Metals, 2022 For currently used TiAl alloys, the impact resistance is a critically important property that determines their suitability for use, especially in settings when continuous use under harsh conditions is necessary. However, there are almost no examples of the investigation of the impact resistance of these alloys at realistic temperatures.

Site preference of transition-metal elements in L10-TiAl: A first-principles study [PDF]
arXiv, 2008 The site preference of 3d (Ti-Cu), 4d (Zr-Ag) and 5d (Hf-Au) transition-metal elements in L10 TiAl is studied using a combination of first-principles supercell calculations and the statistical mechanical Wagner-Schottky model. Our key finding is that both temperature and alloy stoichiometry can strongly affect the site occupancy behavior of ternary ...

Development of competitive high-entropy alloys using commodity powders [PDF]
arXiv, 2021 One of the main drawbacks of the powder metallurgy route for High-Entropy Alloys (HEAs) is the unavailability of fully pre-alloyed powders in the market. Using commodity powders (commercial Ni, Fe and Co base fully pre-alloyed powders, fully available in large quantities and at competitive prices) to produce HEAs presents a completely new and ...

Alloying elements partitioning in TiAl-Ru intermetallic alloys
Intermetallics, 1999 Abstract Ruthenium additions are of interest for increasing low-pH resistance as well as improving mechanical properties of TiAl. Two phase Ti-48 at% Al-0.5 at% Ru was investigated. The partitioning behaviour of alloying elements in this condition was investigated by atom-probe field-ion microscopy (AP-FIM).
