To address interfacial regulation in low-pressure heterogeneous joining of titanium alloys and titanium matrix composites, diffusion bonding experiments were conducted on TC4 alloy and TiB w /TC4 composites at 930 °C under a low pressure of 10 MPa. The effects of holding time on interfacial microstructure evolution and mechanical properties were investigated. The results show that, under low bond…

The use of flexible compositional ranges is emerging as a recycling-oriented alloy design strategy that accommodates mixed-scrap variability while maintaining targeted performance. Here, we experimentally validate a compositionally flexible, scrap-tolerant austenitic stainless steel design using controlled laboratory remelting of realistic stainless-steel scrap mixtures, where mixed scraps introd…

ABSTRACT Low-temperature reduction disintegration is a critical factor governing the blast furnace burden performance of sinter. In this study, ultrasonic attenuation was evaluated as a nondestructive parameter associated with reduction-induced microstructural damage in synthetic Fe 2 O 3 -CaO-SiO 2 -MgO-Al 2 O 3 sinter systems. Phase evolution was analyzed by XRD and thermodynamic calculations, …

This study examines the structural and microstructural performance of Dendrocalamus asper laminates bonded with a castor-oil-based polyurethane adhesive, aiming to assess how two distinct milling methodologies through laminate rectification (RRLB) and partial preservation of culm curvature (RALB), influence their physical characteristics, mechanical properties, and the quality of the bonded inter…

The influence of fibre hybridization on the multifunctional performance of jute–banana fibre reinforced bio-epoxy composites was experimentally evaluated to assess their suitability for lightweight structural and acoustic applications. Alkali-treated jute and banana fibres were used as reinforcements, and composite laminates with different hybrid ratios were fabricated while maintaining a constan…

As a promising candidate of Generation IV nuclear energy system, the molten salt reactor (MSR) has attracted growing attention due to its advantages regarding safety and thermal efficiency. However, the harsh operational environments in MSRs, combining high operating temperatures, intense neutron irradiation, and direct exposure to highly corrosive media, pose critical challenges to the durabilit…

Simultaneously controlling the dimensional accuracy and mechanical properties of double-layered thin-walled components made of dissimilar titanium alloys poses a significant challenge. Focusing on the double-layered thin-walled component of TA15 and TC2 titanium alloys, this paper proposes a hot forming with in-die aging process (short for HFA), which comprises three steps: solution treatment at …

Surface wettability plays a critical role in governing interfacial phenomena of nuclear fuel cladding, particularly under boiling and corrosion-driven environments. In this study, we introduce a surface engineering process to render the Zirlo cladding alloy superhydrophilic, addressing its inherently limited interfacial performance in coolant environments. A nanoporous ZrO 2 oxide layer was forme…

The incorporation of alloying elements into SnAgCu (SAC) environmentally friendly electronic interconnection materials provides an effective strategy for tailoring thermal behavior, microstructural evolution, mechanical properties and interfacial reliability.

: Aluminum alloy 2219 (AA2219) friction stir welding (FSW) joints for rocket propellant tanks are subjected to cryogenic tensile loading, and crack initiation during deformation plays an important role in the evaluation and prediction of their service performance. To investigate the crack initiation behavior of AA2219 FSW joints at 77 K, a crystal plasticity finite element model incorporating har…

: High Ce content in Nd-Ce-Fe-B magnets introduce the low magneto-crystalline anisotropy Ce 2 Fe 14 B phase and the high-melting CeFe 2 phase, which act as barriers to heavy rare earth (HRE) grain boundary diffusion. Conventional approaches attempt to eliminate or modify this phase to mitigate the hindrance. However, this work instead employs a preheating treatment (PHT) to tailor its distributio…

Solid-state hydrogen storage is regarded as a promising technology for future hydrogen energy systems due to its high safety, high volumetric hydrogen density, and reversible hydrogen storage capability. Nevertheless, improving the activation behavior of TiFe-based alloys remains a major challenge for their practical application. In this context, TiFe and Ti 46 Fe 46 Nb 2.5 Zr 2.5 V 2 Cr 0.5 Ni 0…

: The concept of high-entropy alloy (HEA) was first proposed in 2004, and the basic principles, based on four core effects, were scientifically confirmed in 2006. The high-entropy effect, severe lattice distortion, sluggish diffusion, and cocktail effect, serve as a strong foundation for the rational design of advanced materials. By exploiting these phenomena, materials selection strategy can be …
