Investigations of (martensite - austenite) M-A islands in HSLA X65 and X70 steels grade have been carried out. Since the traditional 'Nital' and 'Picral' etchants were inadequate for revealing M-A islands in a suitable way, a special technique of etching was prepared to obtain the effect of more selective etching for metallographic and scanning microscope studies. Metallograpgic investigations included revealing and evaluation of volume fraction of M-A islands as function of cooling time. TEM studies were performed to confirm the optical microscope observations.
