Abstract
A Fe61Cr2Nb3Si12B22 amorphous alloy rod sample of 8.8 mm diameter has been successfully prepared through explosive consolidation. The structure and thermal stability of the as-synthesized sample have been analyzed through X-ray diffraction (XRD) and differential scanning calorimeter (DSC) analysis. The results demonstrate that the sample still retains an amorphous structure, and the glass transition temperature (Tg), the crystallization onset temperature (Tx), the supercooled liquid zone (ΔTx) (Tx − Tg) and the reduced glass transition temperatures (Trg) (Tg/Tm) are 784 K, 812 K, 28 K, and 0.556, respectively. Its microstructure has been investigated by optical microscopy (OM) and scanning electron microscopy (SEM). The average microhardness of the alumina compact is about 1069 HV.
Highlights
Fe-based amorphous alloys, which are different from those of crystalline alloys for lack of long-range atomic order [1,2], have attracted increasing attention in recent years due to the high mechanical strength, strong corrosion resistance and good soft magnetic properties [3,4,5,6]

Summary
Fe-based amorphous alloys, which are different from those of crystalline alloys for lack of long-range atomic order [1,2], have attracted increasing attention in recent years due to the high mechanical strength, strong corrosion resistance and good soft magnetic properties [3,4,5,6]. Fe-based alloys have a lower amorphous-forming ability and require a very fast cooling rate during cooling [7,8]. Amorphous ribbons have been widely utilized in transformer cores or noise suppression sheets, it is difficult to obtain large-sized devices due to the preparation condition constraints of amorphous alloys [10,11]. For this reason, Fe-based amorphous alloys are significantly limited in practical applications. The preparation of a large-sized Fe-based bulk amorphous alloy has proven to be a quite significant research topic
