Hardness Test | GRHardnessTester.comMost metals are composed of tiny crystals which determines the metal’s properties such as it’s hardness or ductility.  In many high-tech metals, you can boost it’s hardness by creating an alloy with many nanocrystals.  The hardness can be lost, however, when the metal is stressed or under high temperatures because the crystals merge.  So, Heather Murdoch created a mathematical model to help scientists predict which allows will be stable without having to create them and try them out first.  Murdoch and her team tested tungsten, which is one of the strongest metals, with her model and it proved to be correct.
