- Abstract
- Compression testing was carried out on 0.1%C - 0.9%Mn steel at various temperatures and strain rates. Peak strain behaviour was investigated as function of temperature and strain rate. Normalisation of flow stress in the stress strain curves by peak stress exhibits an interesting trend that the normalised value changes as strain, strain rate and temperature vary. Three regions could be characterised based on the way that the softening factor defined as the difference in normalised value between the peak stress and the flow stress at a strain of 0.5 changes with temperature. It was shown that tensile elongation behaviour could be predicted based on the softening factor determined in compression tests, As the softening factor increases, tensile ductility increases.
