In this paper, the surface residual stress of spheroidal graphite cast iron was measured by using critically refracted longitudinal (LCR) ultrasonic wave, X-ray diffraction (XRD) and blind-hole measurement methods. The test specimens used in this study were cut from a practical forging roller made from spheroidal graphite cast iron. The measurement results were compared and analyzed. They indicated that the measurement results obtained by this LCR method were consistent with those of the other two methods, which verified that for spheroidal graphite cast iron material, LCR method was an applicable, effective and reliable test technology of surface residual stress measurement.
