Improvement of material flow in tube hydroforming by advanced sealing methods

Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, 2023
In this paper, two advanced sealing methods are proposed to enhance the formability of aluminium alloys in the tube hydroforming process. These methods are aimed at omitting friction force at the contact area between the tube and the die in the feed ...

Tribological Characteristics of Dual-Pressure Tube Hydroforming

Defect and Diffusion Forum, 2022
Dual-pressure tube hydroforming (THF) is a tube hydroforming process variant whereby deformation of the tubular specimen is achieved by exerting fluid pressure on both the inside and outside surfaces of the tube.

Magnesium Tube Hydroforming

AIP Conference Proceedings, 2007
Magnesium alloys can be considered as alternative materials towards achieving light weight structures with high material stiffness. The formability of two magnesium alloys, viz. AZ31 and ZM21 has been experimentally tested using the IHP forming process.

Tube Formability Assessment for Tube Hydroforming

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">Determination of forming limit of tubes can be difficult when it involves many process related variables and the use of costly hydroforming equipment. Therefore, the industry currently relies on sheet or tube longitudinal properties to estimate tube hydroformability.

Effect of Die Velocity on Tube Deformation Mechanics During Low Pressure Tube Hydroforming Process Sequence Variation

Volume 2A: Advanced Manufacturing, 2021
Tube hydroforming is one of the successful manufacturing processes to create a variety of shapes using fluid pressure. The process fills the tube with fluid and pressurizes it to deform in various cross-sections.

Magnesium tube hydroforming

Materialwissenschaft und Werkstofftechnik, 2008
AbstractMagnesium alloys reveal a good strength‐to‐weight ratio in the family of lightweight metals and gains potential to provide up to 30 % mass savings compared to aluminium and up to 75 % compared to steel. The use of sheet magnesium alloys for auto body applications is however limited due to the relatively low formability at room temperature ...
