Figure 1: Typical properties expected of an ideal metal for present-day industrial applications include high strength, good ductility, excellent corrosion resistance, high fracture toughness, and the ability to be used at elevated temperatures. Since such a metal currently does not exist, let us call it utopium (not utopia, since the names of most metals end with ….um, e.g., aluminum, magnesium, titanium, uranium).
