Heat Treatment as an Alternative to Brass Warping

Article Preview

Abstract:

This paper proposes the reduction of warping after the machining of alloys of brass with lead. For this purpose the brass alloys were submitted to heat treatment and analyzed before and after the machining process. Elongation and dimensional variation, microstructure and chemical microanalysis of the samples were assessed. It was found that warping may be related to the chemical composition of the alloy, added to the rolling process used to obtain the material to be machined. The results showed that heat treatment before the machining process eliminates the warping seen in the workpieces.
