High Explosive Anti-tank Warhead
High explosive anti-tank (HEAT) warheads are made of an explosive shaped charge that uses the Munroe effect to create a very high-velocity partial stream of metal in a state of superplasticity that can punch through solid armor.
Contrary to a widespread misconception perpetuated by the acronym, HEAT rounds do not depend in any way on thermal phenomena for their effectiveness. In particular, the shaped charge jets do not "melt their way" through armor, only reaching 500-600°C, and instead rely on extreme pressure to force a hole through the armor.

Famous quotes containing the words high and/or explosive:
“It is not their bones or hide or tallow that I love most. It is the living spirit of the tree, not its spirit of turpentine, with which I sympathize, and which heals my cuts. It is as immortal as I am, and perchance will go to as high a heaven, there to tower above me still.”
—Henry David Thoreau (1817–1862)
“Anyone who has obeyed nature by transmitting a piece of gossip experiences the explosive relief that accompanies the satisfying of a primary need.”
—Primo Levi (1919–1987)
