Formation of equiaxed grains in selective laser melted pure titanium during annealing
Cheng-Lin Li,Chang-Shun Wang,P.L. Narayana,Jae-Keun Hong,Seong-Woo Choi,Jae Kim,Sang Won Lee,Chan Hee Park,Jong-Taek Yeom,Q.S. Mei +9 more
TL;DR: In this paper, the formation of equiaxed grains occurred at two types of microstructural features, acicular α and irregular massive (α′m) martensite, which exhibited different sizes, morphologies, and contained different types of substructures under SLM as-fabricated condition.

Novel eutectoid Ti-5Ni alloy fabricated via direct energy deposition
P.L. Narayana,Jae Kim,Sang Won Lee,Jong Woo Won,Chan Hee Park,Jong-Taek Yeom,N.S. Reddy,Jae-Keun Hong +7 more
TL;DR: In this paper, the tensile properties of the as-fabricated and the heat-treated alloy remarkably improved compared with the other conventionally processed eutectoid Ti-Ni binary alloys.

Porosity features and gas permeability analysis of bi-modal porous alumina and mullite for filtration applications
Rizwan Ahmad,Muhammad Shoaib Anwar,Jae Kim,In-Hyuck Song,Syed Zaighum Abbas,Syed Ahmad Ali,Fahad Ali,Jamil Ahmad,Hasan Bin Awais,Mazhar Mehmood +9 more
TL;DR: In this article, a bimodal pore structure was observed by combining conventional sacrificial template and partial sintering methods, and the pore characteristics and gas permeation properties of alumina/mullite specimens sintered at different temperatures.

High temperature isothermal oxidation behavior of electron beam melted multi-phase γ-TiAl alloy
P.L. Narayana,Jae Kim,Dae Won Yun,Seung-Eon Kim,N.S. Reddy,Jong-Taek Yeom,Dongyi Seo,Jae-Keun Hong +7 more
TL;DR: In this paper, an additively manufactured γ-TiAl alloys with the help of electron beam melting (EBM) for the first time and tested for 100h over a temperature range of 800-°C-1000°C; this was aimed at investigating its isothermal oxidation kinetics.

Effect of silica on flexibility of yttria-stabilized zirconia nanofibers for developing water purification membranes
TL;DR: In this paper, the effect of ceramic precursor concentrations [tetraethyl orthosilicate (TEOS) and zirconium (IV) propoxide (ZrP)] on improving the flexibility of YSZ/silica nanofibers was investigated.
