Abstract
Forming temperature is one of the basic parameters of warm sheet metal forming. The elevated temperature reduces the deformation resistance and affects the susceptibility of the material to forming. In the investigations which results are presented in the article, an attempt was made to modify the forming process the bearing housing of fan engine. The housing is made of hardly-deformable stainless steel AMS5604. This material has low formability margin, and therefore, it is necessary to use non-conventional two-stage forming process: forming of preliminary shape in rubber-pad forming process and calibration of final shape at elevated temperature using a metallic dies. The paper presents also the results of metallographic analysis and chemical composition of the sheet after forming.
