reality check - Is there a way to make a metal sword

2019-3-18 · OK, I think melting point is the wrong thing to think about here. The first thing is specific heat capacity, which tells us how much heat energy is needed to raise the temperature of 1kg of a substance by 1 Kelvin.. So, a metal with high specific heat capacity can absorb more energy without ill effects.

The origin of the asselage of ultra-high pressure (UHP), super-reduced (SuR) and several crustally derived phases in ophiolitic chromitites is still hotly debated. In this paper, we report, for the first time, this asselage of phases in ophiolitic chromitites of the Caribbean. We studied the Mercedita chromitite deposit in the eastern Cuban ophiolitic complexes.
