英文摘要	Tensile tests, high cycles fatigue tests and DSC analyses were carried out for K465 and K492 alloy. The morphology, distribution and type of primary carbide were investigated by SEM and TEM. Results show that MC-type carbide is formed as Chinese script morphology in K465 alloy. The tensile strength of as-cast K465 alloy is improved because of strengthening of Chinese script MC-type carbide. Primary MC-type carbide is also produced in as-cast K492 alloy. High-cycle fatigue strength of as-cast K492 alloy is decreased when carbide becomes blocky with the large size, while it is improved when carbide is dispersed and fine particles.
