MAX phases, a new type of ceramics with unique properties of metal and ceramic: lightweight, readily machinable, good heat and electricity conductivity, elastically stiffness, resistant to chemical attack, thermal shock, damage tolerant, and sometimes fatigue, creep, and oxidation resistant. They have wide potential applications in future industry. This book is involved in synthesis, microstructural characterization and mechanical property measurements of Ti3AlxSn(1-x)C2 MAX phases. It offers different parameters about those MAX phases, from material preparation to microstructural characterization, from crystalline properties to macro mechanical properties and the relationship between the microstructures and properties. It is a great helpful book for the materials researchers either in science or engineering.
