- A team of material scientists at Pohang University of Science and Technology in South Korea announced what they're calling one of the biggest steel breakthroughs of the last few decades: an altogether new type of flexible, ultra-strong, lightweight steel.
- This new metal has a strength-to-weight ratio that matches even our best titanium alloys, but at one tenth the cost, and can be created on a small scale with machinery already used to make automotive-grade steel.
- Before the new material can be mass-produced, researchers must confront a tricky production issue: currently, steelmakers use a silicate layer to cover and protect mass-produced steel from oxidation with the air and contamination from the foundry. This silicate can't be used for Kim's steel because it has a tendency to react with the cooling aluminum, compromising the final product.
