In order to simplify production processes and to lower production cost of thicker coldrolled IF steel sheets for deep drawing applications, a new warm-rolled IF steel sheet was developed in our lab through hot-rolling in high-temperature ferrite range. In this paper, effect of processing parameters on properties, microstructures and precipitate morphology of warm-rolled IF steel sheets was investigated. It is found that firstly, good deep drawing properties and favorable textures were achieved as steels were warm-rolled in good lubricant condition. Secondly, most precipitates in steels were TiS, TiC, TiN and Ti4C2S2.

Interstitial Free Steel

Deep drawing is a sheet metal forming process in which deformation forces are oriented in the plane of the sheet, and the surface pressures in the tool are generally lower than the yield stress of the sheet material. The present work discusses the selection of sheet material suitable for a fuel tank by experimental evaluation of tensile properties of interstitial free steel and deep draw quality steel sheets of the same thickness of 0.8mm. The tensile specimens are laser cut from a blank with a known rolling direction and are tested for tensile properties and anisotropy. These tensile properties of the sheets are used in the material model in FE simulation of the deep draw process using HyperWorks. It is observed that an optimum blank holder force is necessary to remove the wrinkling defects. It is concluded that higher ductility and normal anisotropy are the key factors for higher thinning resistance in deep drawing and hence, interstitial free steel sheet qualifies as the better material for the fuel tank.

Interstitial-free (IF) sheet steels are largely used in automotive deep-drawing applications, as they offer both good formability and adequate strength for auto bodies. In order to improve the corrosion resistance they are usually coated, mostly by hot-dip galvanizing. In the present work two IF steels purposely designed for a specific continuous hot-dip galvanizing line are investigated. The employed methodology, based on physical simulation, is presented and discussed in the paper. Its reliability is demonstrated by comparing some experimental and industrial results. The simulated specimens are tensile tested and the effects of annealing temperature and line speed on their mechanical properties are evaluated.

Inconel 718, a precipitation hardenable nickel-base alloy, is a versatile high strength, weldable wrought alloy that is used in the gas turbine industry for components operated at temperatures up to about 1300°F. The nominal chemical composition is 0.6A1-0.9Ti-19.OCr-18.0Fe-3Mo-5.2(Cb + Ta)- 0.1C with the balance Ni (in weight percentage). The physical metallurgy of IN 718 has been the subject of a number of investigations and it is now established that hardening is due, primarily, to the formation of metastable, disc-shaped γ" an ordered body-centered tetragonal structure (DO2 2 type superlattice).
