A concurrent finite‐element framework is presented for the design of a patient‐specific AZ31B sub‐orbital osteosynthesis implant manufactured by superplastic forming. The approach couples process simulation and biomechanical analysis to quantify the effects of thickness heterogeneity and grain‐growth‐induced strength degradation.

A New Approach to Characterize Superplastic Materials from Free-Forming Test and Inverse Analysis
For about 60 years, the aerospace industry has been strongly interested in superplastic forming processes to produce extremely light and complex-shaped components.

The study focused on the microstructural evolution and the effects of temperature on the ECAP process. The alloy's response to grain refinement and its relationship with ECAP at elevated temperatures were thoroughly examined. ABSTRACT In the current investigation was to examine how the microstructure of AA5083 changed under various processing settings ...

ABSTRACT This study introduces a novel velocity‐iterative directional annealing (IDA) strategy to overcome stagnation challenges in columnar grain growth of Ti‐48Al‐2Cr‐2Nb alloys. By dynamically adjusting hot zone migration rates across iterative cycles, the IDA protocol achieved 92.2% synchronization between anisotropic α‐grain boundary (GB ...

ABSTRACT The cationic interdiffusion behavior during flash events was investigated using Er2O3/Y2O3 diffusion couples under alternating current (AC) electric fields at different frequencies (50–2000 Hz) with similar specimen temperatures. The diffusion length of Er3+ in the Y2O3 body was athermally enhanced with increasing frequency.
