Abstract

The paper evaluates, with the help of a fracture surface fractographic analysis, changes in failure mechanism depending on the test temperature of ultra-hard low alloy steels ARMOX 500T and ARMOX 600T, which are used for the means of containerization. The evaluation is based on experimentally determined values of absorbed energy measured by means of an impact test. Experimental investigation temperatures ranged from –80 °C to +100 °C, where the occurrence of a limit state in material is highly probable.
