Abstract We explored fabrication of ribbons of the FeCrNiAl alloy by rapid solidification method and succeeded in producing ribbons of 0.6 mm width and 30 μm thickness. The obtained ribbon-shape product is prospective for usage as blade material. The as-solidified product, however, is too hard and brittle for the succeeding punching operation to be applied for a final-product shape. This was found to be due to existence of extremely fine particles of NiAl based B2 phase uniformly dispersed in the matrix. We, therefore, searched for a heat-treatment for improving ductility and found an appropriate one. By this heat-treatment ductility was improved to such an extent that the punching operation was applicable. We then searched for a heat-treatment for producing Al2O3 on the surface which facilitates a hard and sharp blade-edge, and found an appropriate one. This heat-treatment simultaneously hardens the matrix once softened to an extent sufficient for supporting the Al2O3 layers. The final product is suitable for applications as blades, such as razors.
