Using four Japanese rimmed steels, the authors have done torsional test of round bars within the temperature range of -80°C to+200°C and compared these results with the notch toughness investigated by Charpy and notched slow bending test using U and V type standard Charpy syecimens.<BR>In order to discuss the judgment of the uotch toughness of materials from torsional testing results, we abopted the criterion, <BR>ψ=breaking twisting moment/breaking twisting angle (see Fig.8)<BR>Then we found the notable : (a) the valve of ψ remained constant within the experimental temperature range (-80°C-+100°C), being independent of testing temperature (see Fig. 7) and (b) material of which the value of ψ is lower shows the lower transition temperature (see Fig.9).<BR>Consequently, it could be said that the notch toughness of material may be specified by the value of room temparature as well as by the value of ψ and Φ at room temperature in tensile and notch slow behding test respectively.
