“…However, fusion welding and brazing welding are not suitable for joining Ti to Cu because brittle Ti-Cu intermetallic compounds (IMCs) are easily formed [3][4][5], which can seriously cause the mechanical properties of the Ti/Cu joint to deteriorate. Therefore, several kinds of welding techniques, such as explosive welding [6], friction welding [7], diffusion welding [8], and vaporizing foil actuator welding [9] were presented as methods for joining Ti to Cu plates. In recent years, with the rapid development of microelectronics and medical industries, joining of thin Ti foil to Cu foil may have a wide application prospect.…”

Abstract:In this paper a novel laser impact spot welding (LISW) method is described, in which a hump was formed on the flyer plate on the intended welding spot location by local pre-forming. When the flyer and base plates were placed together to perform welding, the two plates kept in contact over their entire surfaces except at the hump, where a local air gap was enough to guarantee the impact velocity and collision angle to achieve spot welding using laser pulse energy. The presented approach was implemented to join thin titanium foils to copper foils under low laser energy system. Joints with regular shapes were obtained. The microstructure in the weld interface was studied with scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). It was found that the jetting occurred at the central region of the weld spots due to oblique impact. Wave features were observed in the weld interfaces. The impact energy was found to have significant influence on the wave's characteristics. Moreover, SEM images and EDS analysis did not show apparent element diffusion across the weld interface. Besides, the lap shearing test was used to characterize the mechanical properties of the spot welded joints.

“…Both grinding and polishing processes were done with Struers LaboPol-5 at a velocity of 500 rev/min. The samples were etched with a chemical solution: 1% HF-1.5% HCl-2.5% HNO3-95% H2O [14]. Microstructure and morphologies of diffusion interfaces were examined by scanning electron microscopy (SEM, Philips XL30S FEG, Tustin, CA, USA).…”

Ti-6Al-4V alloy and commercially pure aluminum, which are commonly used in aerospace, medical, and automotive industries, are bonded by diffusion welding. Different welding parameters (560, 600, and 640 • C-0, 45, and 60 min-under argon shielding) are used in this process to make the materials more applicable in the industry. Here, the effects of parameters on the strength of joints were studied. The bonded samples were subjected to microhardness and tensile tests in order to determine their interfacial strength. The hardness values were found to decrease with increasing distance from the interface on the titanium side while it remained constant on the aluminum side. Maximum tensile strength was taken from the maximum bonding temperatures of 600 and 640 • C. A morphology examination of the diffusion interfaces was carried out with scanning electron microscopy.

This study presents a diffusion bonding process of commercially pure aluminum to Ti-6Al-4V alloy. Prepared samples were exposed to temperature of 560, 600 and 640 °C for the bonding time of 30, 45 and 60 min at the atmosphere of argon gas and non-argon. Diffusion bonding is a dissimilar metal welding process which can be applied to the materials without causing any physical deformations. The processed samples were also metallographically prepared, optically examined followed by Vickers microhardness test in order to determine joint strength. Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS) were used in this work to investigate the compositional changes in order to observe the influence of atmosphere shielding in the transition zone. The result of tests and analyses were tried to be compared with the effect of argon shielding. The significant influences have been observed in the argon shielding during diffusion bonding process.KEYWORDS: Argon gas shielding; Diffusion bonding; Dissimilar metal bonding; Solid-state bonding; Ti-6Al-4V alloy Citation / Citar como: Akca, E.; Gursel, A.

Este estudio presenta los procesos de difusión durante la unión de aluminio puro con la aleación Ti6Al4V. Se expusieron probetas a las temperaturas de 560, 600 y 640 ºC durante un tiempo de unión de 30, 45 y 60 min en una atmósfera en presencia y ausencia de gas argón. La unión por difusión es un proceso de soldadura entre metales distintos que puede ser aplicado a los materiales sin causar deformaciones físicas. Las probetas procesadas fueron preparadas también metalográficamente, examinadas por miscroscopía óptica, seguido de ensayos de microdureza Vickers para determinar el límite elástico. Se utilizó microscopía electrónica de barrido (SEM) y espectroscopía de energias dispersivas (EDS) para determinar los cambios en la composición y estudiar la influencia del argón como gas protector en la zona de transición. La influencia más importante se ha observado durante el proceso de difusión en estado sólido.PALABRAS CLAVE: Aleación Ti6Al4V; Argón gas protector; Difusión y unión; Unión de metales distintos; Unión en estado sólido ORCID ID: ORCID ID: Enes Akca
