Abstract A study of the occurrence of temper-brittleness in bainitic structure has been made. It wasfound that the tendency of temper-embrittlement in the lower bainite was slightly less than thatin the tempered martensite whik the temper-embrittlement in the upper bainite was slightly greaterthan that in pearlitic structure, and the tendency of temper embrittlement of the temperedmartensite was much greater than that of the pearlite. The temperature range of temper-brittleness was 460—580℃ for upper bainite, 430—620℃ for tempered martensite, and the tem-perature of maximum temper-embrittlement appeared to be about 530℃ for both. It was sug-gested that the mechanism of temper-brittleness is the same for both structures.
