[K1.4] [Invited Lecture] Growth behavior of intergranular carbides in martensitic heat-resistant steel

*MITSUHARA Masatoshi¹, Yamasaki Shigeto¹, Arakane Ryoga¹, Nakashima Hideharu¹, Nomura Kyohei², Kubushiro Keiji² (1. Kyushu University, 2. IHI Corporation)

Keywords:Heat resistant steel、Creep、M23C6 carbides

Carbides on grain boundaries contribute the microstructural stabilization during creep in heat-resistant steels. Effects of boundary character and stress on the growth of carbides will be discussed.
