msisep.t59220403
EISBN: 978-1-62708-259-4
... Abstract With cold work, mechanical strength (measured either by yield strength or ultimate tensile strength) increases and ductility (measured by elongation, reduction of area, or fracture toughness) normally decreases. This chapter discusses the mechanisms that produce these changes...
