Abstract The relationship between microstructure features and mechanical properties plays an important role in the design of materials improvement properties. Hole expansion capacity a fundamental defining formability metal sheets. Due to complexity experimental procedure testing hole capacity, where many influencing factors contribute resulting values, this relation is not yet fully understood...

Abstract Warm forming has been shown to be an effective way increase the formability of various aluminum sheet alloys. If applied precipitation hardenable alloys, aging and/or coarsening may occur during heating processes. As such, there is a potential leverage warm process artificially age In this study, characteristics pre-aged Al-Mg-Si-Cu alloy (designated AA6013-PA and comprising 4 h, 100 °...

modern vehicle bodies make intensive use of high strength steel grades to meet the contradicting demand of lighter weight and simultaneously better mechanical performance. for many steel grades microalloying by niobium is the key to achieve their characteristic property profile. in hsla steels niobium enhances the strength primarily by grain refinement. in interstitial free high strength steels...
