Abstract
Recently, strengthened environmental regulations have required the downsizing of gasoline engines, and as a result, demand for gasoline turbochargers has rapidly increased. The vane of a turbocharger controls the flow of gases toward the turbine, and it is manufactured by powder metallurgy due to its complex shape. Gasoline engines have..... More

Korean J. Met. Mater. 2018;56(4):253-264.   Published online 2018 Apr 5
DOI: https://doi.org/10.3365/KJMM.2018.56.4.253

Abstract
Computational approaches such as first-principles calculations, atomistic simulations, phase field simulations, computational thermodynamics and finite element method simulations are widely used in the metals and materials community. Even with their successful applications for better understanding of material phenomena, and the design of new materials or processes, a gap remains between..... More
