The Tikrit Journal for Engineering Sciences is not limited to a specific aspect of science and engineering but is instead devoted to a wide range of subfields in the engineering sciences. While it encourages a broad spectrum of contribution in the engineering sciences, its core interest lies in issues concerning material modeling and response. Articles of interdisciplinary nature are particularly welcome.
The primary goal of the new editors is to maintain high quality of publications. There will be a commitment to expediting the time taken for the publication of the papers. The articles that are sent for reviews will have names of the authors deleted with a view towards enhancing the objectivity and fairness of the review process.
Articles that are devoted to the purely mathematical aspects without a discussion of the physical implications of the results or the consideration of specific examples are discouraged. Articles concerning material science should not be limited merely to a description and recording of observations but should contain theoretical or quantitative discussion of the results.

دراسة تأثير السرعة الدورانية ودرجة حرارة الصب على مقاومة البلى والصلادة لسبيكة الالمنيوم (A380) المقواة بنسب حجمية مختلفة من دقائق الالومنيا


In this study a cylindrical liner was produced by horizontal centrifugal casting process. The liner was composed from aluminum alloy (A380) matrix reinforced with alumina particles (Al 2O3)with grain size of (63−125)µ and volume percent of 10,15 and 20%. The die was rotated at different speeds and its temperature was remained constant at (350)ºC. In this present study it was concluded that any increase in temperature difference between pouring and die temperature will reduce the surface defects. This study reveals that increasing the rotational speed refines the grain size but cause the alumina particles to be concentrated at the outer surface. Finally it was found that the addition of alumina particles increases bothhardness and wear resistance of the alloy.
