摘要：
The effect of volume fraction V;and carboncontent（%C）;of martensite was studied on the fa-tigue crack propagation behaviour of plain carbonmartensite plus ferrite M+F dual-phase steel.Theexperimental results show that the △K;decreasesand da/dn increases with increasing V;and（%C）;at a load ratio R=0.05.High△K;valuesare obtained by obvious crack closing ability causedby high roughness of the fractured surfaces.
