Abstract

The influence of the structural factor (grain size) on the mechanical characteristics of austenitic steel (Fe–18Cr–10Ni–1Ti) in a vacuum and a liquid lead medium was studied. It was shown that increase in grain size of austenitic steel shows a slight decrease in the tensile strength of material in both vacuum and liquid lead. Plasticity (elongation) also decreases both with increasing grain size and with increasing temperature.
