Tempering is a heat treatment technique applied to ferrous alloys, such as steel or cast iron, to achieve greater toughness by decreasing the hardness of the alloy. The reduction in hardness is usually accompanied by an increase in ductility, thereby decreasing the brittleness of the metal. Tempering is usually performed after quenching, which is rapid cooling of the metal to put it in its hardest state. … WebTempering is one of the heat treatment processes in which the toughness of the material increases. In this heat-treating process, the material that are used are mostly related with … WebRetempering, the practice of adding water to mortar to restore workability, is considered good practice because it keeps mortar in the right condition for laying brick, block, and stone.
