Abstract :
The purpose of this study is to investigate the thermal embrittlement and the mechanical properties of 2.25Cr–1Mo steel aged at high temperature for extended periods. Original and aged materials were tested to obtam the tensile strength, hardness and impact-absorbed energy. The tensile strength, hardness and impact-absorbed energy decreased as aging time was increased. X-ray dirtraction was used to study changes in carbide structure. These changes lead to thermal embrittlement.
