DYNAMIC PROPERTIES OF LOW-CARBON STEEL AFTER LONG-TERM STORAGE

摘要

Dynamic properties of low-carbon steel are investigated using the Kolsky method (the split Hopkinson pressure bar method). Changes in the properties of the steel after 50 years of storage are determined, and the destroyed samples are subjected to metallographic studies. The fractal dimension of the fracture contours is determined. It is shown that, the long-term storage of steel introduces no significant changes in its properties.
