    Abstract: A press forming method of press forming a formed part including a top portion having a concave outer edge with a part of the outer edge being concave inwards and a flange portion subjected to bending forming along the concave outer edge of the top portion includes: a first forming step of forming a preformed shape part including, in a part where the flange portion is formed in a blank material, a vertical wall portion that becomes a part of the flange portion and a mountain shaped portion that is bent outwards from the vertical wall portion and is convex towards the top portion; and a second forming step of forming the flange portion by performing bending forming on a part including the mountain shaped portion of the preformed shape part formed at the first forming step along a bending line that is a boundary from the vertical wall portion.

    Abstract: A method of producing a shaped aluminum alloy panel, preferably for aerospace or automotive applications, from 5000-series alloy sheet. The method includes: providing a sheet made of 5000-series alloy having a thickness of about 0.05 to 10 mm and a length in the longest dimension of at least 800 mm; and stretch forming the sheet at a forming temperature between −100° C. and −25° C., to obtain a shaped aluminum alloy panel. A shaped article formed by the above method is also provided.
