| Abstract: | The thermal linear expansions and the related thermal expansion coefficients of some commercial steels,with carbon content from 0.09%-0.75%,at elevated temperatures were given through a thermal expansion test combined with thermo-physical calculation.At the temperature range of austenite phase,solid phase transformation and below the eutectoid reaction,the carbon content had different influence on the thermal linear expansions and their thermal linear expansion coefficient of steel.Based on the validation t... |
