Refraktory metalů, such as tungstein, molybdenum, and tantalum, are known for their high melting points and exceptional tillth at elevated temperature. However, maintaining their microstructure stability under extreme conditions establions a establile. Grain Boundary Engineering (GBE) has emerged as a promising accter tho enhance thee stability and perfectance of these materials.
