The effect of rotational speed on flow behavior and weld properties in friction stir welding of pure aluminum
(Trans Tech Publications, 2013)
Friction stir welding is a solid state green welding technique. Its key benefit is to allow welding of aluminum that cannot be readily done by fusion arc welding. In this study, two pure aluminum strips of 2mm thick were ...
Comparison of liquid phase sintering and Cu-melt infiltration methods to consolidate 80W-Cu composite using nickel as sintering activator
(Trans Tech Publications, 2013)
In this article, studies were conducted to evaluate the densification of W- Cu sintered compacts produced using two methods; liquid phase sintering (LPS) and combination of liquid phase sintering and liquid infiltration ...
The effect of iron fillings waste contents on the attenuation level of anti-radiation shielding concrete
(Trans Tech Publications, 2013)
Shielding concretes of different iron filling contents were assessed for their anti radiation attenuation properties. The measurements have been performed by using gamma spectrometer of NaI (Tl) detector, the sources were ...
The effect of various waste materials' contents on the attenuation level of anti-radiation shielding concrete
(MDPI, Basel, Switzerland, 2013)
Samples of concrete contain various waste materials, such as iron particulates, steel balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The ...
