Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing
Advanced Engineering Materials, EarlyView.This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam
Advanced Engineering Materials, EarlyView.Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

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 ...

Creep Properties and Deformation Mechanism of Additively Manufactured NiAl‐CrMo Composites
Advanced Engineering Materials, EarlyView.Additively manufactured NiAl‐CrMo composites contain numerous interfaces and cell boundaries that control their creep response. At 700°C under high applied stress, creep is dominated by dislocation‐controlled power‐law mechanisms. At 800°C–900°C and lower stresses, creep is primarily diffusion‐controlled along cell boundaries.

Production of MgO/TiC Composites From MgO‐C Recyclates Using Spark Plasma Sintering
Advanced Engineering Materials, EarlyView.Using the spark plasma sintering technique, MgO/TiC composites are manufactured from recycled MgO‐C refractories stemming from the steel production that were mixed with titanium powder. This article shows, how the size of the Ti grains and their distribution in the powder mixture affect the local carbon concentration in TiC.
