“…The amplitude of the first and second feature is lower compared to the third metal-metal feature, due to the low weighting factor of boron [33]. The bond distances observed are in good agreement to literature [13,22,34]. Comparing the amplitude of the metal to non-metal bond population of the Co 43.5 Ta 6.1 B 50.4 and the Co 43.5 Fe 20 Ta 6.1 B 15.8 O 14.8 system it can be observed that the metal to non-metal population of the Co 43.5 Ta 6.1 B 50.4 system is higher.…”

Ab initio molecular dynamics simulations are used to systematically explore the influence of alloying on the stiffness and plasticity of Co–Fe–Ta–B metallic glasses. The Co(43.5)Ta(6.1)B(50.4) metallic glass studied in this work, with a Young’s modulus of 295 GPa, is the stiffest metallic glass known in literature. From the analysis of the density of the states it is suggested that the very large stiffness is due to strong covalent metal to boron bonding. Furthermore it has been observed that by alloying with Y, Zr, Nb, Mo, Hf, W, C, N and O the bulk to shear modulus ratio can be varied from 2.08 to 2.82. As noted by Lewandowski et al (2005 Phil. Mag. Lett.85 77) a brittle to plastic transition for metallic glasses can be identified in the range of 2.33 to 2.44. Hence, it is evident that the whole range from brittle to plastic behaviour can be covered,with the systems studied in this work. This evolution from brittle to plastic behaviour can be attributed to a change from predominately covalent to predominately metallic bond character.

“…There are reports in the literature on magnetic materials being prepared by cryomilling in the nanocrystalline form, such as NiCrAlY [252], NiCoCrAlYSi [163,253] MnBi [254], τ-MnAlC [255,256], MnAlC/α-Fe [257], Carbon doped MnAl [258], Cobalt ferrite [259],γ-Fe 4 N [260], BiFeO 3 [261]. The change in magnetic properties is mainly due to altering in crystallinity of the materials by cryomilling [262]. Similarly, Ni–Nb–Y was cryomilled for catalytic activity and showed higher activity for hydrogen evolution [263].…”

The milling of materials at cryogenic temperature has gained importance both in academic as well as the industrial community in the last two decades, primarily because of significant advantages this technique as compared to milling at room temperature; environmental friendly nature, cost-effectiveness, rapid grain refinement, less contamination, and large scale production capability of various nanomaterials. Scientifically, milling at cryo-temperature exhibits several distinct material related phenomena; suppression of recovery and recrystallization, predominant fractures over cold welding, significantly low oxidation, and contamination, leading to rapid grain refinement. Cryomilling has extensively been used to obtain finer scale powder of spices for the preservation of aroma, medicines for effective dissolution, or amorphization. It has been considered an environmentally friendly process as it utilizes benign liquid nitrogen or argon without discharging any toxic entity to the environment, making the process attractive and sustainable. The present review is intended to provide various scientific as well as technological aspects of cryomilling, environmental impact, and future direction.
