The SZ exhibits strong contrast in the advancing side and relatively weak contrast in the retreating side.
'RS' and 'AS' of the notations means the retreating and the advancing sides, respectively.
Cr-rich borides containing Fe and Mo were detected in the advancing side of the SZ.
They also thank Daido Steel Co., Ltd., for providing the HNSS in the ISIJ Forum on high nitrogen steels.

Introduction Partial differential equations are among the most widely used to describe systems engineering.
Unfortunately, an implicit method in two space dimensions requires a set of equations to be solved at the advanced time level, which is not always easy to accomplish directly [2].
