“…The joint strength was further analyzed by the typical fractography and fracture path diagram, as shown in Figure . According to the literature, the microhardness of Cu 2 InTi and CuTi is about 386 [ 27 ] and 298 HV, [ 28 ] respectively, which indicates that both Cu 2 InTi and CuTi are brittle phases. At 720 °C, the concentrated and highly brittle Cu 2 InTi and CuTi intermetallic compounds in the joint lead to residual stress accumulation, leading to crack initiation and propagation.…”

The joining of Si3N4 and Mo using Ag–Cu–In–Ti active filler alloy with the brazing temperature ranging from 720 to 860 °C for 10 min is investigated in this article. The correlation between the joint strength and the microstructures of the brazed joints is discussed. In the results, it is shown that the activity of Ti is different at different temperatures, and thus the degree of diffusion of Ti to the interface is different. The activity of Ti gradually increases as the brazing temperature increases, and more Ti atoms diffuse into both sides of the base materials, resulting in a progressively thicker TiN + Ti5Si3 reaction layer on the Si3N4 ceramic side. Between 720 and 860 °C, the shear strength of the joint first increases and then decreases with brazing temperature. The maximum shear strength (223 MPa) is obtained at 830 °C.

“…In the same vein, stress cracking due to sulphide presence in high and low strength alloys (carbon steel C110) is attributed to hydrogen absorption process. It was reported by Liu and Case [53] that the experimental result of electrochemical impedance indicated that hydrogen sulphide was suppressed by chloride ion presence especially in the presence of NaCl. Thus, chloride ion played a great role in reducing the impact of sulphide stress cracking activities.…”

“…To this end, Liu and Case [53] investigated effect of hydrogen sulphide on carbon steel sample to determine its susceptibility to sulphide stress cracking. The study focused on the hydrogen absorption based on the concentration of the hydrogen sulphide and assessment of sulphide stress cracking as a result of low strain and the relationship between the hydrogen absorbed and the sulphide stress cracking.…”

Alloy steel is known to be different from carbon steel due to the presence of the alloying element in varying compositions which is usually done for the purpose of modifying and improving the performance of the steel. However, a major problem with the alloy steel is that it usually exhibits different behavior in terms of the microstructures and the mechanical properties, especially, in sulphide environment. Thus, this study focused on the different microstructure of alloy steel and their performance in different environment with strong emphasis in sulphide environment. It was established in the study that a major problem of alloy steel in hydrogen sulphide environment is the sulphide stress cracking which is attributed to the presence of hydrogen and its absorption by the alloy steel. Hence, this study provides a potential guide and information on the capacity of the grades of alloy steel that can thrive in sulphide environment.

“…Cemented carbide is a composite material consisting of refractory carbide (e.g., WC, TiC, and TbC) and metal phase (e.g., Fe, Co, and Ni). Owing to its high strength, high hardness, excellent wear resistance, high-temperature resistance, and corrosion resistance, cemented carbide has been used in a wide range of industries, such as tools, mold, automobile, aerospace, oil exploitation, machinery and equipment manufacturing, rail transit, and electronic information [1][2][3][4][5][6][7]. Tungsten carbide-cobalt (WC-Co) is one of the most important cemented carbide materials.…”

Tungsten carbide-cobalt (WC-Co) cemented carbide has a wide range of application prospects in a wide range of industries because of its high strength, high hardness, excellent wear resistance, high temperature resistance, corrosion resistance, etc. Additive manufacturing (AM) makes it possible to fabricate geometrically complex tools compared to traditional manufacturing techniques. However, the preparation of high solid loading, superior stability, and optimal curing thickness of WC-Co cemented carbide slurry remains challenging for creating cemented carbide components with complex shapes via stereolithography. In this work, the dispensability, stability, and curing thickness of WC-Co cemented carbide slurry were systematically investigated. The suitable WC-Co (94-6wt.%) cemented carbide slurry for stereolithography was successfully achieved by ball milling under appropriate process parameters, and the complex-shaped WC-Co (94-6wt.%) cemented carbide green bodies were fabricated. This work aims to provide a reference for additive manufacturing of near-net-shape WC-Co cemented carbide parts by stereolithography.
