The tensile fracture of spheroidised plain carbon steels is predominantly initiated by cracking associated with the carbide particles as reported by Liu and Gurland. The increase in the number of voids resulting from such cracking as a function of tensile strain at room pressure has been investigated by Gurland who found that cracking of the carbide particles began in the early stages of plastic deformation. In the present work the development of voids originating from cracks associated with carbide particles has been investigated as a function of strain at a number of superimposed hydrostatic pressures.
