An Integrated Model for Prediction of Process-Structure-Property Relationship for Additively Manufactured Al-10Si-Mg Alloy

Exploration of the Underlying Space in Microscopic Images via Deep Learning for Additively Manufactured Piezoceramics

“…As mentioned above, the periodicity of the reconstructed microstructures is induced by adding the circular padding in the generators except for the first upsampling layer. During the calculation of the material properties, e.g., piezoelectric properties of piezoceramics using FSIPM in the present study, RVEs of the microstructures together with periodic boundary conditions are often used to save computing time and efforts. ,,, It is noted that a microstructure without periodic boundaries cannot be used as an RVE. This is because the grains at left/right or top/bottom edges of the microstructure cannot be combined into the same grains, when the grain structure is joined as a periodic unit cell, as marked by red dashed circles in the last two columns of Figure .…”

“…Conventional approaches to reconstruct statistically equivalent microstructures include statistical function-based , and physical descriptor-based numerical modeling methods. , Statistical function-based approaches employ correlation functions and/or lineal-path functions to characterize and reconstruct microstructures. Although they are widely used, potential information loss (e.g., dispersive characteristic) often occurs in the dimension reduction process required to represent high-dimensional microstructures.…”

Crystal plasticity modeling on the selective laser melted AlSi10Mg alloy

“…The negative influence of unevenly distributed and irregular defects on the mechanical properties was verified. Numerous investigations have been performed to understand the structure-property relationship for AM metals considering the great impact of microstructure on mechanical properties [7][8][9]. Particularly, the crystal plasticity (CP) approach has been applied to simulate and understand the mechanical properties IOP Publishing doi:10.1088/1757-899X/1270/1/012024 2 of components with dimensions approaching the grain size of the microstructure.…”

“…The result manifested that the grain morphology has a great influence on the mechanical properties. Yang et al [8] developed a model to study the structure-property relationship for AM AlSi10Mg alloy by considering the presence of porosity. Dream.3D was utilized to generate microstructures with different volume fraction of porosity.…”

“…Various CP theories have been proposed to study the micromechanical behavior for AM parts, while the effects of defect have not been described appropriately so far. Although ideal spherical pores can be added via existing procedure [8], they cannot represent the real LOF defect due to its irregular and varied shape. The current study implemented a CP approach to study the structure-property relationship for the SLM AlSi10Mg alloy, one of popular candidate materials due to its good weldability, small volume shrinkage and relatively low melting temperature.…”
