I was reading "Science News" earlier today. There is an article about how "lead gets stronger than steel" when subjected to massive pressure, equal to what is at the earth's core. The full paper can be found at: " Extreme hardening of Pb at high pressure and strain rate. Physical Review Letters. Vol. 123, November 15, 2019, p. 205701. doi: 10.1103/PhysRevLett.123.205701.
Emmily Conver wrote the short synopsis that I read.. It interested me because I recall a discussion we had about lead and pressures about a year ago. Any this has been FYI enjoy.
