Study on Formability of TRIP Steel in Incremental Sheet Forming

Abstract:

The formability of a TRIP590 steel with 0.67mm thick in incremental sheet forming (ISF) was investigated. A variable angle cone, which opening diameter and generatrix radius are 100mm, and initial angle is 35 °, was formed until the specimen cracked. The depth at the intersection point of the actual wall thickness and theoretical wall thickness of the cone was measured, and the forming limit angle of the TRIP590 steel was got and about 66.5 °. Additionally, an arc groove and a cross arc groove were formed. Through measuring changes of the grids printed on the surface of the tested sheet, the forming limit diagram of the TRIP590 steel in ISF was obtained. The forming limit angle and diagram obtained can be used in designing the production process and numerical simulation of forming the TRIP steel.
