Melt Conditioned Twin Roll Casting (MC-TRC) of Thin Mg-Alloy Strips for Direct Stamping of Mg Components Sanjeev Das1,a, Shouxun Ji1, Omer El Fakir2, Liliang Wang2, John Dear2, Jianguo Lin2, Ian Stone1, Geoff Scamans1 and Zhongyun Fan1,b 1The EPSRC Centre - LiME, BCAST, Brunel University, UB8 3PH, UK 2Department of Mechanical Engineering, Imperial College London, London, SW7 2AZ, UK asanjeev.das@brunel.ac.uk, bzhongyun.fan@brunel.ac.uk Keywords: Magnesium alloy, Microstructure, Twin roll casting, Melt conditioning, Stamping Abstract.
However, addition of GR in the TRC process results in nozzle blockage and upstream nucleation [8], and furthermore, there is currently no effective GR available for Al containing Mg-alloys.

Kaftory et.al take the Beltrami operator as objective functional, and yield a robust algorithm for simultaneous recovery of blurred noisy color images [4].
Dascal et.al propose to apply vector extrapolation methods to accelerate the convergence rate of standard explicit schemes for the Beltrami flow in color.
Etyngier et al. introduce a non-linear shape prior for the deformable model framework learned from a set of shape samples using recent manifold learning techniques [6].
Zhong el al. present an affine-invariant deformable contour in a Bayesian framework.

According to Rush et al., Fe(VI) in water transforms into some intermediates, such as Fe(V), Fe(IV), hydrogen peroxide and other complexes until hydroxides of Fe(III) finally form and oxygen is released[4].
Jiang et al. compared Fe(VI) with coagulants in sewage treatment and found that the removal ef.ciency of total chemical oxygen demand (COD) by Fe(VI) was 5–20% higher than that of the ferric- and aluminum salts used in the same concentration.
Lee et al. [13] examined the dual functions of Fe(VI) to oxidize micropollutants and to remove phosphates using wastewater spiked with micropollutants such as phenols, anilines, amines and ole.ns.
Applying higher Fe(VI) dose, higher COD and TOC removal were achieved, similar to the results reported by Bandala et al..

The overall microstructure of the hot-dip aluminized coating can be categorized into two domains: an outer Al-Si layer and an inner intermetallic layer with the chemical compositions of Fe-Al-Si.
The intermetallic layer formed underneath the Al-Si layer due to Al diffusion into the steel base metal.
These massive crystals are of Al–Fe–Cr–Si, where Al is in major quantity.
As the hot dipping bath of aluminum were containing Al 10 wt. % Si alloy, the deposited coating is in fact a eutectic lamellar structure of Al and Si.

Konig et al. [5] report that cutting forces increase when increasing the cutting speed > 400m/min).
Haddad et al [6] showed that, cutting forces decrease when increasing cutting speed (> 350 m/min), and this is because of the machining temperatures, that are higher than the glass transition temperature.
