Atomic Layer Deposition of Nanostructured Materials

Atomic layer deposition, previously known as atomic layer epitaxy, was once constructed within the Seventies to fulfill the desires of manufacturing fine quality, large-area fl at monitors with excellent constitution and method controllability. these days, developing nanomaterials and generating nanostructures with structural perfection is a crucial aim for lots of purposes in nanotechnology.

In this paper, however, the possibilities of using ICME to achieve a higher process stability and reliability are documented. Especially for aluminum and its alloys, very early process stages, such as the pre-heating before hot rolling already take severe influence on processability and final properties of the strip. Two industrial cases were calculated. In hot rolling it was shown, that the condition of the alloy combined with non-optimal processing parameters can lead to failures of coils after winding.

Thus an accurate representation of the material behavior at different temperatures and strain rates is extremely important to the simulation results. To accurately predict the residual stress and distortion during quenching, the temperature- and strain rate-dependent material constitutive behavior needs to be modeled. Following Newman et al, a material constitutive model called Mechanical Threshold Stress (MTS), was adapted in this work for water quenching process [9]. A. MATERIAL CONSTITUTIVE MODEL During quenching, the total thermal strain can be simply divided into elastic and plastic strains.
