Qianxi (Emily) He is a Faculty Lecturer at McGill University, specializing in advanced materials processing and machining technologies. Her research focuses on optimizing cutting tool performance through innovative coating strategies and understanding wear mechanisms in extreme machining conditions. She has contributed to studies involving PVD coatings (e.g., AlCrN, AlTiN), tribology, and the machining of challenging materials like titanium alloys and super duplex stainless steel. Her work frequently addresses practical applications such as improving tool longevity, reducing machining-induced defects, and enhancing surface integrity. Key topics include thermal stability of coatings, stress corrosion cracking mitigation, and the impact of heat treatment on material properties. Dr. He’s publications highlight a strong emphasis on empirical validation through controlled experiments, often comparing different coating compositions or machining parameters. Her research is grounded in both theoretical material science principles and industrial manufacturing challenges. Notable contributions include studies on SiAlON ceramic inserts for high-speed milling, novel edge design approaches to delay tool wear, and the role of austempering in steel microstructure evolution.
