“…Figure 2, depicts the FE-SEM pro les of all the BMG matrices after 30 h of milling, showing the presence of Ti and Nb nanoparticles ranging from 40 nm to 200 nm against an amorphous background, formed as a result of hot consolidation of powder mixture [29]. These images also show that the milling process converts the powdered metal particles from micro to nano and converts them into a dense BMG matrix.…”

We synthesized Bulk Metallic Glass (BMG) matrices using the general formula [Ni-(Mo/Cr)-Si]100−x:[Ti/Nb]x (x = 0–15 at.%) via mechanical high energy ball milling technique. Among them, one best sample is targeted in each series, based on their superior structural, thermal, mechanical and corrosion properties which are labeled as - NMST6 ((Ni75Mo15Si10)94Ti6), NMSNb10 ((Ni75Mo15Si10)90Nb10), NCST8 ((Ni75Cr15Si10)92Ti8) and NCSNb6 ([Ni-Cr-Si]94[Nb]6). The results revealed that mixing of optimum quantities of Ti/Nb content in the present BMG network helped to avoid embrittlement, overcome strain cracking problems, prevent pitting, and improved corrosive resistance which is essential to suit aerospace and lightweight vehicle applications. The variation in thermal (ΔT, Trg), mechanical (σy, εp, hardness) and potentiometric parameters (Ec, ic, Ep, ip) of all the targeted samples explained in the light of structural variation and glass modifying features due to the substitution of Ti/Nb in optimum quantities.

“…Compared to the rapid solidification techniques, the amorphous powders can be synthesized by MA in wider composition ranges (far from the eutectic temperature) and even from the elemental powders with positive heat of mixing [11]. Furthermore, the bulk glassy alloys with arbitrary shape and size can be fabricated by hot consolidation of the mechanically alloyed glassy powders in the temperature range of the supercooled liquid region, where the viscosity drops significantly [12,13]. Since MA is usually conducted at room temperature, it is expected that amorphous phase in the as-prepared powders should be in a more unrelaxed state with respect to that http of as-quenched alloys.…”
