Low-Temperature Short-Time Annealing Induced High Strength and Ductility in a Cryorolled Pure Nickel

Journal Article


Abstract


  • Both the yield strength and ductility of cryorolled nickel were improved after short-time annealing at low temperatures. The yield strength, tensile strength, uniform elongation, and elongation to failure of annealed pure nickel reached 990 MPa, 1041 MPa, 6.4, and 8.7 pct, an increase of 18, 12, 700, and 521 pct, respectively, compared to unannealed state. The improvement in mechanical properties was attributed to the heterostructure formed by annealing, formation of stacking faults, and nano-twins.
