“…The work investigates the contribution of each parameter mentioned, called bilayer parameters. Bending strength in TiB/Ti material [42] is correlated with our parameter, considered as TiB/Ti layer flexural strength. Moreover, for the wide range of both layers' strength value, the maximum value of flexural strength is 1989.35 MPa [43].…”

A mathematical model was developed to determine the order of failure of layers in a two-layer ceramics composite and to determine the conditions for achieving the maximum limit load under three-point loading. The model was set in the space of three “bilayer parameters”: the ratio of the thickness of the lower layer to the whole thickness of the beam, the ratio of Young’s moduli of the lower layer to the upper layer, and the ratio of flexural strengths of the materials of the lower layer to the upper layer. The adequacy of the model obtained was confirmed by experimental results on the three-point bending of the experimental specimens. The experimental samples were two-layer composites consisting of a cermet layer TiB/Ti and a layer of α-Ti. The samples were obtained by free self-propagating high-temperature synthesis (SHS) compression and with varying their thickness. The results obtained make it possible to predict in advance which layer, based on the specific bilayer parameters, will trigger the brittle fracture mechanism as well as to set the maximum destructive load of bilayer composites.

“…Nano-tribology, which is represented by atomic simulations based on molecular dynamics (MD) technology, has advanced greatly over the past few decades as a result of improvements in computational techniques and computer hardware. MD is a perfect technique for atomic-scale experimentation because it reveals surface interactions, which can lower experiment costs and speed up experimentation [3] . The Newton (or Langevin) motion equations that describe their interactions are solved using the classical MD, which is effectively the kinesiology of computing atoms (or representative "particles") [4] .…”

At the nanoscale, it is still unclear what the mechanical characteristics of a TiAl alloy with vacancy defects are during friction with diamond tips. In this study, a molecular dynamics simulation-based sliding friction mechanism model between a diamond tip and TiAl alloy was created. The wear mechanism at the nano scale was explored in conjunction with friction force, removal atoms, and subsurface damage, and the sliding friction behavior of a TiAl alloy with varying densities of vacancy defects. According to its study, the initial peak of friction strength and the shaking breadth of the aluminum alloy material are reduced when vacancy defects rise. Additionally, it was discovered that when there is a vacancy defect, wear and sliding position adjustments are also in line with Archard's law of wear, and subsurface damage is transmitted from the concentration at the contact point to the front end of the touch point.

“…Various materials were manufactured by SPS including pure metals [10,25], metallic alloys [26][27][28][29], ceramics [30,31], ex situ composite [32,33], in situ composite [34,35], etc. Moreover, SPS is used for the production of highly porous materials or foams [36,37], production of functional gradient materials [38,39], joining and welding of dissimilar materials, and refractory compounds [40,41], and sintering of multi-layer materials in the form of laminates [42,43]. For further reading, refer to a comprehensive review of SPSproduced materials provided by Orru `et al [44].…”

Copper and its alloys have been in the service of humankind earlier than any other metal throughout history. In the present review, all aspects of the SPS of copper and its alloys are comprehensively investigated, and their potential effects on the microstructure and properties of alloys are thoroughly reviewed. In this regard, the densification phenomenon during SPS treatment is fully investigated. The effects of raw powder characteristics involving particle size, contamination content, and powder morphology on the sinterability of these materials are examined. Then, the influence of SPS operation parameters consisting of pressure, heating rate, dwelling time, pulsed electrical current, electrical pulses pattern, sintering temperature, and sintering tooling on densification of these materials is extensively discussed. Furthermore, the microstructure evolution and grain growth behaviors during SPS are explored. In addition, current challenges and future perspectives of this field are addressed.
