The development of W-Cr-Al alloys by spark plasma sintering and their oxidation behavior

Key Points

• The oxidation behavior of W-Cr-Al alloys demonstrates significant improvements when processed through spark plasma sintering, indicating durability.
• Key evidence reveals that these alloys result in a lower weight loss percentage during oxidation tests at elevated temperatures over a specified timeframe.
• Assessment using spark plasma sintering revealed refined microstructure features at the nanoscale, contributing to improved oxidation resistance.
• The findings highlight the potential of W-Cr-Al alloys for high-temperature applications, but further studies are needed to evaluate long-term performance.
