Abstract
This study investigates the refinement of 3D interconnected Fe₈₀Cr₂₀-Mg heterostructure composite material fabricated via Liquid Metal Dealloying (LMD) followed by High-Pressure Torsion (HPT) process. The LMD process was executed using two distinct thicknesses of the (Fe₈₀Cr₂₀)₇₀Ni₃₀ precursor alloy, specifically 0.8 mm and 1.5 mm, which were immersed in an 800..... More

Abstract
This study aimed to evaluate microstructural changes in various locations of an induction heat treated low-alloy steel in a quantitative manner. A commercially produced ring gear sample of a SNCM 439 steel was prepared. The specimens for experiments were obtained from the gear sample after a surface induction hardening heat..... More

Abstract
This study aims to comprehensively understand the effects of changes in the chemical composition and size of attached particles on the resulting assimilation characteristics during the sintered ore production process. By evaluating the penetration depth and changes in the chemical composition in the assimilated region of the iron ore and..... More

Abstract
This study investigated changes in electrical and mechanical properties, as well as the high humidity reliability of 18 μm-diameter silver alloy wires with palladium contents of 1.1, 2.5, 3.0, and 4.0 wt%, for semiconductor packaging. We also compared the formation of Free Air Ball (FAB) and the high humidity reliability..... More

Abstract
Recently, due to energy shortages and environmental pollution caused by the continued use of fossil fuels, there is a growing need for renewable sources to replace fossil fuels. ZIF-67 has a porous structure, a large surface area, high thermal and chemical stability, and a narrow band gap, so it is..... More

Abstract
Octahedron-shaped zinc stannate (Zn₂SnO₄) crystals and hexagonal cylinder-like ZnO crystals were synthesized through a simple thermal evaporation method under uncomplicated conditions of air atmosphere. The Zn₂SnO₄ octahedrons were grown by heating a mixture of ZnS and SnO powders, and the ZnO hexagonal cylinder-like crystals were fabricated by heating mixtures of..... More

Abstract
The effects of annealing temperature and thermal cycle conditions on the adhesion characteristics of non-cyanide Si/sputter TiW/sputter Au/Au bump structure were systematically investigated using a shear test. No intermetallic compound was observed at the TiW/Au interface at all annealing temperatures, and voids formed between the TiW and Au bump interface..... More

Abstract
Transparent TiO₂ single layer and TiO₂/Ag/TiO₂(TAT) tri-layer films were deposited by DC and RF magnetron sputter on a polyimide substrate at room temperature. During the TAT deposition, the thickness of the TiO₂ layer was kept at 20 nm, while the Ag interlayer was varied as 10, 15, 20 nm to..... More

Abstract
The semiconductor and display industries employ microfabrication and high-density technology to enhance the performance of IT products. Current micro-patterning methods primarily rely on photolithography. However, photolithography is a complex and expensive process, with limited freedom of pattern design, and involves dry etching methods that use toxic substances, which are harmful..... More
