With the continuous improvement of lightweight requirements for equipment, Mg alloys are increasingly widely used, and their joining with traditional steel materials is essential. However, Mg and Fe have almost no solid ...

Butt welding between SLM-formed AlSi10Mg and rolled 6061 alloy (T6 state) was conducted by the tungsten inert-gas arc welding(TIG) method. The microstructure and mechanical properties of TIG welded joints under different...

A study on the microstructure, mechanical properties, and heat treatment process of pure tantalum TIG joints was conducted. Industrial computed tomography (CT), OM, and SEM were used to characterize the microstructure of...

It has been shown that rolling an Fe–15Mn–5Si–9Cr–5Ni (wt.%) alloy at 800 °C followed by annealing at 650 °C gives a structure – a high density of stacking faults and enough austenite hardness – that promot...

A blowout in a 14 in. diameter, 1/4 in. thick API 5L X46 oil pipeline was due to the sudden propagation of a fracture at the longitudinal Electrical Resistance Welding (ERW) weld. The cracks initiated from small hook cra...

Abstract With the growing interest in utilizing Mg and austenitic stainless steel (ASS) in the automotive sector, joining them together in three-sheet configuration is inevitable. However, achieving this task presents co...

To meet the requirements of precision and high-performance diffusion bonding for titanium alloy structures, pure graphite was used as the position limitation block. Diffusion bonding tests of TA15 titanium alloy samples ...

Porous ceramics are widely used in fields such as heat insulation, filtration, sound absorption, and catalysis due to their good chemical stability, as well as the high permeability and large specific surface area of por...

Abstract Biological soft tissues manipulation, including conventional (mechanical) and nonconventional (laser, waterjet and ultrasonic) processes, is critically required in most surgical innervations. However, the soft t...

Inconel 625 alloy exhibits excellent high-temperature performance and corrosion resistance and is frequently used as a protective coating material for oxidation resistance, corrosion resistance, and wear resistance. Howe...
