— Observations of fatigue crack growth in smooth specimens under biaxial loading are reviewed, with particular reference to the Stage I to Stage II and Stage II to Stage I transitions. Further results are presented for 1% Cr‐Mo‐V steel and AISI 316 stainless steel at various temperatures, showing that all cracks may be classed as either Stage I or Stage II. Predictive criteria are suggested for the typè of crack obtained, and the mechanisms for elevated temperature crack initiation are discussed.
