内容記述 | The fatigue crack growth tests of WC-Co Cemented Carbides were carried out in a wide range of fatigue crack growth rate covering the threshold stress intensity factor range ΔK_<th>. The effects of the stress ratio, Co volume faction and the phase transformation of Co on the fatigue crack growth characteristics were investigated on the basis of fracture mechanics and fractography. The crack growth rate was measured using 3-point bending specimens. Crack growth tests were carried out at 10Hz and the stress ratio R=0.1 and 0.5. The main results obtained are as follows;(1)The Paris rule can be applied between da/dN and ΔK and it is shown to be da/dN=C(ΔK)^m.(2)The fractography of the fracture surface, shows that brittle fracture occurs in the Co binder phase at the stress rate R=0.1 but ductile fracture occurs in the Co binder phase at R=0.5. (3)The relation of da/dN-ΔK_<eff>/E of WC-Co cemented carbides shows the characteristic in the middle of the other metals and the alumina ceramics. (4)The Co binder phase undergoes phase transformation by repeated deformation and so it affects the characteristics delicately. | |||||
