Tempering (metallurgy) - Wikipedia

Tempering can further decrease the hardness, increasing the ductility to a point more like annealed steel. Tempering is often used on carbon steels, producing much the same results. The process, called "normalize and temper", is used frequently on steels such as 1045 carbon steel, or most other steels containing 0.35 to 0.55% carbon.

Depending on whether a high hardness (“hardening”) or strength/toughness (“strengthening”) has to be achieved, the final process, the so-called tempering, is carried out at different temperatures. When a steel has to become very hard, it is only tempered at relatively low temperatures in the range of 200 °C to 400 °C, while it becomes tougher and high load capacity at higher

Heat Treatment of Steels & Metals - Bright Hub Engineering

Heat treatment of steels is the heating and cooling of metals to change their physical and mechanical properties, without letting it change its shape. Heat treatment could be said to be a method for strengthening materials but could also be used to alter some mechanical properties such as improving formability, machining, etc.

Tempered Martensite - Harry Bhadeshia

In high-carbon steels, the precipitation of excess carbon begins with the formation of a transition carbide, such as ε (Fe 2.4 C). ε-carbide can grow at temperatures as low as 50 o C. Indeed, most of the iron carbides can precipitate at low temperatures, well below those associated with the motion of substitutional solutes.

The steel is heated to over 1200 degrees Fahrenheit in order to create a solid solution of carbon and iron, a process that occurs because of chemical changes occurring in the steel alloy at such a high temperature. Once the steel has been austenized, it must then be quenched in order to bring about the next change in the metal.

how quenching hardens steel in metalworking

How Quenching Hardens Steel in Metalworking

Often used to harden steels, water quenching from a temperature above the austenitic temperature will result in carbon getting trapped inside the austenitic lath. This leads to the hard and brittle martensitic stage. Austenite refers to iron alloys with a gamma-iron base, and martensite is a hard type of steel crystalline structure.
