A new study has found that the element Lead (Pb) when introduced to high pressures, similar to the core of Earth, undergoes hardening and turns from soft to extremely strong. The combination of high pressure, pressure-induced hardening and polymorphism results in an average inferred flow stress of around 3.8 GPa at high pressure, an approximately 250-fold increase.
