Analysis

Smart steel that self-repairs cracks when heated could transform infrastructure maintenance. The material's ability to double strength after a simple thermal treatment offers a cost-effective way to extend the lifespan of bridges and buildings. If scalable, this technology could reduce inspection costs, prevent catastrophic failures, and improve public safety. The key questions now are long-term durability and production costs.
