| Abstract Scope |
Induction Bending of high Chromium Alloys such as Duplex and Austenitic Steels combines forming and Solution Treatment processes.
The transition Zones from the parent material to the bend have always been a point of concern to the manufacturers and end users. The HAZ, if not corrently controlled, can exhibit unwanted properties such as a drop in corrosion resistance and toughness due to grain boundary Precipitates and in extreme situations the formation of deleterious phases.To eliminate this possibility, Industry Specifiactions often call for mandatory post bend Solution Treatment which adds considerable additional cost, energy use and physical distortion of the bend.In this study I intend to give the reader an understanding of the Induction Bending process, the causes of deleterious micro-structures in High Chromium Alloys and the manufacturing methods used to prevent these occuring without relying on Post Bend Heat Treatment. |
