Computational Materials Engineering (CME) is a high technological approach used to design and develop new materials including the physical, thermal and mechanical properties by combining materials models at multiple techniques. With the recent advances in technology, the importance of microstructural design in CME environments and the contribution that such an approach can make in the estimation of material properties in simulations are frequently discussed in scientific, academic, and industrial platforms. Determination of the raw material characteristics that can be modeled in a virtual environment at an atomic scale by means of simulation programs plays a big role in combining experimental and virtual worlds and creating digital twins of the production chain and the products. In this study, a new generation, alternative and effective approach that could be used to the development of Al-Si based wheel casting alloys is proposed. This approach is based on the procedure of optimizing the physical and thermodynamic alloy properties developed in a computer environment with the CME technique before the casting phase. This article demonstrates the applicability of this approach in alloy development studies to produce Al-Si alloy wheels using the low pressure die casting (LPDC) method. With this study, an alternative and economical way is presented to the alloy development studies by trial and error in the aluminum casting industry. In other respects, since the study is directly related to the automotive industry, the reduction in fuel consumption in vehicles is an expected effect, as the new alloy aims to reduce the weight of the wheels. In addition to conserving energy, reducing carbon emissions also highlights the environmental aspects of this study.

In order to tailor microstructure to archieve predetermined properties it is necessary to understand and control the processing-structure-property relationships, which is the heart of material science. Electron microscopy has become one of the primary methods of characterizing the micro- and mesostructures of materials, due to its high resolution capabilities now approaching 1A, in real space. In addition, by monitoring the signals generated by both elastic and inelastic scattering, detailed information is also obtainable on the crystal structure and composition of the specimen down to very small volumes, so facilitating analyses of nanostructures, thin films and multilayers in addition to analyses of specimens of bulk materials. In this paper some representative examples of the applications of the electron microscopy towards tailoring microstructure are summarized.
