Effect of aging temperature on the intermetallic compound (IMC) formation of Sn-0.7Cu/Si3N4 composite solder
(Trans Tech Publications, 2013)Nowadays, excessive growth intermetallic formation becomes the major issue in electronic packaging industry. The investigation on the effect of aging temperature to the intermetallic compound (IMCs) growth formation for ... -
Radiation shielding characteristics of concretes incorporates different waste materials
(Trans Tech Publications, 2014)Samples of concrete incorporate different waste materials such as iron filings, iron balls of used ball bearings and slags from steel industry were assessed for their anti-radiation attenuation coefficient properties. The ... -
The need to intensify research efforts in the alternative to lead shot
(Trans Tech Publications, 2014)The problem of lead poisoning resulting from the use of lead shot in hunting waterbirds and shooting sports has led to the partial ban, voluntary restriction and complete ban of lead shot in some countries. The ban resulted ... -
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 ... -
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 ... -
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 ... -
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 factors affecting the swelling of W–bronze composite system at different sintering conditions
(Scientific.Net, 2012-12)During sintering of Wbronze metal matrix composites, the difference in the interdiffusuion path, sintering atmosphere and alloying element might be the source of the swelling phenomenon. In this study, the factors lead to ... -
The role of the activator rich-W interboundary layer on liquid phase sintering of W-pre-alloy bronze composites of Fe and Co additions
(Elsevier B.V., 2012-11)In this study, the effects of 1-3 wt.% Fe and Co additions on the sintering of W 40-80wt.%-pre-alloy bronze Sn 10 wt.%-Cu compacts were examined. The isothermal part of the sintering process was conducted at temperatures ...
