Abstract
⺠We studied lamellar spacing on fatigue crack growth resistance in TiAl-based alloy. ⺠Increase in cooling rate decreases distance between α2 plates, i.e., lamellar spacing. ⺠Air-cooled specimen with fine lamellae exhibited superior resistance to crack growth. ⺠This is due to zigzag crack growth across fine plates by linking microcracking. ⺠In furnace-cooled specimen crack growth resistance was improved by extrinsic effects.
