【 摘 要 】

The continuous demand for light weight and cost reductions, in the aerospace industry lead to development of different metal forming techniques with higher formability. In this study the deforming behaviour of face-centered-cubic Structured Aluminum Alloy and Hexagonal Closed Packed Commercially Pure Titanium under different lubrication condition is analyzed. Due to different types of bonding among atoms in face-centered-cubic Structure and Hexagonal Closed Packed structure exists, this leads to differences in capability of forming to a required shape. As the light weight components are desired for aircrafts, the maximum formability is desirable to achieve a uniform thickness of formed component without reduction of thickness. Generally, formability depends upon forming conditions, crystal structure as well as on coefficient of hardening at room temperature. The parameters which influence the formability are analyzed and optimized. It is evaluated that high temperature deforming improves formability for both materials. It is also evaluated that the tribological conditions varied due presence of lubricant, Hence influence the forming behaviour and formability.
