“…In order to improve the macroscopic plasticity of BMGs, one of the most effective strategies is to prepare metallic glass matrix composites (MGMCs) by introducing a crystalline second phase as a reinforcement system to promote the shear band nucleation and suppress the shear band propagation [11][12][13]. The reinforcement of MGMCs is generally designed as a crystalline second phase, including in situ-precipitated crystalline phases and ex situ-added classical reinforcements such as carbon fibers [14][15][16][17], W fibers [18][19][20][21][22], ceramic particles [23][24][25], etc. As a common reinforcing particle in crystalline matrix composites, silicon carbide (SiC) particles are also used in MGMCs through different preparation methods and metallic glass (MG) matrices.…”

Ti-based bulk metallic glass (BMG) alloys have attracted widespread attention due to their strong glass forming ability, high specific strength, and good corrosion resistance. However, the poor plasticity of BMGs limits their further application in the aerospace and aircraft fields, as well as others. We optimized the composition of SiC-reinforced, Ti-based metallic glass matrix composites (MGMCs) through finite element modeling (FEM). FEM of MGMCs containing irregularly shaped SiC particles with different contents was conducted. Stress and strain analyses were conducted to evaluate the effect of the particle volume fraction on the mechanical behavior of MGMCs, and an optimization value of 30% was obtained, which is conducive to plasticity improvement. Arc melting copper mold injection casting was used to verify the optimized SiC content. The results show that the electroless nickel plating treatment effectively improves the wettability between SiC particles and the amorphous matrix, enabling the successful preparation of SiC/MGMC with a volume fraction of 29.5% through traditional injection casting. The volume fraction of SiC plays a crucial role in the transition of fracture mode from splitting to shear in MGMCs. After adding lightweight SiC particles, the yield strength, plasticity, modulus, and specific strength were improved by 25%, 1471%, 46%, and 33%, indicating that the use of nickel-plated SiC particles in MGMCs is an effective strengthening and toughening method for BMGs.

“…9). The adiabatic shear bands are localised damages that can occur under the high strain rate as a results of large shear deformation under adiabatic condition [47,48]. The adiabatic shear bands have approximately 45° inclination to the interface plane [47], and this phenomenon explains orientation of the fatigue cracks in Ti Gr.…”

Initiation and evolution of fatigue cracks at the interfaces in three-layer Zr–Ti/Zr–Steel composites is herein examined by in situ optical microscopy for the first time. Specimens cut out from three composite plates comprising Zr 700, Ti Gr. 1, and P265GH steel layers have been subjected to uniaxial fatigue cyclic loading. It is found that mechanical property mismatch between layers and defects at the interfaces can reduce the fatigue life of composite plates. An insight into the evolution of cracks initiated at the interfaces reveals that (1) most of the cracks grow into adjacent layers along two distinct planes, and (2) these cracks could lead to the fatigue failure of composites. One of these planes coincides with the adiabatic shear band orientation found in Ti Gr. 1 and Zr 700 layers. The interfaces in multilayer metallic composite could have excellent fatigue strength depending on their structural properties.

Destruction by munitions mainly relies on their warheads, and research on improving the destructive effectiveness of warheads has focused on new explosives, improving the warhead structures, and adopting new types of destructive elements. The limitations of the single kinetic damage mechanism and damage mode of the inert damage element largely restrict the enhancement of destructive effectiveness of conventional warheads. Therefore, a new type of reactive material has been developed, namely, reactive alloys, which include metal composite materials, amorphous alloys, and high-entropy alloys. The common characteristic of these alloys is that they contain reactive metal elements (Al, Mg, Ti, Zr, etc.), which easily undergo oxidation under high-temperature conditions. Compared with the traditional metal-polymer and other reactive composites, these alloys have higher density and strength, excellent mechanical properties, and broader application prospects. The exothermic reaction properties of reactive alloys under high-velocity impact conditions facilitate strong ignition and detonation effects and considerably improve their destructive effectiveness. Current researchers have mainly investigated the impact-induced reaction mechanisms of reactive alloys by conducting various impact tests. They found that the mechanism involves several stages: From material crushing to materials undergoing reaction, i.e., the material is first crushed by the impact compression and dispersed into many fine particles, and the temperature of the material increases rapidly in the meantime, and finally, an intense oxidation reaction occurs in the material after being heated. This paper focuses on three aspects that need to be addressed during the impact-induced reaction mechanisms of reactive alloys: (1) The fragmentation mechanism and size distribution trend of the generated fragments after a material impacts the target, (2) the relation between the transient temperature and fragment size due to the impact and adiabatic shear, and (3) reaction temperatures and size thresholds for the fragments to undergo the chemical reactions. Recent research progress on these three problems was summarized to reveal the reaction mechanism of reactive alloys. Because reactive alloys have excellent mechanical properties, they can be used in various future armor-piercing munitions, shaped charges, and fragmentation materials. They can also be directly made into reactive material shells. Conducting subsequent work will be conducive to promoting the application of reactive alloys. In the future, reactive alloys can be applied to fabricate more destructive elements to realize the integration of structure and function, which will substantially improve the reliability of the warheads, simplify the design space, realize high efficiency of the munition's destructive effectiveness, and remarkably improve the integration of structure and function of warheads.
