Structural Insights in the β to α Phase Transformation of the U–1 wt.%Ga–0.2 wt.%Fe AlloySpringer Science and Business Media LLC - Tập 3 - Trang 454-459 - 2014

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 $$ \beta \to
\alpha $$ transformation and the other is the precipitation of the U6Fe phase
from the iron dilute U(Ga)–Fe alloy. Furthermore, we determined the solubility
of i... hiện toàn bộ

This study studied the phase transformations occurring at different continuous
cooling rates in an air hardening steel used in the rock-crushing industry.
Samples of this steel were submitted for calorimetric testing using the
differential scanning calorimetry (DSC) technique. In the experimental run, the
samples were heated at the rate of 0.33 °C/s from 50 to 1050 °C and equilibrated
at this temp... hiện toàn bộ
Exploring the Effect of Ni as an Impurity on Fe-Rich Phases in Simulated Direct Chill Casting Al–Fe-Si AlloysSpringer Science and Business Media LLC - Tập 11 - Trang 724-735 - 2022

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 TreatmentSpringer Science and Business Media LLC - Tập 11 - Trang 569-579 - 2022

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
