— In this study, the relation between fracture toughness and mechanical properties, grain structure, temperature and strain rate is analysed on the basis of a thermo‐activation analysis of the plastic deformation of metals. As a result of the study, the relationships obtained are of sufficient accuracy in relation to standard cracked samples of many steels. These relations can be used as a tool when designing new alloys which have a strong resistance to crack growth. This study is limited to temperatures in the range 0 ≤ T ≤ 0.2T m and BCC metals.
