Lead Becomes Stronger Than Steel Under Extreme Pressures
Lead performs under pressure. Under normal conditions, the metal is relatively soft, easily scratched with a fingernail. But when compressed under extreme pressures, lead becomes hard and strong — even stronger than steel, scientists report November 11 in Physical Review Letters. Researchers rapidly compressed a lead sample by blasting it with lasers at the National Ignition Facility. (Science News)

Sarah T. Stewart, a planetary physicist at UC Davis: “We can reach the core pressures in the Earth, but I can’t reach the range of giant impacts or the center of Jupiter in my lab. But the Sandia Z machine, which is a big capacitor that launches metal plates using a magnetic force, can reach 40 kilometers per second. And with the National Ignition Facility laser at Lawrence Livermore National Lab, we can reach the pressures at the center of Jupiter.” (Nautilus)
