Comparison of liquid phase sintering and Cu-melt infiltration methods to consolidate 80W-Cu composite using nickel as sintering activator
Hafed, Ibrahim; Azizan, Aziz, Assoc. Prof. Dr.; Azmi, Rahmat, Prof.; Kahtan Sadiq, Muhammed, Dr. (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
Ali Basheer, Azeez; Kahtan Sadiq, Muhammed, Dr.; Mohd Mustafa Al-Bakri, Abdullah; Azmi, Rahmat, Prof. (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 factors affecting the swelling of W–bronze composite system at different sintering conditions
Kahtan S, Muhammed, Dr.; Azmi, Rahmat, Prof. (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
Kahtan S, Muhammed, Dr.; Azmi, Rahmat, Prof. (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 ...
