What is the normalizing heat treatment?

Normalizing heat treatment is a process applied to ferrous materials. The objective of the normalizing heat treatment is to enhance the mechanical properties of the material by refining the microstructure. The ferrous metal is heated to the austenite phase, above the transformation range, and is subsequently cooled in still air at room temperature.

Heat Treatment of Steels Hardening, Tempering, & More

Carburization. It is a heat treatment process in which steel or iron is heated to a temperature, below the melting point, in the presence of a liquid, solid, or gaseous material which decomposes so as to release carbon when heated to the temperature used. The outer case or surface will have higher carbon content than the primary material.

Normalization (statistics) - Wikipedia

In another usage in statistics, normalization refers to the creation of shifted and scaled versions of statistics, where the intention is that these normalized values allow the comparison of corresponding normalized values for different datasets in a way that eliminates the effects of certain gross influences, as in an anomaly time series. Some types of normalization involve only a rescaling, to arrive at values …
