· JVASP-41056· HfAlRh2

HfAlRh2 is a ternary intermetallic compound combining hafnium, aluminum, and rhodium—a research-phase material belonging to the family of refractory metal intermetallics. While not yet established in production engineering, this material family is pursued for extreme-temperature applications where conventional superalloys reach their limits, with potential relevance to aerospace propulsion, nuclear systems, and high-temperature structural components where density, stiffness, and thermal stability are balanced design constraints.
