Important results from the project
The overarching goal was to establish Environmental Transmission Electron Microscope (E-TEM) as a viable tool for process development and material development addressing Technology Readiness Level (TRL) 1-3 Process developmen results: Investigating industrially significant processes like brazing of stainless steels with copper-nickel based filler alloys and lowering the sintering temperature with enhanced wettability cemented carbides Industrial product development cases: Brazed heat exchangers and hardmetal cutting tools
Expected long term effects
1. Use of E-TEM as a standard tool to investigate in-situ high temperature material behavior under various gaseous atmosphere and material interaction to derive mechanistic insights at atomic resolution. Henceforth, E-TEM is established as the reliable go to sophisticated instrument for direct observation of industrially critical processes 2. These live in-situ observation can be instrumental for designing more sustainable process and material development pivotal for green transition
Approach and implementation
Project was carried out according to the overall plan, with experimental work, partner collaboration and dissemination progressing well. Some activities were adjusted based on emerging results to focus on the most promising directions. The time plan was largely followed, with minor deviations due to technical challenges. External factors had limited impact. Unexpected findings influenced priorities positively. Collaboration between partners worked well and supported effective knowledge exchange.
