Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Ambiente receptivo uterino: control materno, control embrionario, muerte embrionaria

open access: yesRevista MVZ Córdoba, 2010
El ambiente receptivo en el útero, o ambiente embriotrófico, se define como la capacidad del organismo materno para hospedar el conceptus exitosamente. La receptividad uterina depende de la correcta sincronía del eje conceptus - cuerpo lúteo - endometrio y está controlada por dos mecanismos. El primero depende de la madre y se establece a través de las

Microstructure Design of Steel‐Spinel Composites via Spark Plasma Sintering Process

open access: yesAdvanced Engineering Materials, EarlyView.
This study illustrates how spark plasma sintering at reduced oxygen partial pressure enables controlled formation of steel‐spinel composites through tailored redox reactions and cation exchange. Comparison of the MgO–Fe2O3, steel–(MgO+Cr2O3), and steel–(MgO+Fe2O3) systems shows how oxygen activity and interface chemistry govern spinel formation, phase ...
