“…During liquid -solid transformation, second ductile phase can be made to form in ex-situ or in-situ (Fig - 4) fashion which is the introduction of ductile second phase particles in the glassy matrix by external physical addition and mixing (former) [218,221,[280][281][282][283][284][285][286][287][288][289][290] or internal nucleation and growth during solidification (later) [12,18,21,32,203,[291][292][293][294][295][296][297][298][299][300][301][302][303] while during solid -solid transformation this second ductile phases form as a result of heating of glassy solid which can relax or crystallise second phase particles out of full glass structure [37,41,44,257,260,262,264,265,[304][305][306][307]. From process perspective, their production methods ranges from convention...…”

Bulk metallic glasses (BMGs) and their composites (BMGMC) have emerged as competitive materials for structural engineering applications exhibiting superior tensile strength, hardness along with very high elastic strain limit. However, they suffer from a lack of ductility and subsequent low toughness due to the inherent brittleness of the glassy structure which render them to failure without appreciable yielding owing to mechanisms of rapid movement of shear bands all throughout the volume of the material. This severely limits their use in fabricating structural and machinery parts. Various mechanisms have been proposed to counter this effect. Introduction of secondary ductile phase in the form of in-situ nucleating and growing dendrites from melt during solidification have proved out to be best solution of this problem. Nucleation and growth of these ductile phases have been extensively studied over the last 16 years since their introduction for the first time in Zr-based BMGMC by Prof. Johnson at Caltech. Data about almost all types of phases appearing in different systems have been successfully reported. However, there is very little information available about the precise mechanism underlying their nucleation and growth during solidification in a copper mould during conventional vacuum casting and melt pool of additively manufactured parts. Various routes have been proposed to study this including experiments in microgravity, levitation in synchrotron light and modelling and simulation. In this report consisting of two parts which is a preamble of author’s PhD Project, a concise review about evolution of microstructure in BMGMC during additive manufacturing have been presented with the aim to address fundamental problem of lack in ductility along with prediction of grain size and phase evolution with the help of advanced modelling and simulation techniques. It has been systematically proposed that 2 and 3 dimensional cellular automaton method combined with finite element (CAFE) tools programmed on MATLAB® and simulated on Ansys® would best be able to describe this phenomenon in most efficient way. Present part consists of general introduction of bulk metallic glass matrix composites (BMGMC), problem of lack of ductility in them, measures to counter it, success stories and their additive manufacturing.

“…Up to now, there are W f / Zr-based [56][57][58][59][60][61][62], W f / Cu-based [63], Cu f / Zr-based [64], Ta f / Zr-based [65], stainless-steel fiber / Zr-based MGMCs (the subscript, f, denoting fibers) [66]. For this kind of composites, the modulus of the composites is usually calculated, using the Rule of Mixture (RoM): where E c , E f , and E m are the moduli for the composite, the fiber, and glass matrix, respectively, and f is the volume fraction of fibers.…”

The mechanical properties of ex-situ and in-situ metallic glass matrix composites (MGMCs) have proven to be both scientifically unique and of potentially important for practical applications. However, the underlying deformation mechanisms remain to be studied. In this article, we review the development, fabrication, microstructures, and properties of MGMCs, including the room-temperature, cryogenic-temperature, and high-temperature mechanical properties upon quasi-static and dynamic loadings. In parallel, the deformation mechanisms are experimentally and theoretically explored. Moreover, the fatigue, corrosion, and wear behaviors of MGMCs are discussed. Finally, the potential applications and important unresolved issues are identified and discussed.

“…With the increase of the ratio of height to width, the deviation extent of the shear surfaces from the theoretical positions increases gradually. In general, BMG specimens exhibit a brittle fracture and the fracture occurs along about 45°with respect to the loading axis [17,18]. The prerequisite of appearance of the particular mechanical behavior is the premature rupture of the BMG specimens during loading, resulting in almost no changes in the macro-sizes of the BMG specimens and very small deviations in the direction angles of shear surfaces.…”
