ABSTRACT In this study, microchannels with widths of 60, 100, 150, 200, and 250 µm were fabricated on the surface of Monel 400 alloy, and the effect of the rolling direction on the surface finish and etching depth was investigated. The obtained results revealed that the quality of the microchannel surface finish was better along the rolling direction than across the rolling direction, owing to the grain boundary orientations along the (001) plane. In addition, the etching depth increased along the rolling direction due to the presence of residual stress and plastic strain, which ultimately improved the microchannel quality.
