“…The interpenetrating network composed of Cu 2 GeSe 3 and Sb 2 Se 3 is very close to the typical lamellar structure formed by eutectoid crystallization. A similar phenomenon has been reported by Zhou et al in a study of the crystallization of FINEMET alloys . While the crystallization in most samples is diffusion‐controlled and results in crystallization peaks with long tails, the crystallization in the alloy Fe 74.5 Si 13.5 B 9 Nb 3 shows the features of direct impingement, which is ascribed to the eutectoid crystallization in this samples .…”

The photoelectrical glass-ceramics GeSe 2 -Sb 2 Se 3 -CuI which contain self-organized heterojunction networks is a novel and promising photovoltaic material. Here, a series of these glassceramics with gradually changed GeSe 2 /Sb 2 Se 3 ratios are studied. The composition dependence of the crystallization behavior is analyzed by differential scanning calorimetry and compared with the composition dependence of the photoelectrical properties. It is revealed that the glass-ceramics with evident photoelectrical response show two common features in differential scanning calorimetry curves: an overlapping crystallization peak attributed to the coprecipitation of Cu 2 GeSe 3 and Sb 2 Se 3 , and peak profiles showing the characteristics of direct impingement growth. Based on these results, it is concluded that the formation of the heterojunction networks in the photoelectrical glass-ceramics is ascribed to the kinetically allowed eutectoid crystallization of Cu 2 GeSe 3 and Sb 2 Se 3 .

“…Hence, in order to obtain a fundamental understanding of the individual effects of Cu and Nb alloying additions in Finemet alloy particular attention should be paid to the influence of separate additions of Cu and Nb to the reference Fe-Si-B alloy. For the Fe 74.5 Si 13.5 B 9 Nb 3 alloy earlier work has been carried out to study the thermal properties and phase formation [8][9][10][11][12][13][14]. However, due to the complex phases formed after crystallization in the Fe-Si-B-Nb alloy detailed microstructural observations and corresponding SADP analysis by TEM have not been reported so far.…”

“…1,2) In recent years, [3][4][5][6][7][8][9][10][11][12][13] many researchers committed to improve the soft magnetic properties by adding elements (Nb, Zr and Cu) to Fe-based alloys. Great progress 6,7,[11][12][13] had been made by simultaneously adding P and small amounts of Cu into Fe-based alloys.…”

The effect of simultaneously adding P and Cu on the crystallization behavior of hetero-amorphous FeSiB alloy was investigated. Thermal properties and microstructure evolution were studied by means of X-ray diffraction, transmission electron microscopy, differential scanning, and isothermal calorimetric methods. It is found that the addition of P and Cu to the FeSiB alloy changes its crystallization temperature as well as the apparent activation energy for crystallization. The crystallization process is mainly dominated by three-dimensional growth with various nucleation rates for the selected FeSiB(PCu) alloys. The phases formed during crystallization for the different alloys of Fe 84 Si 4 B 12 , Fe 83:3 Si 4 B 12 Cu 0:7 , and Fe 83:3 Si 4 B 8 P 4 Cu 0:7 are similar. The refinement effect of adding P and Cu to the FeSiB alloys is observed. The mean size of -Fe phases decreases from 200 nm to about 20 nm.
