What is it about?
We investigated the relationships between processing and forming properties in 90/10 brass, one of the most common copper alloys. We showed that, in spite of the different processing schedules resulting in different final microstructures, the forming proprieties didn't change significantly. We postulate that crystallographic texture, that is, the non random distribution of grain orientations in the polycrystal, is able to overcome other factors which could lead to different formabilities.

Why is it important?
Understanding the forming properties, that is how much and how easy a metal can be deformed, is important to optimize processing in the alloys.
Perspectives
This work was part of Mr. Almeida's master in science thesis at the Escola Politecnica da USP. It was a pleasure working with him, and, in particular, I learned a lot about copper alloy metallurgy in this project.
