“…It is applied to billets prepared by ingot or powder metallurgy techniques where the strain rate is closely controlled to prevent the oxidation of the TiAl based alloy sheets [3,4]. However, hot roll bonding is considered to be complex and costly [5,6] because it is performed isothermally followed by pack rolling to reduce the deformation resistance and improving stress states. (2) Explosive welding: Detonation wave and kinetic energy of the explosion product result in plastic deformation, local metal melting and even atomic mutual diffusion subsequently at the interface between the titanium and aluminum layers [7].…”

It's of great significance in high-temperature aeroengine applications for large-surface-area Ti-Al laminate composites to be fabricated into Ti-Al 3 Ti parts by plastic forming and subsequent vacuum hot pressing. Then the original layer thicknesses have an important influence on the interface bonding and mechanical properties of Ti-Al laminate composites, but only few reports about it have been published so far. In the present study, vacuum hot pressing was employed to fabricate Ti-Al laminate composites using Ti and Al foils of different thickness. The resulting interface bond and mechanical properties of Ti-Al laminate composites were then studied to determine the optimum sheet configuration and thickness. To further assess their formability and develop a forming limit diagram (FLD), 0.1/0.15 Ti-Al laminate composites were operated on

“…From the data of Table 3 , it is found that the average h associated with the F/SG interface is 42% larger than the average h associated with F/NSG (same ΔH), which indicates a stronger bonding strength between spiky graphite and ferrite, as compared with the interface between non-spiky graphite and ferrite. Given the morphology of the interface, it could be assumed that this bonding strength is of a mechanical nature [ 26 , 27 , 28 , 29 ]. Evidently, the emerging morphology itself, is a consequence of the diffusional mechanism of C dissolving from the cementite Fe 3 C (Fe 3 C → Fe + 3C) and migrating to the graphite interface [ 30 ], where intrusions and extrusions are possibly formed as a result of the Fe 3 C lamella intersecting with the graphite particles and, at such intersection points, the Fe 3 C dissolution will occur preferentially [ 31 ]; see Figure 8 .…”

Proposal of Characterization Procedure of Metal–Graphite Interface Strength in Compacted Graphite Iron

Compacted graphite iron is the material of choice for engine cylinder heads of heavy-duty trucks. Compacted graphite iron provides the best possible compromise between optimum mechanical properties, compared to flake graphite iron, and optimum thermal conductivity, compared to spheroidal graphite iron. The vermicular-shaped graphite particles, however, act as stress concentrators, and, as a result of delamination from the metal matrix, they are responsible for crack initiation during the thermomechanical fatigue cycles occurring through engine startup and shutdown cycles. Scratch tests driven over the matrix and into the graphite particles were performed in order to characterize the strength of the metal–graphite interface. Samples extracted from a cylinder head in as-cast condition were compared to samples subjected to a heat-treatment at 700 °C for 60 h. The former samples were composed of a primarily pearlitic matrix and graphite particles (~11.5 vol %), whereas, after annealing, a certain pearlite fraction decomposed into Fe and C, producing a microstructure with graphite–ferrite interfaces, exhibiting a partially spiky morphology. The scratch test revealed that the ferrite–graphite interfaces with spiky nature exhibited a stronger resistance to delamination compared to the ferrite–graphite interfaces with smooth morphology. One reason for the high interface strength is the mechanical interlocking between graphite spikes and ferrite, increasing the contact area between the two phases.

“…Palkowski et al [15] produced a sandwich composite of SS316L/polypropylene copolymer/SS316L by rolling joints through preparing the steel surface by corona discharge and used the two-component epoxy resin as a bonding agent between steel and polymer to fabricate the sandwich structure. Mousa et al [16] used the warm roll bonding and direct adhesion without the glue agent to build the sandwich composite of AL1100/ PU/AL1100.…”

In this study, a metal/polymer tri-layer composite was produced by direct adhesion (without adhesive), and mechanical locks were created using the warm rolling process. The effect of the process parameters including preheating temperature, rolling speed, thickness reduction, surface roughness, and the orientation of the surface scratches on the bond strength between layers was investigated. The results indicated that the suitable polymer fluidity and penetration, to provide stronger mechanical locks and higher bond strengths, could be achieved at an optimum preheating temperature and a rolling speed of 240°C and 36 r/min, respectively. In addition, the most appropriate surface pretreatment was obtained in the wire brush in the rolling direction mode with the surface roughness of 0.65 µm, so that the failure mechanism in this case was cohesive and the optimum thickness reduction was achieved at 40%. Furthermore, the mechanical properties of the sandwich sheet with highest bonding strength were evaluated.
