Tailoring magnetic characteristics of (Fe1−xCox)81Zr9B10 amorphous alloys via engineering crystallization processes

Effects of Heat Treatment on Microstructure and Magnetic Properties of Fe80Zr10B10 Alloy

“…During the crystallization, the resistance to steady-state crystalline phase precipitation from the amorphous phase is very large, and the alloy system will seek another transformation process with a relatively small transformation resistance. That is, a metastable crystalline phase is formed through non-equilibrium transformation, and the structure of the metastable crystalline phase is relatively close to that of the amorphous parent phase [22]. With the increase of annealing time, α-Mn precipitated to saturation, and then the α-Fe phase precipitated from the remaining amorphous phase.…”

“…Crystallization of Fe-based amorphous alloys has been an important research topic that has been extensively investigated over the past several decades. Different types of metastable crystallization phases are formed during primary crystallization, such as Fe 23 B 6 type [6][7][8][9][10][11], α-Mn type (χ) [12][13][14][15][16], cubic quasiperiodic (CQ) [17], Fe 12 Si 2 ZrB type [18,19], and β-Mn type phases [20][21][22]. FeZrB system alloys represent an important research direction for Febased alloys, and the crystallization phases of FeZrB alloys have been reported in several studies [23][24][25][26][27][28][29][30].…”

Effects of Cu and Co additions on the crystallization and magnetic properties of FeNbB alloy

“…Replacing Fe with Co in Fe-based soft magnetic alloys can affect the crystallization processes, [22] improve the high temperature soft magnetic properties [10] and saturation magnetization, [23] increase the Curie temperature, [24] and improve the plastic deformation ability of the Fe-based alloy. [25] Research on the effects of Co substitution of Fe on the structure and properties of such alloys is of considerable scientific interest.…”
