The metal looks as though it goes molten briefly just at the beginning of the strike! And that is a lot of energy being converted to heat - but I guess it has to convert to molten - the stop is so abrupt!
That is exactly what happens.
The depleted uranium sabot round from the 120 mm M1 Abrams main gun strikes with sufficient kinetic energy to melt armor plate and cause the sprewel to go into the tank, spraying everything inside with molten metal.
