Project Details
Description
This project is a continuation of work carried out within CORE 814 & 1138 – Gas Furnace Characterisation on the hydrogen pickup and alpha case characterisation on Ti alloy parts submitted to heat treatment in a gas fired furnace.
For this year’s CORD project, we want to put the emphasis on parts with various finishes (ground, cast, machined) and different coatings (ATP40 & Prince Minerals coating). Some of the cast samples will also be submitted to press trials to evaluate the coating resistance/structure after one pass similarly to the cogging process.
Post heating analysis of the parts will be used to determine the amount of hydrogen and the oxidation layer in the samples. This should help us to improve our knowledge on the hydrogen pickup phenomenon, alpha case formation on Ti64 alloy materials and the usefulness of coating.
This project will be mainly funded using some remaining TIMET votes from CORE 20/21 programme.
The AFRC’s proposed approach to this project is described below in a series of 2 individual work packages.
