Quenching - Wikipedia

Moreover, it appears that, at least in Europe, 'quenching and tempering separately do not seem to have become common until the 15th century'; it is therefore helpful to distinguish between 'full quenching' of steel, where the quenching is so rapid that only martensite forms, and 'slack quenching', where the quenching is slower or interrupted, which also allows pearlite to form and results in a ....
