Abstract
Results obtained from machining and conventional slow-speed compression tests are used to calculate the constants σ1 and n in the empirical stress/strain equation σ = σ1***enover a range of strain-rates (10-3to 2·8 times 104/s) and temperatures (room temperature to 200°C) for a low carbon, free machining steel. The results are consistent with those obtained for a similar material using high-speed tension tests. Some results showing the influence of higher temperatures (up to 800°C) on the flow stress are also obtained from the machining tests by considering the flow along the tool-chip interface. These results show a dynamic strain-ageing effect similar to that found in high-speed tension and compression tests on similar materials.Keywords
