Description
Summary:Abstract This article presents a comparative analysis of the mechanical properties of steel 20 (ASTM 1020) and steel 09G2S (ASTM A516 Gr 70) used in the construction of amphibious all-terrain machines developed for operation in the Arctic and Antarctic. Research included static tensile tests, hardness measurements, fracture toughness measurements, and fractographic studies. Experimental investigations were carried out in the temperature range from –60°C to +50°C. As a result of the studies, the express-method for assessing the material state according to hardness measurements is proposed.
