“…Ti was prominent near the interface as shown although it existed a little across the interface. A thick layer of Cu 2 Ti is present near the Ti-6Al-4V which is related to the diffusion of Ti from Ti-6Al-4V and Cu from the filler metal to form an excellent bond [4]. e IMC thicknesses of Ag-Cu-Ti filler (x � 0 and 0.03) are 18.5 and 22.8 μm.…”

“…It is always a practical challenge to bond these ceramic materials directly due to a wide difference in physicochemical and mechanical properties of ceramics and metals that imposes a great challenge in microjoining operations [2]. For this purpose, various popular brazing fillers are already developed where the most popular ones are eutectic Ag-Cu or Ag-Cu-Ti alloys as reported in the past [3,4]. However, with regard to complex geometry, the thickness of IMCs, and cost, each filler is unique and has limitations of its own [5].…”

“…In such case, the selection of a superior filler metal is required for high reliability of brazed ceramic joints. If we inspect previous literatures, we see two major issues that are needed to be minimized in ceramic brazing, such as wetting of the contact surfaces and the stress development caused by the mismatch in mechanical and thermal properties of two contact materials that depend on the deformation characteristics of the filler used [1][2][3][4][5].…”

In this work, we have attempted to develop the Ag-Cu-Ti filler for bonding ZrO 2 to Ti-6Al-4V. e CeO 2 nanoparticles were reinforced in the eutectic Ag-Cu-Ti filler via mechanical mixing and melting route. Furthermore, the brazeability, microstructure, and mechanical behavior, as well as brazing performance of the ZrO 2 /Ti-6Al-4V joints, were assessed. e wettability of the Ag-Cu-Ti matrix was increased from 89 to 98% on Ti-6Al-4V and from 83 to 89% on the ZrO 2 substrate after the addition of 0.05% CeO 2 . Also, there was a depression in the melting point of the composite fillers up to 3°C. e microstructure consists of Cu-and Ag-rich phases and Cu-Ti intermetallic compounds (IMCs). e joint shear strength was improved with the addition of CeO 2 up to 0.05 wt.% in the matrix. It was inferred that, for an excellent brazing performance of the ZrO 2 /Ti-6Al-4V joint, the optimum amount of CeO 2 should be 0.05 wt.% in the Ag-Cu-Ti matrix.

The joining of various parts in engineering applications such as automotive components, aircrafts, medical implants, sensor devices, interconnections etc., are a great concern nowadays. Various types of low melting point fillers, braze and alloys have been also developed but problem of crack generation and failures are not satisfactorily treated. This paper reviews some of the developments in traditional and modern joining techniques in automotive joining and welding. Currently, joining of composites is attracting researchers for weight reduction and economy. There are many practical techniques for joining metals and ceramics to themselves and to dissimilar materials. An overview of various processes of joining metal-metal, ceramic-metal and composites, factors affecting joining and approaches used to improve the brazed joint structures are presented here. In addition, new modifications in welding and brazing processes are outlined for further directions.

“…The addition of several active elements can also contribute to various IMCs, Cu-Ti, Cu 3 Ti, Ti 3 SiC 2 , etc. Due to these brittle IMCs, the joint cannot be operated at high temperatures [6][7][8][9][10][11][12]. Therefore, the key factor to braze ceramics to metals is to look for new fillers for brazing where active elements (Ti, Zr, etc.)…”

The aim of this chapter is to provide a basic understanding of the metal-ceramic joints and high-entropy alloy (HEA) research in microjoining applications. We will first overview the issues in metal-ceramic brazing and solutions to overcome those issues using various fillers. Various approaches are available for joining ceramic to metallic materials. One approach will be to look for brazing alloys with the so-called high-entropy characteristics which exhibit a solid solution phase. The conventional alloy design and arc melting, Bridgman solidification, and advanced powder metallurgy techniques will be studied, including high-energy ball milling (HEBM) for the mechanical alloying process, and hot-press and spark plasma sintering (SPS) techniques are utilized for improved densification and phase transformation. We also summarize the various thermodynamic relations to obtain the high-entropy phase and present future possibilities of high-entropy alloys in microjoining research at the later stage of this chapter.
