Solubility Charts

We’ve made some headway in MAT033, and we’ve moved beyond stress-strain diagrams, which was a pretty easy section for me as a Mech E major as most of it was review. We’ve moved back into unfamiliar territory with solubility charts.

In essence, these charts look at certain alloys at different temperature and then identify what phase it is in. With this information, you can tell the weight percent of each material in the alloy, whether it’s a liquid or solid, etc etc.

Here’s a picture of one of the solubility charts we need to be able to interpret.

It looks quite complicated, but in actuality, it’s not that bad. There also exists three-phase points, where it goes from one phase to two phases. Actually, now that I think about it, it’s pretty bad.
