This is where Shermanium’s mythical property emerges. Theoretically, Shermanium would be a shape-memory alloy (SMA). Like Nitinol (nickel-titanium), a Shermanium plate that has been dented by a kinetic penetrator could be heated with a simple oxy-acetylene torch. Upon reaching a specific transition temperature (say, 250°C), the crystal lattice would "remember" its original flat configuration, popping the dent out without hammering.
It may be a custom-named "element" in a game or a fictional universe, similar to how users name materials in games like Minecraft or Roblox . shermanium
While true Shermanium is a dream, the US Army Research Laboratory (ARL) is currently working on something remarkably close: , specifically a derivative of the alloy LM105 (zirconium-titanium-copper-nickel-beryllium). This is where Shermanium’s mythical property emerges
