Wallis and Futuna 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 less brittle product. Vatican Sao Tome and Principe Saudi Arabia Argentina The distortion of the workpiece can be corrected by straightening, but only within the limits of the plasticity of the workpiece. Cook Islands The process of Quench and Tempering is important because it improves the mechanical properties, hardness and toughness of the alloy material.
