Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

An investigation of secondary flow in a turbine blade with end wall profiling [PDF]
, 1999 Secondary flows have been long recognised as a significant form of loss mechanism in turbomachinery. They have a major influence over the performance of the blade rows since they cause unsteadiness in the mainstream flow.

NUMERICAL ANALYSIS OF AN AXIAL HIGH PRESSURE PARTIAL ADMISSION TURBINE
, 2022 The transformation of the energy systems will call for new turbomachinery designs for harvesting low-grade heat. The word “low-grade” has many definitions and ranges from levels where steam is the preferred selection to very low grades where specially ...

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...
