Ultrasonic velocity method evaluating graphitization in low-carbon steel

LI Ping~(*1), LI Xi-meng~1, TAN Jia-long~1, WANG Lai~1, PENG Lian-jun~2( 1.Dept.of Mater. Eng., Dalian Univ. of Technol., Dalian 116024, China;2.PetroChina Com. Limited Dalian Petro-Chem. Com., Dalian 116023, China )  
The graphitization in low-carbon steel is one of the causes that lead to the worse material mechanical performance at high temperature. The ultrasonic velocity in 20~# steel graphitized specimens is measured in order to determine the possibility of ultrasonic evaluating graphitization in low-carbon steel. The results show that there is definite relationship between velocity and aging time. With the graphitization increasing, the velocity is decreasing according to the index law. The further analysis indicates that the main reason resulting in the decreasing velocity is that graphitization weakens the inter-atomic bonding force and cuts off the continuity of the body. Based on the relationship between inter-atomic bonding force and elasticity modulus, it will cause the reduction of elasticity modulus.
