    This paper focuses on the developed of spall-damage that occurs in pure iron as a result of repeated
    impact. The employed low-frequency scanning acoustic microscopy (LF-SAM) observations combined
    with the measurements of ultrasonic wave velocity, attenuation, backscattering intensity and amplitude
    spectrum of the reflected wave, enabled us to provide a nondestructive evaluation. The spall-damage distribution
    was analyzed in the C-scan images, and we found the spall-damage increase with impact stress
    when the latter exceeds the characteristic spall-threshold stress. Moreover, we recorded the decreased
    sound velocity, amplitude ratio, and the increase of backscattering intensity, significant attenuation
    (the high frequency component of the reflected wave) for enhanced impact stress. It was also demonstrated
    that the tiny cracks generated in iron develop significantly during subsequent impacts either with
    lower or higher impact stress. Since the presented results concern for the first time the multiple-impact
    experiments, we contend that the applied ultrasonic investigations constitute the effective method of
    nondestructive spall-damage evaluation.
