Add to ORKG金沢大学大学院自然科学研究科In order to study the influence of stress ratio and WC grain size, the characteristics of fatigue crack growth were investigated in WC-22wt.%Co cemented carbides with two different grain sizes of 3 and 6μm. Fatigue crack growth tests were carried out over a wide range of fatigue crack growth rate covering the threshold stress intensity factor range ΔK_. The fatigue tests were conducted at 10Hz and two stress ratios R=0.1 and 0.5 in laboratory air at room temperature using the 3-point bending specimens. It was found that the crack growth rate da/dN against the stress intensity factor range ΔK depended on stress ratio R. The crack growth rate plotted in terms of the effective stress intensity factor range ΔK_ (after allowing for...
