| 抄録 | The influence of simulated welding cycles on the evolution of carbides in SQV-2A low alloy steel was studied. In the investigation TEM observations of thin foils and carbon extraction replicas were performed. Type and metal composition of carbide particles were determined by means of electron diffraction and EDX. In original and affected states Fe-rich M3C and Mo-rich M2C carbides were identified. The M2C carbide was found to incur only small changes during simulated welding cycles. There was confirmed a higher sensitivity of M3C carbide on short-term high-temperature welding processes. |
