Microstructure Analysis of Ni-Al Compositionally Gradient Alloy

Gradient Distribution of Martensite Phase in Melt-Spun Ribbons of a Fe-Ni-Ti-Al Alloy

Metallographic, X-ray diffraction and magnetometric analysis were used to study the regularities of martensitic transformation in melt-spun ribbons of a Fe - 28 wt. % Ni - 2.1 wt. % Ti - 2 wt. % Al - 0.05 wt. % C alloy. The substantial differences in volume fractions of the martensite phase in local regions of thin melt-spun ribbons of the alloy are related to the size effect of the transformat...

Compositionally Modulated Alloy Synthesis

IPTME, Loughborough University of Technolom, LEI 1 3TU, UK " 9 7 z777$ __ Abstract P.9 F" Compositionally modulated alloy (CMA) coatings can be synthesised electrochemically The technique is performed by electrodeposition from a plating bath usually containing two different metal ions The alloy modulation is attained through pulsing the voltage or current between two or more pre-optimised level...

Microstructure Modelling of Hot Deformation of Al-1%Mg Alloy

This study presents the application of the finite element method and intelligent systems techniques to the prediction of microstructural mapping for aluminium alloys. Here, the material within each finite element is defined using a hybrid model. The hybrid model is based on neuro-fuzzy and physically based components and it has been combined with the finite element technique. The model simulate...

CHARACTERIZATION OF THE MICROSTRUCTURE OF THE COMPOSITIONALLY COMPLEX ALLOY Al1MoNb1Ta0.5Ti1Zr1 (POSTPRINT)

Crystallization kinetics of Al±La±Ni amorphous alloy

The crystallization kinetics of an Al89La6Ni5 amorphous alloy were studied by thermal analysis. Both continuous heating and isothermal DSC traces showed that the Al89La6Ni5 amorphous alloy undergoes a two-stage crystallization process upon heating. The ®rst transformation, in which fcc-Al precipitates from the amorphous matrix, is a nucleation and three-dimensional di€usion-controlled growth pr...
