Differences Between Normalized and Annealed 4130 Steel ...

Normalizing is a similar process to annealing except that the metal is heated to a higher temperature and cooled slowly over hours or even days. This slow cooling removes almost all the internal stress within 4130 steel and creates a ductile material with a higher tensile strength compared to annealed steel at 106,000 psi. The steel has the ...

What is Database Normalization? - SearchSQLServer

Database normalization is the process of organizing data into tables in such a way that the results of using the database are always unambiguous and as intended. Such normalization is intrinsic to relational database theory. It may have the effect of duplicating data within the database and often results in the creation of additional tables.

Annealing (metallurgy) - Wikipedia

The solubility of carbon in iron is higher in the austenite phase. Normalizing heat treatment produces a more uniform carbide size which aids further heat treatment operations and results in a more consistent final product. The process of normalizing is explained in following.
