The Revelation of Corrosion Origins in 3D-Printed Stainless Steel

Amidst the world of stainless steel manufacturing, a new panorama emerges. Slags, those byproducts of deoxidizers, have long been known to appear in traditional 316L stainless steel production. Ordinarily, these materials form a solid phase in the liquid metal, ready to be purged post-production. However, the landscape shifts in the realm of laser powder bed fusion (LPBF) 3D printing. Researchers at LLNL unveil a unique discovery—slags, which are staples of standard manufacturing, linger on the surface in the LPBF process, instigating pitting corrosion. “Pitting corrosion, enigmatic and capricious, has perplexed many. Yet, our team has unearthed the material attributes that

The Innovation of Non-Flammable Electrolytes in Lithium-Metal Batteries

Research and Development of a Groundbreaking Solution Improving the stability of high-voltage chloride-based solid electrolytes (Li3MCl6) has been a long-standing challenge for researchers in the field. A recent breakthrough by a collaborative team has proposed a revolutionary design principle – a chloride-based solid electrolyte (Li3MCl5F) incorporating fluorine (F), known for its robust chemical bonding capabilities. By leveraging the supercomputing resources at LLNL for precise calculations and conducting experimental validations at KIST, this innovative approach marks a turning point in battery technology. The strategic alliance adopted a cost-effective and time-efficient method, where computational simulations guided the initial material design, followed by
