Abstract
â¶ Very early stage RCF crack growth in rail steels is very microstructurally influenced. â¶ Initially cracks grow along favourably aligned, strained prior-austenite (PA) grain boundaries. â¶ RCF crack initiation favoured at PA boundaries with pro-eutectoid (PE) ferrite. â¶ Very short RCF crack growth is restricted/halted at PA boundaries when un-favourably aligned. â¶ 3D early RCF crack growth and deformed PA grain shapes are linked to ratcheting flakes.
