Abstract

Recently, formable metal sheets with a high strength-to-weight ratio have been developed especially to conserve energy and resources. For this purpose, two conditions are necessary: the strengthening of the sheet metal and improvement of the press-formability, which are difficult to obtain together. In the present study, the conditions necessary for this are examined using solid-solution type aluminum alloy sheets. Moreover, a new measure to assess press-formability is proposed in terms of the strain-hardening capability and plastic-anisotropy based on fracture behavior of sheet metals.
