摘要：

There were many attempts to correlate Charpy absorbed energy with fracture parameters. Most of these gave empirical or semi-theoretical equations showing this correlation. In the present paper the dynamic yield strength is used to obtain the relation between Charpy V and K-IC. Comparison is made between three structural steels (1.0570 - 1.0511 - 1.8900) and the alloy Ti-Al6-V4. For the steels, fracture toughness experimental values are coherent with those based on data determined with the derived relation. For Ti-Al6-V4 the values deviate from each other, particularly at room temperature, when the contribution of alpha-phase is more important.
