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 need to intensify research efforts in the alternative to lead shot
Baba Gowon; Kahtan S., Mohammed, Dr.; Shamsul Baharin, Jamaludin, Prof. Dr.; Alida, Abdullah (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 ... -
Radiation shielding characteristics of concretes incorporates different waste materials
Ali Basheer, Azeez; Kahtan Sadiq, Muhammed, Dr.; Mohd Mustafa Al Bakri, Abdullah; Hana, Ihsan Hasan (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.

Sintering behavior and microstructure evolution of mechanically alloyed W–bronze composite powders by two-step ball milling process
Kahtan S., Muhammed, Dr.; Azmi, Rahmat, Prof.; Khairel Rafezi, Ahmad, Dr. (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 ...
