On the Optimisation of Superplastic Free Forming Test of an AZ31 Magnesium Alloy Sheet

This paper presents a comparison between a number of different failure prediction methods forsuperplastic forming processes. Attention is limited here to superplastic forming of Ti-6Al-4V at 927C. Thefailure prediction methods considered include the flow localisation factor approach, forming limit curvesbased on void growth models, such as the Rice and Tracey model and the Cocks and...

Towards Superplastic Forming of Az31 Magnesium Alloy with Controlled Microstructure

A recent study on post-superplastic forming properties has shown that heating time prior to testing has a major effect on the post-forming properties of superplastically-formed AZ31 Magnesium alloy sheets. To this point, there has been very little examination into the effects of pre-heating or annealing on superplastic forming. In this work, these effects are examined using AZ31 Mg alloy sample...

The Effects of Forming Parameters on the Single Point Incremental Forming of 1050 Aluminum Alloy Sheet

The single point incremental forming (SPIF) is one of the dieless forming processes which is widely used in the sheet metal forming. The correct selection of the SPIF parameters influences the formability and quality of the product. In the present study, the Gurson-Tvergaard Needleman (GTN) damage model was used for the fracture prediction in the numerical simulation of the SPIF process of alum...

Superplastic Forming of AZ31 Magnesium Alloy Sheet into a Rectangular Pan

Superplastic behaviour of Mg-alloy AZ31 was investigated to clarify the possibility of its use for superplastic forming (SPF) and to accurately evaluate material characteristics under a biaxial stress by utilizing a multi-dome test. The material characteristics were evaluated under three different superplastic temperatures, 643, 673, and 703 K in order to determine the most suitable superplasti...

Numerical and experimental study of AZ 31 - O magnesium alloy warm sheet forming

Lightweight materials have been studied widely at present. Because weight reduction while maintaining functional requirements is one of the major goals in industries in order to save materials, energy and costs, etc. As the lightest structural alloys, magnesium alloys offer great potential to displace the most commonly used materials, because its density is about 2/3 of aluminum and 1/4 of stee...
