Microstructural alteration and oxidation behavior of boronized stainless steel AISI 440C after heat treatments [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2019
The martensitic stainless steel AISI 440C was boronized at a temperature of 950 °C for about 4 hr. Heat treatments at a temperature of 850 °C for about 2-8 hr were performed to eliminate the FeB phase of the boride layer.

Inducing heterogeneity in an austenitic stainless steel by equal channel angular sheet extrusion (ECASE)

Journal of Materials Research and Technology, 2019
An austenitic stainless steel was processed at room temperature by equal channel angular sheet extrusion (ECASE). The microstructure evolution was heterogeneous across the sheet thickness with a higher martensitic transformation in the zones closer to ...

Coupled FE Modeling of Superelastic NiTi Arch Wire and Bone Remodeling to Simulate 3D Orthodontic Tooth Movement During Leveling Phase

International Journal for Numerical Methods in Biomedical Engineering, Volume 42, Issue 10, October 2026.
A 3D FE approach couples superelastic NiTi archwire unloading with alveolar bone remodeling to predict leveling‐phase orthodontic tooth movement. It quantifies the loads applied on individual teeth for controlled tooth movement and is applied to patient‐specific infra‐positioned canine alignment, predicting partial arch leveling with canine extrusion ...
