What Are Precipitates in Metallurgy

Precipitation is when a solid (a precipitate) is created in a solution during a chemical reaction or by diffusion. … The metallurgy process of alloy strengthening uses the process of precipitation from solid solutions.

What are precipitates in materials?

More generally, precipitates are small impurity regions that form in a material when it is no longer able to dissolve the impurity.

What are precipitates in alloy?

The particles, which are called precipitates, impede dislocation motion through the alloy. … Not every alloy can be precipitation strengthened. Alloys that can be precipitation strengthened include Al-Cu, Al-Mg-Si, Cu-Be, and 17-8 PH steel. The figure shows precipitates in a Al-Cu alloy.
