Abstract: An Fe-based amorphous alloy ribbon reduced in iron loss, less deformed, and highly productive in a condition of a magnetic flux density of 1.45 T is provided. One aspect of the present disclosure provides an Fe-based amorphous alloy ribbon having first and second surfaces, and is provided with continuous linear laser irradiation marks on at least the first surface. Each linear laser irradiation mark is formed along a direction orthogonal to a casting direction of the Fe-based amorphous alloy ribbon, and has unevenness on its surface. When the unevenness is evaluated in the casting direction, a height difference HL×width WA calculated from the height difference HL between a highest point and a lowest point in a thickness direction of the Fe-based amorphous alloy ribbon and the width WA which is a length of the linear irradiation mark on the first surface is 6.0 to 180 μm2.

Abstract: A prediction apparatus uses microstructure images acquired from a material as learning data to build a generative model for generating a microstructure image of the material, and, by learning data of process conditions paired with the microstructure images of the material, builds a process condition prediction model. The process condition prediction model is a regression model and is for predicting process conditions for any microstructure images. The prediction apparatus generates a microstructure image of a material by inputting sampled latent variables into the generative model, and enters the generated microstructure image of the material into the process condition prediction model so as to generate a microstructure image of a material and, at the same time, predict process conditions for the microstructure image.
