The benefits of precipitation hardening

Heat treatment is something many people need to think about when they choose metals. However, it can be difficult sometimes to get a grip of some of the terms. We would love to help. As a leading stockist of various metals and products, we have a lot of experience here. In fact we offer many products with specific types of treatment. This includes options like nickel alloy round bar in alloy 80A.

Many terms for the same thing

One term in particular that can confuse some people is precipitation hardening. The issue here is that some people also refer to it as age or particle hardening or simply ageing. However, all of these mean the same thing and the process is always the same.

How does it work?

What happens here is there is an extra solution annealing process once the forging or rolling finishes. This involves holding the alloy at a high temperature for a period of time. It could be as high as 1,000 degrees Celsius for several hours. However, it is also possible to adapt the temperature and length of time. In some cases a single alloy may have several periods at different temperatures to produce a range of strength levels.

Following the period or periods of heating, the metal requires quenching. This could cool it quickly or slowly depending on the needs.

Why use this type of hardening?

What this process does is change the solubility of some elements within the alloy. As a result the small particles of precipitates spread throughout the microstructure. They can therefore support grain boundaries. Ultimately this means you have a much stronger alloy. It can have especially good yield strength.

With this kind of hardening it is much easier to create the optimum alloy. It is a much better option than relying on the strength purely from the alloying process.

The higher strength alloys are great for a huge array of applications where it is vital that the metals are stronger than usual.
