Important papers about tube hydroforming in the proceedings of the previous eight International Conference on Technology of Plasticity(ICTP) are reviewed.It is found that the pressure used in tube hydrobulge forming was low at early time,then,extra high pressure and axial feeding were applied in this technology;complex components with 2D and 3D axes can be formed by hydroforming;stainless steel,aluminum alloys and magnesium alloys are widely used in hydroforming these days;and warm hydroforming has become one important investigation now.
