At the Livermore National Laboratory. Lawrence in California (USA) conducted an experiment on the extreme compression of lead. It became one of a series of similar studies aimed at studying the transformation of the properties of various materials at ultrahigh pressures. For lead, for example, the main change was the increase in strength, which significantly surpassed that of steel.
During the experiment, American scientists used a system of many powerful lasers that continuously irradiated a lead target from all sides. Their total power provided a pressure of 400 gigapascals, which is close to the pressure at the center of the Earth. It turned out that lead compressed with such a force changes the atomic lattice and becomes extremely strong.
The strength of a material characterizes its ability to resist destruction. This indicator for supercompressed lead was 250 times higher than its eigenvalues under normal conditions and turned out to be 10 times higher than the parameters of steel.
Research on superstrength in its current format is fundamental and there is no talk of practical use. But this data will be useful in the future, when developing new types of armor, when designing the protection of space probes, which have to go to such unfavorable places as Venus or the surface of Jupiter, if it exists at all. Although if instead of it a layer of liquid metallic hydrogen is found, also under pressure, from which the mantle of this planet can be formed, this in itself will become an epoch-making discovery.
