摘要：
An austenitic nitrogen alloyed steels with high nickel contents has been investigated. Specimens have been shockloaded with pressure peaks from 100 to 600 kbar. It can be shown that the rise in hardness increases mostly from 500 to 600 kbar. From the shockloaded plates tensile and compression specimens have been drawn. For strongly shocked specimens quasistatic tensile tests show no uniform elongation but a very high tensile stress. Dynamic compression tests have been performed also. The fracture of specimens was characterized by scanning electron microscopy. Metallographic investigations have been also performed.
