Abstract
Although the laser scan strategy does not affect the energy density of laser-based additive manufacturing, changes in laser scan direction critically influence the residual stress and microstructure of metallic components. However, only a limited number of studies have investigated the role of laser scan strategy on the microstructure and mechanical..... More

Abstract
Laser Directed Energy Deposition (L-DED) is a notable additive manufacturing method in which metal powder is sprayed through a nozzle and then consolidated layer by layer using a laser. Unlike other additive manufacturing processes, DED has fewer constraints on the size of the fabricated parts, making it advantageous for the..... More

Abstract
Tantalum and tantalum alloys, which have superior thermal properties, including a high melting temperature, low specific heat, low thermal conductivity, and high density, are promising candidates for highperformance parts exposed to high temperatures and hazardous environments in aerospace, defense, and other industries. However, those alloys are hard to cut and..... More

Abstract
The weldability and the relationship between microstructure and tensile properties at 298 and 110 K produced by laser-arc hybrid welding (LAHW) in high-Mn steel welds were thoroughly investigated. In the laser zone of LAHWs using filler wire, more Mn vaporization in the laser zone was observed than at the arc..... More

Abstract
Bismuth antimony telluride (Bi-Sb-Te)-based alloys remain the dominant choice for near-roomtemperature thermoelectric cooling applications. One of the most studied approaches to improve the thermoelectric performance of Bi-Sb-Te alloys has been a nanostructuring strategy, to suppress the lattice thermal conductivity. This study investigates the impact of incorporating reduced pyrolyzed Pd acetate..... More

Abstract
Hard carbon is widely recognized as the most promising anode material for sodium-ion batteries (SIBs). Hard carbon is a non-graphitizable carbon characterized by a turbostratic structure with disordered stacking of carbon layers, each consisting of a few nanometer-sized graphene layers. It remains difficult to graphitize even at temperatures above 2500°C...... More

Abstract
N-type Mg₃Sb_2-xBi_x materials are expected to replace n-type bismuth telluride because they are more abundant in the Earth's crust and lower in cost. However, the metallization process of this material, which is essential to develop modules, has been relatively under-researched. According to the literature, one-step sintering process based on powder..... More

Abstract
Plasma thermal spray coating method was applied to prepare a high performance neutron shielding layer for various applications such as nuclear spent fuel transportation and storage containers and experimental research reactors. In this study, layers with various compositions of a gadolinium oxide neutron absorber and a nickel alloy binder on..... More

Abstract
Ti alloys are difficult to machine, accounting for 50-75% of the final component price, necessitating urgent improvements in machinability to increase their demand in several fields. This study found that adding small amounts of Ce (0.1-2.0wt.%) significantly improves the machinability of Ti-6Al-4V alloy. Here, we systematically analyzed microstructural changes due..... More
