Journal of Synchrotron Radiation, Volume 33, Issue 1, Page 181-194, January 2026.A high‐speed X‐ray microscope design optimized for white beam synchrotron radiation enables real‐time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF‐EB) of high‐Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni‐based ...

Production of nanograined intermetallics using high-pressure torsion
Materials Research, 2013 Formation of intermetallics is generally feasible at high temperatures when the lattice diffusion is fast enough to form the ordered phases. This study shows that nanograined intermetallics are formed at a low temperature as 573 K in Al- 25 mol% Ni, Al ...

The Ni-Al-Hf Multiphase Diffusion
Archives of Metallurgy and Materials, 2016 The generalized Darken method was applied to simulate the diffusion between γ-Ni| γ’-Ni3Al and γ’-Ni3Al|β-NiAl interfaces. The results of calculations were compared with the experimental concentration’s profiles of nickel, aluminum and hafnium in ...

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.This work reveals the phase composition and quantitative morphology analysis of precipitation‐hardened Fe32Cu12Ni11Ti16Al29 complex‐concentrated alloy. The precipitates are shown to have a high coherency. Morphology transition between sphere, cuboidal, and elongated morphology is observed. Finally, the overaging behavior is captured using microhardness.

Advanced Engineering Materials, Volume 27, Issue 24, December 2025.Rotary friction welding of steel E355 and the aluminum alloy EN AW‐6082 can lead to the formation of brittle intermetallic phases. The primary process parameters are varied in order to determine their influence on this intermetallic phase formation and the resulting mechanical properties.
