Structural Insights in the β to α Phase Transformation of the U–1 wt.%Ga–0.2 wt.%Fe Alloy
Springer Science and Business Media LLC - Tập 3 - Trang 454-459 - 2014
M. Aizenshtein, D. Hamawi
β-U could be metastably retained at room temperature when alloyed with various elements such as gallium. Since iron is a common impurity, we investigated two different kinetic processes which occurs simultaneously; one is the $$ \beta \to \alpha $$ ...... hiện toàn bộ
Exploring the Effect of Ni as an Impurity on Fe-Rich Phases in Simulated Direct Chill Casting Al–Fe-Si Alloys
Springer Science and Business Media LLC - Tập 11 - Trang 724-735 - 2022
E. A. Elsharkawi, D. MacNeil, B. Chouraqui, X.-G. Chen
The influence of nickel at concentrations from 100 to 560 ppm on the microstructure of Al-0.15Si-0.3Fe-xNi alloy has been investigated. A Direct Chill (DC) simulator is used in the current study to simulate the actual cooling rate occurring in a commercial DC casting ingot. The main iron-rich phases observed in the microstructure of the base alloy are AlmFe, Al3Fe, α-AlFeSi, and globular AlFeSi pa...... hiện toàn bộ
Development of Ti6AlFe Alloy and its Microstructural Transformation During Synthesis and Subsequent Thermo-Mechanical Treatment
Springer Science and Business Media LLC - Tập 11 - Trang 569-579 - 2022
Ayad Omran Abdalla, Astuty Amrin, Khairur Rijal Jamaludin, Meysam Toozandehjani
A compositional modification was initially carried out in Ti-6Al-4V alloy by substitution replacement of vanadium (V) by iron (Fe) as a β-stabilizing alloying element in order to develop Ti6Al(1-3)Fe alloys. Afterwards, Ti6Al(1-3)Fe alloys underwent rolling at 800 °C followed by solution heat treatment at 900 °C. Microstructural characterization reveals that Ti6Al(1-3)Fe alloys contain a lamellar ...... hiện toàn bộ

Microstructural Evolution and Mechanical Properties of Friction Stir Welded Dissimilar AA2014-T6 and AA7075-T6 Aluminum Alloy Joints
Springer Science and Business Media LLC - Tập 4 - Trang 178-187 - 2015
V. Saravanan, Nilotpal Banerjee, R. Amuthakkannan, S. Rajakumar
The dissimilar AA2014-T6 and AA7075-T6 aluminum alloy butt joints were made by friction stir welding with different process parameters. Friction stir welding is an efficient technique to join dissimilar aluminum alloys when compared to other traditional techniques. This paper aims to address the effect of various parameters, in particular the welding speed and shoulder diameter to pin diameter rat...... hiện toàn bộ

New Metallographic Method for Estimation of Ordering and Lattice Parameter in Ternary Eutectic Systems
Springer Science and Business Media LLC - Tập 2 - Trang 140-147 - 2013
A. Dennstedt, L. Ratke, A. Choudhury, B. Nestler
Ternary eutectics develop a rich variety of microstructures depending on the solidification conditions. This article describes a new procedure to analyze the three-phase arrangement in metallographic sections following solidification; this method provides a clear definition of both the interphase spacing and the degree of ordering. Distance and angle between the phase areas are calculated after de...... hiện toàn bộ
The PC-GTAW of Ti–6Al–4V Thin Sheets and Its Effects on Mechanical and Microstructural Properties
Springer Science and Business Media LLC - Tập 8 - Trang 871-879 - 2019
Amirkeyvan Rahimi, Morteza Shamanian
In this study, annealed Ti–6Al–4V alloy sheets with a thickness of 1 mm and with a butt-joint design were welded using gas tungsten arc welding without using filler metal. The aim of this study was to compare the specimens of the welding process with different current ratios (Ib/Ip) to find sample with high tensile strength and toughness. The welded specimens with optimal pulsed current ratios (Ib...... hiện toàn bộ
