Popis: | The PrDyFeCoB microwires, whose diameter and cylindricity are controlled via rotation speed of a cooling cylinder and depend on time of droplet solidification on it, are obtained via extraction of a hanging melt droplet. The variations in cooling mode of a melt droplet lead to a change in cross-sectional shape from completely cylindrical to semicircle, crescent, and almost flat plate one. We found that the cooling mode affects not only the morphology, but also the mechanical properties, which are different for microwires of d-ifferent shapes, and changes the microhardness and Young’s modulus of different surfaces of the same microwire. |
