In literature the influence of curvature on formability has been reported. This paper shows results for four materials when an FLC is measured with increasing curvature. It shows the FLC increases for sharper curvature most notably with 20 [mm] tool diameter. The increase is negligible on the left hand side, moderate on the right hand side and large on the plane strain axis. It is thought that ...

In search for new manufacturing process, Single Point Incremental Forming (SPIF) emerged to be one of the useful processes for forming complicated shapes. This is a flexible forming process which eliminates the die, punch and errors due to them. It is widely used for batch production of different shapes which has applications in diverse fields like automobile, aerospace, medical industry, packa...

Because of the need for weight reduction in transport industry, in order to save energy as well as to reduce CO2-emission, the use of light weight aluminium sheet is taken increasingly into consideration [1]. But although aluminium is lighter than steel, the formability is less, hence press operations are often more critical. Alloys used are typically 5xxx alloys for inner panels because of the...

The formation of the icosahedral phase (I-phase) as a secondary solidification phase in Mg-Zn-Y and Mg-Zn-Al base systems provides useful advantages in designing high performance wrought magnesium alloys. The strengthening in two-phase composites (I-phase + α-Mg) can be explained by dispersion hardening due to the presence of I-phase particles and by the strong bonding property at the I-phase/m...

The locking compression plate fixation treatment for the unstable sacral fractures is simple and effective, with less trauma and complications. Some locking compression plate parts have been made of high-strength Plate manufactured by hot stamping process since the demand for lightweight biomedical materials. Finite Element (FE) method of One-Step inverse forming based on deformation theory is ...

In recent years many different ways have been investigated by steel producers to increase ductility, impact strength and formability of steels. More important ways are steels with very low amounts of inclusion, small size inclusions and modified inclusions. In this study, experiments have been performed on the API-X42 steel produced by the electric arc furnace in Mobarekeh Steel Co. After the p...
