It has been shown that minute additions of Sn to Al-Mg-Si alloys suppress and/or reduce the negative effect of natural pre-aging on artificial aging. This is of great importance for their application in precipitation hardened lightweight structures, particularly in automotive components. Sn not only retards the hardness increase during natural aging, it also enhances artificial aging kinetics and maximum hardness.

Hot rolling is one of the most commonly used metal forming operation to manufacture long and flat products. In multi-pass rolling proper assessment of the interactions between strain state and microstructure evolution plays a crucial role. Thus, the main subject of the present work is to use multiscale numerical model of hot rolling combining Finite Element (FE) and Cellular Automata (CA) approaches to model multi-pass rolling process.

Mechanical properties of material are closely related to the motion of dislocations, and predicting the interactions and resulting collective motion of dislocations is a major task in understanding and modeling plastically deforming materials. A discrete dislocation dynamics model is used to describe the orientation substructure with in the microstructure.

Scale dependent homogenization is used to estimate the effective properties of heterogeneous materials with Gaussian correlated microstructures. Separation of scales (Micro, Meso, Macro) in these microstructures leads to the problem of determination of Representative Volume Element (RVE) that corresponds to the effective properties of materials.

The mixed system composed by a Sensing block system and a Hopkinson bar is a new method to investigate mechanical properties of materials under high strain rates. In practice, however, wave dispersion distorts pulse shape and may limit the accuracy of results. Using finite element simulation, it is shown in this work that a half sinusoidal pulse decreases wave dispersion. Moreover, it is also demonstrated that the higher the rise time the lower the wave dispersion.
