1Effect of Rare Earth and Transition Metal Elements on the Glass Forming Ability of Mechanical Alloyed Al–TM–RE Based Amorphous Alloys显示文摘The present work aims to compare the amorphous phase forming ability of ternary and quaternary Al based alloys(Al86Ni8Y6, Al86Ni6Y6Co2, Al86Ni8La6 and Al86Ni8Y4.5La1.5) synthesized via mechanical alloying by varying the composition, i.e. fully or partially replacing rare earth(RE) and transition metal(TM) elements based on similar atomic radii and coordination number. X-ray diffraction and high resolution transmission electron microscopy study revealed that the amorphization process occurred through formation of various intermetallic phases and nanocrystalline FCC Al. Fully amorphous phase was obtained for the alloys not containing lanthanum, whereas the other alloys containing La showed partial amorphization with reappearance of intermetallic phases attributed to mechanical crystallization. Differential scanning calorimetry study confirmed better thermal stability with wider transformation temperature for the alloys without La.Ram S.Maurya Tapas Laha 2015Journal of Materials Science & Technology2015,31,11:3
2莫代尔混纺纬编针织物的尺寸特性研究显示文摘分别研究了莫代尔/棉、莫代尔/黏胶和莫代尔/聚酯混纺针织物在坯布、漂白和后整理阶段的尺寸特性,各混纺织物的纱线密度有2种:24 tex和20 tex,莫代尔质量分数有3种:30%、50%和70%。对线圈长度、线圈密度和紧度系数也进行了研究,研究发现:与细纱相比,粗纱具有更高的线圈密度和紧度系数;与坯布织物相比,成品布具有更高的线圈密度和紧度系数;与30%和70%莫代尔混纺针织物相比,50%莫代尔混纺针织物具有更高的线圈密度和紧度系数。与棉混纺织物和黏胶混纺织物相比,聚酯混纺织物在任何情况下都具有更高的线圈密度和紧度系数。研究表明,纤维种类、莫代尔质量分数和湿松弛处理对织物的尺寸特性有显著影响。S.Maurya D.Sharma 海文清(译) 毕思伊(校) 2022国际纺织导报2022,50,10:0
