Oxide dispersion strengthened (ODS) alloys exhibit excellent mechanical properties due to fine oxide dispersion, but they have great limitations utilizing powder fabrication via alloying. Therefore, this study examined the alloy composition and process that can fabricate ODS titanium (Ti) in situ through a gas atomization method. The content of oxide, which dissolve molten Ti during melting precipitate inside powders cooling atomization, were derived thermodynamic calculations. + 1 wt%...
Archaeological excavations in Buyeo had revealed Bronze vessels interred within a hole the building at Gwanbuk-ri site. These bronze are dated to Unified silla period (9-10th centuries). To identify vessels’ manufacturing technology, metallurgical analyses were carried out using Optical Microscopy, SEM-EDS and EPMA. The results allowed reconstruction of process silla. It proved that manufactured with Cu-Sn alloy varying tin contents, which may be related application uncontrolled procedures...
Metallographic analysis of microstructure, chemical composition and hardness was carried out on 7 bronze vessels from Mangduksa temple site in Gyeongju. Result show that the technology divided into casting forging followed by quenching. Tin contents bronzes were around 11∼14 wt%, about 21∼23 wt% tin. Kundika dish Cu-Sn-Pb alloys 5 bowl samples produced using Cu-Sn binary alloy materials. These manufacturing applied different depends Sn contents. Also 4 bowls approximately 20 tin manufactured...
Microstructural examination of the Nb-Si-B alloys at Nb-rich compositions is performed. The corner system favorable in that constituent phases are Nb (ductile and tough phase with high melting temperature) T2 (very hard intermetallic compound oxidation resistance) which good combination for temperature structural materials. samples containing near Nb- Si-B ternary prepared by spark plasma sintering (SPS) process using powders. bulk made arc furnace slug powder compact. was subsequently...
The very high temperature reactor (VHTR) materials R&D started as an objective of the development key technologies for a nuclear hydrogen production funded by Korea government in 2006. We are performing 5 components: pressure vessel (RPV), reactor/process intermediate heat exchanger (IHX) and hot gas duct, control rods component, reflector support structures core region sulfur-iodine (SI) process. scopes our works focused on material screening/selection qualification, codifications...
<p>Additive manufacturing (AM) is defined as the manufacture of three-dimensional tangible products by additively consolidating two-dimensional patterns layer layer. In this review, we introduce four fundamental conceptual pillars that support AM technology: bottom-up factor, computer-aided distributed and eliminated factor. All factors work together; however, business strategy technology optimization will vary according to main factor emphasize. parallel paradigm shift toward mass...
Fabrication oF aluminum matrix composite reinForced with al 0.5 cocrcuFeni high-entropy alloy particlesThe dispersed high entropy were developed by stir casting involving the powder-in-tube method.First, CoCrCuFeni (Hea) powder was made mechanical alloying, and extruded in a tube-type container to form Hea precursor.The precursor then via casting.as result, Fe-Cr-ni based phases uniformly formed matrix, revealing ~158, 166, 235% enhancement of tensile strength incorporating 1, 3, 5 wt%...
