A New Method for Preparing Titanium Aluminium Alloy Powder

open access: yesMetals, 2023
Due to TiAl alloys’ excellent properties, TiAl alloys have received widespread attention from researchers. However, the high energy consumption and lengthy process of traditional preparation methods have always limited the large-scale application of TiAl

Elimination of misrun and gas hole defects of investment casting TiAl alloy turbocharger based on numerical simulation and experimental study [PDF]

open access: yesChina Foundry, 2020
Casting technology of thin-wall TiAl alloy turbochargers was studied by investment casting and numerical simulation. Misruns and gas holes were the main defects observed in preliminary work due to the poor fluidity of alloy, and to gas entrapment.

Combustion of TiAl alloy in nitrogen [PDF]

open access: yesCombustion, Explosion, and Shock Waves, 2015
It has been shown that Ti–Al–N ternary compounds, belonging to MAX phases (ceramic materials that can be processed as metals) can be produced by combustion of a granular powder of T65Yu35 (TiAl) alloy in nitrogen flow at a pressure close to atmospheric pressure. Combustion is accompanied by transfer of part of the aluminum through the gas phase.

Non-isothermal oxidation characteristic of titanium-aluminium intermetallic alloys

open access: yesCailiao gongcheng
The non-isothermal oxidation behaviors of TiAl and Ti3Al alloys at 1450-1570 ℃ in a pure oxygen atmosphere were studied by using TGA/DSC simultaneous thermal analysis, SEM and EPMA characterizations and theoretical calculation.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

open access: yesAdvanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial

Microstructure and shear property of high-temperature brazing of TiAl alloy and 316L stainless steel with a Ni-based amorphous filler

open access: yesFrontiers in Materials, 2022
High-quality joining of TiAl alloy to stainless steel is of great significance to the aerospace field. However, the hybrid structure of TiAl and 316L always suffers from insufficient strength when serving at elevated temperatures.

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.
