Mechanical properties for bulk metallic glass with crystallites precipitation and second ductile phase addition

Strain localization in metallic amorphous/amorphous composites

“…It shows in addition a definite dependence on the mechanical properties of the individual MG phases forming the composite. In a sense, observations remind to the case of MG composite obtained by fine mixing of amorphous phases and micrometer-and nanometer-sized ductile particles [2,9,[42][43][44][45][46][47][48][49][50][51]. The inhomogeneous microstructure produced by inclusions in the MG matrix permits to avoid the dramatic failure of the glass and its fracture by limiting the possible extension of SBs [2,9,[42][43][44][45][46][47][48][49][50][51].…”

“…The inhomogeneous microstructure produced by inclusions in the MG matrix permits to avoid the dramatic failure of the glass and its fracture by limiting the possible extension of SBs [2,9,[42][43][44][45][46][47][48][49][50][51]. These are either deflected or suppressed as a consequence of the interaction with the inclusion of different mechanical properties and an enhanced plasticity results [2,9,[42][43][44][45][46][47][48][49][50][51]. The idea underlying the described approach is that an inhomogeneous microstructure favors the multiplication of SBs because of the higher energy necessary to move a given SB across the inclusion [42][43][44][45][46][47][48][49][50][51].…”

Fabrication and mechanical properties of a tungsten wire reinforced Cu–Zr–Al bulk metallic glass composite

“…a cleavage-like fracture and step-like pattern with about 2 m size (Fig. 7e), suggesting that the propagation of shear bands or microcracks effectively hindered during the compression process [19,25,26].…”

Synthesis and Indentation Behavior of Amorphous and Nanocrystalline Phases in Rapidly Quenched Cu–Ga–Mg–Ti and Cu–Al–Mg–Ti Alloys

“…For the composition determination, a quantitative EDX was performed. Figure 3 It is noteworthy to mention that the formation of nanocrystalline or amorphous state in the rapidly solidified CuAl-Mg-Ti alloy may enhance the ductility and toughness [6,[17][18][19][20][21]; hence, it has a possibility for use as a coating material. Keeping in view the fact that the size distribution and volume fraction of fine scale nanophases can significantly alter the physical and mechanical properties of brittle intermetallics [22], studies on indentation characteristics of these alloys were taken.…”
