Evaluation of the test temperature effect on failure mechanisms and notched impact strength characteristics of ultra-hard low alloy steels

  • Published:
Strength of Materials Aims and scope

We evaluate, by means of fractographic analysis of fracture surfaces, changes in failure mechanism depending on the test temperature of ultra-hard low alloy steels ARMOX 500 T and ARMOX 600 T. Experimental investigation temperatures range was from −80 to 100°C, where the occurrence of a limit state in material is highly probable.
