Used for aluminum, some stainless steels, and nickel alloys. A second phase precipitates from solid solution during a controlled low‑temperature heat treatment, blocking dislocations. Unlike steel, these alloys become harder not by quenching but by aging after a solution treatment.

Metallurgists categorize materials into two main "families" based on their iron content: Metallurgy for the Non-Metallurgist | Technical Books Used for aluminum, some stainless steels, and nickel alloys
Metallurgy is the science and engineering of metals: how they are extracted, processed, alloyed, shaped, and how their structure controls properties and performance. Used for aluminum
