Functionally graded bimodal Ti6Al4V fabricated by powder bed fusion additive manufacturing: Crystal plasticity finite element modelling

Functionally graded materials: A review of computational materials science algorithms, production techniques, and their biomedical applications

“…They extended their study 68 to determine the mechanical and tribological behaviour of the FG Al/SiC composite. Three different weight fractions (3, 5, and 10 wt%) 48 of SiC particles with two different average sizes (7 and 15 μm) were added to the Al alloy A356. The rotational speed of the mould was 800 r/min.…”

“…(b) Second parameter – lathe thickness of the second phase. 48 Consequently, the relationship between the inverse square root of lathe thickness and the yield stress and the rule of mixture relation between the plastic and elastic properties and phase content was found by crystal plasticity simulations. The authors expanded their research and developed a crystal plasticity algorithm to explain the impact of texture on mechanical properties by adopting a microscopy information-based texture gradient.…”

“…From the results, it is also evident that both the models give almost the same results at the macroscale but not at the microscale, as the discrete model predicted the high value of stress concentration at the microscale in the Ni-Al 2 O 3 FGM system. In 2019, Geng and Harrison 48 did the crystal plasticity simulation of the Ti-6Al-4V microstructural FGM system under two boundary conditions, constant stress and uniform strain. In this study, the FGM was developed using one of the additive manufacturing techniques, powder bed fusion.…”

“…The finished parts were gone through the tensile and shear test, and the output of this test was that the weakest part of the product is an interface between metal and glass. Geng and Harrison 48 investigated the effect of the primary α′ phase content and the secondary αs phase lathe thickness of the Ti6Al4V FGM using a dual-phase crystal plasticity finite element (CPFE) model. The principal phase content varied from 60% to 95%, and the secondary phase lathe thickness ranged from 0.15 μm to 6.20 μm.…”
