A press formed product is disclosed. A method for manufacturing the press formed product is a method for manufacturing the press formed product including applying press processing including stretch flange forming to a single metal sheet of one sheet material after performing shearing processing of the metal sheet to manufacture the press formed product. When a region where a stretch flange crack is estimated to be likely to occur when the single metal sheet is press formed by the press processing is set as a stretch flange crack region, the press processing is applied after heating and cooling the end surface of the metal sheet positioned in the stretch flange crack region and at least the end surface in the end surface and the vicinity thereof in the single metal sheet after the shearing processing.

An apparatus for forming an aluminum plate is provided. The apparatus includes an upper die that has a bottom surface that corresponds to a top shape of a product shape to be formed and descends by a press to press the aluminum plate. The apparatus also includes a lower die that has an upper surface that corresponds to a bottom shape of the product shape and an electrode unit that is inserted into the lower die and is exposed on the upper surface of the lower die to apply a current to a bent portion of the product shape.

The present disclosure provides methods for preparing an extruded product from a solid billet. The methods can include providing an as-cast billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the as-cast billet to plasticize the as-cast billet; and extruding the plasticized as-cast billet with an extrusion die to form an extruded product. Methods for preparing extruded products from billets can also include: providing a billet for extrusion; while maintaining a majority of the billet below 100° C., applying a simultaneous rotational shear and axial extrusion force to one end of the billet to plasticize the one end of the billet; and extruding the plasticized one end of the billet with an extrusion die to form an extruded product. Methods for preparing an extruded product from a billet can also include providing a billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the billet to plasticize the billet; extruding the plasticized billet with an extrusion die to form an extruded product; and artificially aging the extruded product for less than the ASTM recommended amount of time.
