In ferritic stainless steel (FSS), undesirable surface defects of ridging appear during deep drawing. The formation of these defects is attributed to the inhomogeneous distribution of orientations of individual grains. In the present work, a new electron backscattered diffraction R(α)-value map was introduced, and the dependence of the tensile directions on the formation of ridging in an FSS sh...

The technique of strengthening steel structures with Carbon Fibre Reinforced Polymer (CFRP) has attracted growing attention in research field and in practice and its environmental durability is of high importance. This paper describes an investigation on the bond characteristics between high modulus CFRP sheet and steel plates under elevated temperature exposures. Tensile tests were carried out...

Radio Frequency IDentification (RFID) tag is a promising device for the management of products at a very low cost. Huge number of such low-cost sensors can be installed to the structure beforehand, after a disaster we can access to these sensors wirelessly and very easily. In this system, a printed sheet is applied to a part of structure in which crack will occur. Copper wire is connected to th...

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

The core loss of electrical steel is defined as the dissipation of electrical energy in the form of heat during magnetization by an alternating current. Many efforts have been made to reduce the core loss. Numerous parameters, including the chemical composition and the metallurgical technology, influence the properties of the steel. Electrical steel sheets are mainly produced from Fe-Si-C alloy...

In collaboration with Ametek and Commonwealth Scientific and Industrial Research Organization (CSIRO), Oak Ridge National Laboratory has evaluated three different methods for converting titanium hydride-dehydride (HDH) powder into thin gauge titanium sheet from a roll-compacted preform. Methodologies include: sintering, followed by cold rolling and annealing; direct hot rolling of the rollcompa...
