Abstract
The effects of oxygen content on the β to α phase transformation of the Ti-5Al-2.5Fe alloy during continuous cooling were investigated by varying the oxygen content between 0.08 – 0.41 wt%. Dilatometer tests were performed at cooling rates of 0.05 – 100 ℃/s combined with microstructure observation to examine phase..... More

Abstract
A new Ni based superalloy with high fatigue resistance and fine grain was considered as a material for high-pressure buckets in fossil fuel power plants. Since such buckets are usually exposed to extreme operating conditions, low cycle fatigue tests were conducted to understand the microstructure evolution of the material during..... More

Abstract
Mill-annealed Ti-6Al-4V (Ti64) sheets were formed into rectangular shaped pans with two square recesses by the superplastic forming (SPF) technique under high pressure using commercial grade argon gas. The SPF process induced a significant decrease in the tensile ductility and high cycle fatigue (HCF) resistance of the Ti64 alloy. The..... More

Abstract
The wetting behavior of liquids on solid surfaces is important in the study of surfaces and interfaces. In this study, the wetting behavior of deionized (DI) water and hexadecane on fluorinated and micro-patterned polymer surfaces was investigated. The sample surfaces were processed by spray coating and thermal imprinting, respectively. The..... More

Abstract
Since their development in the 1970s ZrO₂ ceramics have been shown to be promising alternative materials for total hip arthroplasty (THA) and total knee arthroplasty (TKA). However, ZrO₂ is so brittle that in vivo failure can result from fracture of the ceramic femoral head and fracture of the ceramic acetabular..... More

Abstract
In the photovoltaic industries, the main technique of metallization is screen printing with silver pastes, due to its simple and quick process. However, the high price of silver paste is one of the barriers to the producing of low cost solar cells. Consequently, a primary target in photovoltaic research is..... More

Abstract
In this paper, the soft magnetic properties and compaction density of Fe-Si-B-Nb-Cu nanocrystalline powder cores, mixed with two kinds of permalloy powders (Ni₇₀Fe₃₀ or Ni₅₀Fe₅₀), have been closely studied. Permalloy powders having an average diameter of 4μm were added in the range of 5 to 15 wt%, and the powder..... More

Abstract
We report the effects of Sb content on the charge transport and power factor of Bi_2-xSb_xTe₃(1.56 ≤χ≤ 1.74) compounds prepared by hot pressing. From the temperature-dependence of the electrical conductivity, it was found that the charge transport in the compounds was predominantly governed by acoustic phonon scattering, and additionally affected.....

Abstract
Abstract: In this work, Zn(BH₄)₂ was added to improve the hydrogen-storage properties of MgH₂. A 99 wt% MgH₂+1 wt% Zn(BH₄)₂ sample was prepared by milling in a planetary ball mill in a hydrogen atmosphere. The proportion of the added Zn(BH₄)₂ was small (1 wt%) in order to increase hydriding and..... More

Abstract
Austenitic stainless steels have excellent mechanical property and corrosion resistance, and are for these reasons used in demanding applications such as power plant, nuclear reactor and off-shore plant. Especially, austenitic stainless steel 304 (STS304) is mainly used as a pipe material in nuclear power plants. Submerged arc welding (SAW) is..... More
