"Revolutionary Treatment Enhances Steel Alloys with Unmatched Strength and Flexibility"

Researchers at Purdue University and Sandia National Laboratories have developed a new treatment for T-91 steel alloy, resulting in a stronger and more ductile version called G-T91. The treatment creates ultra-fine metal grains in the outermost layer of the steel, conferring super-plasticity. This discovery could have significant implications for applications such as car axles and suspension cables. However, the exact mechanism behind this phenomenon remains unclear, and further research is needed to understand the behavior of the grain boundaries.
