Effects of Precompression on the Surface Toughness of WC-5% Co

  • Silvana Bartolucci Luyckx

Abstract

During the 1960’s and early 1970’s several papers were published describing changes in the properties of WC-Co alloys resulting from prior compressive loading. The studies most relevant to the present work are those which describe the effects of: (a) plastic strains of up to 0.5% in WC-6% Co on resistivity, coercivity, bending strength and yield stress, by Ivensen and co-workers1; (b) plastic strains, in uniaxial compression, of up to 1% in WC-5.9% Co on hardness, coercivity and h.c.p./f.c.c. cobalt ratio, by Hara and Ikeda2; (c) plastic strains of more than 10% under non uniform triaxial compressive stress on resistivity, hardness, coercivity and compressive strength, by Pelepelin3; (d) uniaxial compression applied to WC-6% Co on the residual tensile stress in the cobalt, by Tumanov and co-workers4.
