Parameter Variation in Planetary Ball Milling of Titanium Aluminide Powder in XHV‐Adequate Atmosphere

Advanced Engineering Materials, EarlyView.
This study investigates the effects of milling parameters, including rotational speed, milling duration, and ball‐to‐powder ratio, on TiAl particle size and morphology in an XHV‐equivalent atmosphere. The creation of oxide‐free surfaces enhances the mechanical properties of green bodies.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Comparatively Study of Non-Destructive test with different methods in various curing days [PDF]

E3S Web of Conferences
In non-destructive testing, materials, components, or assemblies are inspected, tested, or evaluated without being destroyed. In nondestructive testing, materials, components, and assemblies are evaluated for quality and integrity without damaging them ...

In situ assessment of the stone conservation state by its water absorbing behaviour : a hands-on methodology [PDF]

, 2016
This paper describes the use of the water absorbing behaviour (WAB) for assessment of the conservation state of stone in situ. A test methodology, consisting of a combination of techniques for in situ measurement of the WAB, was applied in a case study ...

Low frequency damping of metal panels in ambient Air [PDF]

, 2008
Mathematical models of structural dynamics are widely used and applied in many branches of science and engineering and it has been argued that many of the shortfalls with these models are due to the fact that the physics of joint dynamics are not ...

Water hammer dissipation in pneumatic slug tests [PDF]

Water Resources Research, 2007
We model and measure the dissipation of water hammer induced by well casing and water elasticity with rapid valve opening at the start of a pneumatic slug test. The higher‐frequency water hammer can obscure slower, aquifer‐controlled, underdamped oscillations of the rigid water column, so a quantitative description of the elastic motion improves the ...

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

Advanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...

Smart non-destractive test of a concrete wall using a hammer [PDF]

International Journal of Electronics and Telecommunications
Large concrete structures such as buildings, bridges, and tunnels are aging. In Japan and many other countries, those built during economic reconstruction after World War II are about 60 to 70 years old, and flacking and other problems are becoming more ...
