“…MIL composites are primarily made by combining two different metals in a thin foil structure in a laminated structure and by exposing them to the required sintering processes. Such composites unite the ductility of the metallic phase and the hardness of the intermetallic phase without the brittleness of the intermetallics [3][4][5][6][7][8]. The electrical conductivity of composite materials is difficult to model and its modeling may need tensors [9][10][11][12][13].…”

Metallic-intermetallic laminate (MIL) composites possess intermediary properties emerging from the different laminates used. They are anisotropic since their properties are direction dependent. The laminates used in a MIL composite have different thermal conductivities and this results in anisotropic thermal resistance. In a recent study, using the composite dimensions and the electrical conductivity of the laminates used to make the MIL composite, the electrical resistance of rectangular prism-shaped MIL composites for different directions is examined. Since thermal and electrical circuits are analogues, a similar analysis can also be done for thermal conduction quantities. In this study, using the composite dimensions and the thermal conductivity of the laminates used to make the MIL composite, the thermal resistance of rectangular prism-shaped MIL composites for different directions is calculated and its direction-dependent parametric examination are made.

“…Compared to other welding methods, impact welding allows one to obtain high-efficiency joints between a wide variety of similar and/or dissimilar metals without forming intermetallic phases in the bond zones. In the literature, the microstructure and mechanical properties of tri-metal, Ti/Al and Mg/Al layered composites obtained by various methods are widely described [11][12][13][14][15][16]. Zhang et al revealed the interface microstructure of explosively welded Ti Gr.2/AA6061/AZ31B composite [17].…”

The Effect of Post-Weld Hot-Rolling on the Properties of Explosively Welded Mg/Al/Ti Multilayer Composite

et al. 2020

The paper describes an investigation of an explosively welded Mg/Al/Ti multilayer composite. Following the welding, the composite was subjected to hot-rolling in three different temperatures: 300 °C, 350 °C and 400 °C, with a total relative strain of 30%. The rolling speed was 0.2 m/s. The investigation of the composite properties involves microhardness analysis and mini-specimen tensile tests of the joints. The composite Mg/Al and Al/Ti bonds in the as-welded state and after rolling in 400 °C were subjected to microstructure analysis using scanning electron (SEM) and transmission electron microscopy (TEM). In the Al/Ti interface, the presence of melted zones with localized intermetallic precipitates has been reported in the as-welded state, and it has been stated that hot-rolling results in precipitation of intermetallic particles from the melted zone. The application of the hot-rolling process causes the formation of a continuous layer in the Mg/Al joint, consisting of two intermetallic phases, Mg2Al3 (β) and Mg17Al12 (γ).

“…[1][2][3][4] Some of the most interesting laminates in terms of the application for ballistic panels are Al-Ti alloy systems. [5][6][7][8][9] The appropriate technology for obtaining such laminated metal composites (LMC) is the explosive-welding method, a solid-state welding process, in which the metallic bond between the elements is formed due to a high velocity collision caused by the detonation of the explosive material. [10][11][12][13][14] As the result of a severe plastic deformation during bonding, as well as local mixing of the joined materials, melted zones (vortexes) can be formed.…”

Some of the most interesting materials with superior ballistic resistance are light-alloy laminated composite plates. The appropriate technology to produce these composites is the explosive-welding method. In this study, Ti6Al4V and AA1050 were successfully bonded during an explosive-welding process. The microstructure of the obtained bimetal joint was examined with scanning electron microscopy on the samples prepared using the ion-polishing method. Scanning electron microscopy allowed us to investigate the grain size in the joint area and the presence of the melted zones in the joint area, formed as a result of local mixing of both joined materials. In order to investigate the melted zones in terms of the presence of intermetallic compounds, linescans and transmission-electron-microscopy observations with SAED were performed. The obtained results allowed us to identify the intermetallic compounds, which occurred in the melted zones. The scanning-electron-microscope observations indicated a severe plastic deformation of both materials in the joint zone. An analysis of the microstructure of the joint zone with a particular emphasis on the melted zones was performed together with the tomography carried out with the focused-ion-beam scanning-electron-microscope method (FIB/SEM). The strain hardening of the joined materials was established with a microhardness analysis.
