Question

Quizplus · Accepted Answer

Tempering is a careful heat treatment process that involves heating the metal to a specific temperature and then cooling it quickly to harden it. However, the metal may become too brittle and prone to cracking. To prevent this, the metal is then heated again to a lower temperature to reduce the brittleness while still retaining its strength. This process provides the proper combination of strength without too much brittleness. Core hardening is a different heat treatment process that involves hardening only the interior of a metal component, while fire polishing refers to a finishing process for glassware, and blast furnace and direct reduction are methods used in iron and steel production.
