Static and dynamic loading tests were used for studying the hardening of austenitic steels. The stable and unstable austenitic systems differ greatly in their ability to undergo deformation, and the hardening process takes place according to different mechanisms. Static deformation of Mn steels resulting from pressure by Brinell hardness testing balls is characterized by a greater increase of the hardness under the indentation and a more uneven distribution of this hardness than similar testing of Ni steels. The action of the introduction of C in increasing the resistance against plastic deformation is also stronger in the case of Mn steels. In these steels below 200 f C the non- ferromagnetic EPSILON -martensite is formed together with the alpha - modification. Dynamic loading produces a stronger hardening effect than static loading. Repeated sudden loading action of Mn steels results in a greater retardation of the hardening process than in Ni steels and saturation is reached at an earlier stage. Cavitation testing causes an increase of the fracture resistance of the metal by orders of magnitude. (TTT)
