摘要：

In-situ observation and microstructure analysis were combined with the nanoindentation to study the effect of the orientation relationship between the s and g phases on the mechanical property of the 7Mo super austenite stainless steel. The results from the HRTEM and the nanoindentation indicate that the semi-coherent interface (111)g // (001)s (which is composed of several atomic layers in the absence of element segregation) pro-duced by eutectic transformation, effectively improves the strength of the interface.
