Hot extrusion of α and α/β-brass alloys
-
Björn Reetz
Abstract
The investigations aim at the control of the formability and the strength of hot extruded brass alloys through choosing the appropriate hot extrusion parameters. Different α-brass and α/β-brass alloys, namely CuZn10, CuZn20, CuZn37 and CuZn40Pb2, were hot extruded and subsequently investigated by means of microscopy, X-ray diffraction and mechanical testing.
The investigations show that the strength and formability of the extrudates are strongly affected by the hot extrusion parameters which determine the grain sizes and the textures of the extrudates. Additionally in the cases of CuZn37 and CuZn40Pb2, multiple phase transformations arise during the hot extrusion process and affect the resulting properties. The bcc β-phase content especially depends on the extrusion temperature, deformation degree and deformation rate.
