Engineering Reports, Volume 8, Issue 5, May 2026.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 ...

Removal of internal porosity in Supral 150 by hot isostatic pressing [PDF]
, 1985 In recent years, considerable concern has been shown about the effects SPF cavitation has on the mechanical properties of superplastic alloys. This investigation was undertaken to ascertain whether Hot Isostatic Pressure (HIP) eliminated this ...

The development of cavity growth maps for superplastic materials
, 1986 Superplastic alloys usually deform to very large extents but excessive cavitation can lead to premature cavitation failure in these materials. Several mechanisms can contribute to the growth of cavities during superplastic deformation although, generally,

Rare Metals, Volume 45, Issue 4, April 2026.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 ...

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.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.

High strain rate superplasticity in ultrafine-grained Ti-4.5Al–3V–2Mo–2Fe alloy
Journal of Materials Research and TechnologyHigh strain rate superplasticity (≥1 × 10−2 s−1) has been widely reported in low-melting-point materials such as aluminum and magnesium alloys, but remains underdeveloped in high-melting-point materials, particularly titanium alloys.

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.
