Determination of total titanium in titanium metal and titanium tetrachloride
BUNSEKI KAGAKU, 1961 金属チタンおよび四塩化チタン中の全チタンの定量法につき,簡易化と迅速化の見地から容量法を詳細に研究し,つぎの諸方法を確立した.金属チタンは試料をフッ化水素酸と硫酸にとかし,ホウ酸を加えて液状亜鉛アマルガムで還元する.のち四塩化炭素を加えて液状亜鉛アマルガムを分離し,還元液を硫酸第二鉄アンモニウム溶液で滴定し全チタンを求める四塩化チタンは試料を注射針付き注射器で塩酸に注入溶解させる.のち試料がバナジウムを含まない場合は金属チタンと同様に還元,滴定する.またバナジウム含有の場合は塩酸溶液に硫酸と過酸化水素水を加え硫酸白煙ののち液状亜鉛アマルガム還元,過マンガン酸カリウム滴定を行ない別に求めたバナジウム含量により補正を行なう.分析精度を変異係数(σ%)で示せば金属チタンで約0.1%,四塩化チタンで約0 ...

Advanced Engineering Materials, EarlyView.HEA interlayers offer a versatile route for joining high‐performance structural materials. Their compositional and structural design regulates interfacial reactions, suppresses brittle IMCs, and improves metallurgical bonding. Sandwich interlayers further integrate defect healing with precipitation strengthening, enabling improved strength–ductility ...

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.

Advanced Engineering Materials, EarlyView.Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Effect of VC additions on the microstructure and mechanical properties of TiC-based cermets
Materials Research Express, 2020 VC is important carbide additive and has a similar crystal structure with TiC. In this study, the effect of adding VC amounts at content levels of 1–8 wt% on the microstructure evolution and mechanical properties of TiC-based cermets is examined.

Advanced Engineering Materials, EarlyView.This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Advanced Engineering Materials, EarlyView.A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.
