Kinetics and Tribological Characterization of Pack-Borided AISI 1025 Steel

open access: yesHigh Temperature Materials and Processes, 2017
In this present study, the AISI 1025 steel was pack-borided in the temperature range of 1,123–1,273 K for different treatment times ranging from 2 to 8 h. A diffusion model was suggested to estimate the boron diffusion coefficients in the Fe2B layers. As

Morphology‐Dependent Reinforcement Behavior of Boron Nitride Nanotubes in Aluminum Matrix Composites

open access: yesSmall Structures, Volume 7, Issue 4, April 2026.
This study reveals the critical role of boron nitride nanotube (BNNT) morphology in reinforcing aluminum matrix composites. Fabricated via a combined ball‐milling, sintering, and hot extrusion process, rectilinear multi‐walled BNNTs (R‐MWBTs) demonstrated superior uniform dispersion compared to flexible or barbed BNNTs.
