Direct Observation of Matrix‐to‐Precipitate Elemental Diffusion in Severe Plastic Deformation
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Elemental redistribution, particularly the solute exchange between the matrix and precipitates, is a central issue in alloys subjected to severe plastic deformation (SPD). To elucidate this behavior, a nickel–aluminum bronze (NAB) alloy was processed by high‐pressure torsion (HPT), and its microstructural evolution was systematically ...

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT The thermal expansion mismatch between sapphire and Ti‐6Al‐4V (TC4) alloy has traditionally limited the shear strength of ceramic‐metal joints to ≤ 170 MPa. In this study, active brazing with Ag‐35.25Cu‐1.75Ti (wt%) leads to the formation of a dual‐function microstructure, wherein uniformly dispersed submicron Ti3(Cu,Al)3O particles embedded ...
