Abstract:

In this study, through an analysis of vibration response characteristics of joint surface stiffness on dangerous rock mass, the relationship formula between amplitude ratio of the dangerous rock mass to the bedrock and the length of the bonding section of the joint surface is determined. The stability of the rock mass can be evaluated by combining the formula with the existing rock-mass limit equilibrium theory. This study proposes the existence of a resonance bonding length for the dangerous rock mass. When the length of the bonding section reaches the resonance bonding length, the dangerous

Abstract:

Ultra-pure copper sputtering target is a key material widely used in large-scale integrated circuits with 90-28 nm feature size. The copper target for 300 mm integrated circuit requires a reliable diffusion bonding between the ultra-pure copper target and the copper alloy backplate. The bonding ratio and bonding strength of diffusion bonding should reach over 99% and 80 MPa respectively. In this paper, the ascendant structure of electron beam welding united diffusion bonding with high quality was designed. The ultra-pure copper target and the C18000 copper alloy backplate were machined to coor

Due to the acceptable high-temperature deformation resistance of Inconel 718, its welding parameters such as bonding temperature and pressure are inevitably higher than those of general metals. As a result of the existing punitive processing environment, it is essential to control the deformation of parts while ensuring the bonding performance. In this research, diffusion bonding experiments based on the Taguchi method (TM) are conducted, and the uniaxial tensile strength and deformation ratio of the experimental joints are measured.

Abstract The interfacial structures of TiAlN/VN and TiAlN/NbN multilayers with different modulation ratios were studied using first-principles calculations. The results show that the interfacial bonding strength of TiAlN/VN remains relatively constant across different modulation ratios. In contrast, the interfacial bonding strength of TiAlN/NbN varies significantly with the modulation ratio. When the tTiAlN:tNbN ratio is 1:4, the simulated tensile and shear strengths of the TiAlN/NbN interface reach their highest values, 10.08 GPa and 5.13 GPa, respectively. This sensitivity arises from the mo

Abstract:

To study the effect of the bonding area on the dynamic failure process of a reinforced concrete beam with the same reinforcement ratio, the experimental and numerical researches on the impact response of notched reinforced concrete beams in the low-velocity regime (≤2.5 m/s) are presented. The tests are carried out with a drop hammer impact testing machine and then the structural responses under different impact velocities are analyzed. Additionally, the dynamic three-point bending simulation for specimens with different bonding areas, but the same reinforcement ratio is conducted. In this num

Abstract:

Effects of glue spread, adhesive kind and curing agent ratio on bonding quality of wood-FRP (Fiber Reinforced Plastic) interface were investigated to choose the optimal adhesive and condition of bonding wood-FRP composites. Two different kinds of epoxy resin and one kind of curing agent were used to bond wood-wood and wood-FRP samples with three different glue spread. Shear strength of samples were measured by compression shear test. The results indicated that bonding strength of wood-FRP sample with glue spread of 300 g/mm2 and curing agent ratio of 40% were the best, when using the same epox

In the present study, diffusion bonding of Cu/Cu was carried out at 750 °C for 60min under uniaxial pressureof 5-15MPa in vacuum. The joints were evaluated by Microtensile testing and Ultrasonic testing. The bond qualities were assessed by destructive testing (strength ratio) and nondestructive ultrasonic C–scan testing method.The bond quality obtained by both the methods is correlated in a view to use the C scan for regular testing. The optimum condition for obtaining the best bonding characteristics is reported. The joint obtained by diffusion bonding at 750 °C and a applied pressure of 15MP

Abstract:

For the purpose of researching the natural bonding behavior of different interfaces between steel and concrete in SRC structures, four specimens are designed to launch the monotonic push-out loading test. Each specimen is used to consider one case, including the bonding of the external flange, internal flange, web and whole cross-sections with the concrete. Failure process and modes of these specimens were observed during the test. Load-slip curves and ultimate bond strength are obtained and the bonding strength between different interfaces of steel and concrete was analyzed. The results show

Abstract:

To improve the joining efficiency of Bi-Sr-Ca-Cu-O ( BSCCO) superconducting tapes, a new diffusion bonding technology with a direct uniaxial pressing at high temperature was developed to join 61-filament tapes. It was observed that bonding parameters such as bonding pressure and holding time, significantly affected the critical current ratio (CCRo). A peak CCRo value of 89 % for the lap-joined tapes was achieved at 3 MPa for 2 h when bonding temperature was 800 °C. Compared with the conventional diffusion bonding technology, this new technology remarkably shortened the fabrication period and i

Abstract:

Electron energy loss spectroscopy is the only direct technique that can semi-quantitatively determine the nature of the bonding in carbon thin films. To quantify the sp2/sp3 bonding fraction, the spectrum taken from the film must be compared to that of a suitable known standard. The bonding fraction can be analysed by studying the K ionisation edge in the electron energy loss spectrum. A method for quantifying the sp2 bonding fraction in an amorphous carbon film has been described by Berger et al (1988), where the area of peak of the film is compared with that of graphite.

These multi-component alloys have very complex electronic structure, bonding and partial-charge distributions depending on the composition and strength of the local bonding environment.

The interface bonding behavior between the steel tube and the concrete of concrete-filled steel tube (CFST) blended with circulating fluidized bed bottom ash (CFB-BA) was investigated in this study. A total of 8 groups of CFSTs stub columns were prepared with different dosage of CFB-BA, water-binder ratio (W/B), and interface bonding length. A series of push-out tests were carried out to acquire the data representing the interface bonding behavior. The results show that the dosage of CFB-BA has a direct effect on interface bonding behavior of CFST. CFB-BA can improve the interface bonding beha

The results show that metallurgical bonding interface can be obtained with the optimal parameters. The metallurgical bonding interface is free of any discontinuities due to the elements diffusion across the interface.
