Two step–ageing of 7xxx series alloys with an intermediate warm-forming step

Journal of Materials Research and Technology, 2021
Two-step ageing of 7xxx series alloys can reduce ageing time while obtaining similar mechanical properties as a longer isothermal heat treatment. In this paper, an intermediate deep-drawing step at 120–160 °C is introduced to produce elongated cup–shaped

Robot-Assisted Cold and Warm Incremental Sheet Forming of Aluminum Alloy 6061: A Comparative Study

Metals, 2023
Incremental sheet forming (ISF) requires no or partial dies for sheet metal fabrication and is widely used for small batch production. In this process, necking is either suppressed or delayed due to the localized nature of tool–sheet contact; hence, more

Nonisothermal Warm Deep Drawing Behavior of Automotive Grade Aluminum Alloy Sheets

IOP Conference Series: Materials Science and Engineering, 2021
Abstract In this work, thermomechanical FE modeling of nonisothermal warm deep drawing of automotive grade AA5754 and AA6082 aluminum alloy sheets were performed. The deformable blanks were modeled using temperature dependent Cowper-Symonds constitutive equation along with Barlat-89 yield criterion.

Finite element simulation of ironing process under warm conditions

Journal of Materials Research and Technology, 2014
Metal forming is one of the most important steps in manufacturing of a large variety of products. Ironing in deep drawing is done by adjusting the clearance between the punch and the die and allow the material flow over the punch.

COMPARISON OF CONVENTIONAL DRAWING, INVERTED DRAWING AND WARM FORMING PROCESSES FOR DEEP DRAWING OF ALUMINIUM CUPS

International Journal of Mechanical and Industrial Engineering, 2014
Cup drawing is one of the important operations in sheet metal forming. Manufacturing of the aluminium base cup involves several stages such as blanking, first drawing, second drawing, taper formation and trimming. This increases the process time. An attempt has therefore, been made to develop a comprehensive, rigorous, yet easily-workable method of ...
