Effects of testing conditions on the mechanical properties and fracture of a material in the course of impact loading have been studied. Using steels of various phase compositions (ferritic steel 08Kh18T1 and austenitic steel 10Kh18AG19) tested in a wide temperature range (from 20 to -196°C), the advantage of layered structures has been established as compared to monolithic. It has been shown that the testing of composite samples simulates the loading-affected behavior of the ferritic steel 08Kh18T1 with an inhomogeneous layered microstructure obtained during repeated hot rolling with a reduction of no less than 65%. © 2007 Pleiades Publishing, Ltd.
