In various thermomechanical applications, such as advanced gas turbines, thermal protection for space planes, and electric generation from oil and coal, high-performance materials are essential. Monolithic ceramics have limitations in toughness and reliability, leading to a focus on multi-phase materials as promising alternatives. These materials not only enhance thermomechanical performance but can also integrate multiple functions, including magnetic, electrical, and optical properties. However, several challenges remain, including microstructure complexity, processing difficulties, machining capabilities, and notably, cost issues. Fourteen scientists from nine leading research institutes across the Taiwan Strait provide insights and experimental evidence aimed at addressing these challenges. Their reports emphasize the principles of designing intricate microstructures and innovative processing techniques, while also demonstrating potential improvements in machining capabilities. Despite advancements, the critical issue of cost persists. With China's recent economic growth, there is a heightened demand for technological breakthroughs and value-added products. This underscores the importance of developing multi-phase materials with multifunctionality. As market growth continues, solutions to the cost problem are anticipated, particularly with the advent of mass production technologies.
