초록

Recently, renewable energy sources such as wind turbine, solar cell are interested in preventing global warming which is caused by the consumption of fossil fuel. SCM440H and SNCM439 have been used in the major components of the wind turbine gear because of excellent mechanical properties. In the present study, the heat treated mechanical properties of SCM440H and SNCM439 with 150mm diameter were compared with those with 25 mm diameter which is generally accepted material for structural application. Heat treated SCM440H showed better mechanical properties such as tensile strength, hardness and impact absorbed energy compared with those in SNCM439. Hardenss value between as-quenched and as-quenched followed by tempering showed big difference in SNCM439, however the difference in SCM440H was relatively small. Heat treated mechanical properties of the alloys with 25mm diameter were more uniform value than those with 150mm diameter.
