Self-compacting high density tungsten-bronze composites
(Elsevier, 2013-07)
Green compacts of W–bronze were encapsulated in shells of bronze powder, placed in a ceramic mold and sintered in alumina tube furnace at 1150 °C. Throughout the sintering cooling stage the differential coefficient of ...
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 ...
Sintering behavior and microstructure evolution of mechanically alloyed W–bronze composite powders by two-step ball milling process
(Elsevier, 2013-01)
The miscibility of W in Sn and Cu is extremely poor. Sintering of W–bronze composites to their full density is proved to be difficult. To tackle this problem, the ball milling process of the W–bronze powder mixture proposed ...
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 ...
