Cyclic fracture behaviour of 20MnMoNi55 steel at room and 20mnmoni55

Jul 01, 2015 · Cyclic fracture behaviour of 20MnMoNi55 steel has been evaluated at room temperature and elevated temperature of 300 °C. Fracture resistance at elevated temperature was found to be lower than that at room temperature. The deterioration in fracture resistance was due to dynamic strain ageing. Cyclic loading amplitude and frequency were also found to have an influence on fracture resistance 20mnmoni55DIN-20MnMoNi55-SEW - < h2>Translate this page
