Calculation model of ignition temperature of high temperature titanium-aluminum alloy for aeroengine

Journal of Aeronautical Materials
The ignition temperature serves as a pivotal parameter for assessing the flame retardancy of high-temperature titanium aluminum alloys（TiAl alloys）. Nevertheless，accurately predicting the ignition temperature of TiAl alloys remains a formidable challenge.

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

Advanced 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.

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...

Numerical Modeling of Tank Cars Carrying Hazardous Materials With and Without Composite Metal Foam

Advanced Engineering Materials, EarlyView.
Large‐scale puncture models consisting of hazardous materials (HAZMATs) tank car with protective steel–steel composite metal foam (S–S CMF) are solved numerically. Tank car plate with added 10.91–13.33 mm thick S–S CMF layer does not puncture. Protective S–S CMF absorbs impact energy, reduces plate deformation, and prevents shear bands formation ...

Superelastic nickel-free titanium alloys as materials for dental implants (experimental study)

Клиническая практика, 2018
Superelastic alloys of titanium (titanium-niobium-zirconium and titanium-niobium-tantalum) are more favorable in comparison with titanium for dental implants due to their physico-mechanical properties closer to those of bone tissue.
