Ultrasonic vibration‐assisted joining of multiform metallic glasses in varied environments

Abstract The evolution of joining technologies has profoundly propelled advancements across human civilization. Although modern joining processes have attained remarkable sophistication in conventional manufacturing, construction, and aerospace applications, their operational adaptability in special environments—including underwater, hyper‐corrosive, explosive, and cryogenic conditions—remains fundamentally constrained. This limitation underscores the critical demand for facile and robust joining methodologies tailored for specialized environments. Here, we present an innovative strategy using ultrasonic vibration to enable joining across diverse metallic glasses morphologies under these demanding conditions. Leveraging ultrasonic vibration‐induced plasticity and the unique activation mechanisms of metallic glasses, this approach demonstrates unprecedented compatibility with bulk, ribbon, and powder forms. Distinct engineered joint structures emerge across different materials, achieving mechanical strengths comparable to parent materials (1904 MPa compressive strength). This breakthrough establishes a transformative platform for offshore, polar, oil–gas, and space engineering applications and pioneers a universal design way for materials with programmable performance characteristics.
