中文摘要The impact toughness of M951 alloy is investigated in temperature range between 20 degrees C and 800 degrees C. The results show that the impact toughness of samples impacted at 600 degrees C shows highest impact toughness value, the impact toughness value drops sharply when the samples impacted at 760 degrees C. In addition samples impacted at 800 degrees C show the higher impact toughness than that of samples impact at 760 degrees C. The scanning electron microscope observations show that cracks initiate at carbides particles due to high stress concentration, which leads to low impact toughness value at 20 degrees C. The dimples which can absorb more energy are formed during the impact at 600 degrees C. The samples impacted at 760 degrees C show lowest impact toughness. Additionally, the dimples nucleation, growth and coalescence are the major fracture mechanism at elevated temperature. (C) 2011 Elsevier Ltd. All rights reserved.
