Influence of Solidification Speed on Quality and Quantity of Structural Defects in Fe_(61)O_(10)Zr_(2.5)Hf_(2.5)Y_2W_2B_(20) Amorphous Alloy

摘要

The microstructure of Fe_(61)Co_(10)Zr_(2.5)Hf_(2.5)Nb_2W_2B_(20) amorphous alloy in the form of ribbons obtained by classical melt spinning and plates obtained by an induction suction method were investigated using X-ray diffraction. The type of structural defects were studied by analysis of the magnetization characteristics near ferromagnetic saturation of the sample. It was shown that the presence of structural defects is strongly correlated with sample thickness and production process. It was shown that ribbons with cooling rate between 10~5-10~6 K/s have point type defects, wires obtained with lower cooling rate between 10~1-10~2 K/s, have linear type defect (quasi-dislocation dipoles). crystallization.
