How Does Precipitation Hardening Work?

Precipitation hardening (also known as age hardening) is a heat treatment process used to increase the strength of metals and alloys. This process is commonly used for metals such as aluminium, copper, and titanium – but how does it work? Let’s take a closer look at the science of precipitation hardening.

What is Precipitation Hardening?

Precipitation hardening is a metal or alloy strengthening process that works by introducing small amounts of other elements into the metal or alloy, allowing it to form precipitates which provide further strength. It involves heating the metal or alloy to an elevated temperature, holding it there for several hours while allowing the particles to form, and then cooling it in order to ensure that those particles remain in place. As time passes, these particles will grow larger and form even more intricate structures – this is why this process is also referred to as age hardening.

Benefits of Age Hardening

Age hardening provides numerous benefits compared to other common strengthening processes like cold working and solid solution hardening. For one thing, age hardening allows for increased strength at lower temperatures than other processes – meaning that any parts that are subjected to low-temperature environments can still benefit from increased strength. Furthermore, age-hardened parts tend to be better able to resist fatigue damage due to their increased hardness (which helps reduce stress concentrations). Finally, age-hardened parts can also be machined faster than cold-worked parts due to their improved wear resistance.
