Mathematical Model of Autoclave Curing of Epoxy Resin Based Composite Materials
Volume 25, Issue 7 , September 2007, Page 828-835
Abstract
Polymer matrix composites using thermosetting resins as the matrix are increasingly finding use in several applications. Process modeling describing the governing curing has played ... Read More ...Improvement of Thermal Properties for Binary Systems PVFPh, PVF-B by Addition of Silicon Carbide
Volume 25, Issue 7 , September 2007, Page 836-848
Abstract
Two binary systems of (PVF-Ph and PVF-B) were prepared at specificconditions, and then thermal properties were improved by addition of a ceramicmaterial (SiC).A different mixing ratio ... Read More ...Effect of Zn% and Thermomechanical Treatments on the Mechanical Properties of Al-Zn-Mg Alloys
Volume 25, Issue 7 , September 2007, Page 849-862
Abstract
The aging kinetics and the coupling between plastic deformation andsubsequent aging on a set of Al-Zn-Mg alloys having different Zn-content(6.33%, 7%, 7.5% and 8%) are investigated. ... Read More ...Computer Aided Design and Modeling of FCCU Processing Iraqi Feed Stock
Volume 25, Issue 7 , September 2007, Page 863-878
Abstract
The relationships between the process variables for a Fluid Catalytic Cracking unit (FCCU), processing vacuum gas oil (VGO) feedstock from Kirkuk crude oil, were studied depending on ... Read More ...The Effect of Cutting Tool Vibration on Surface Roughness of Workpiece in Dry Turning Operation
Volume 25, Issue 7 , September 2007, Page 879-889
Abstract
his study is to find a correlation between surface roughness and cutting tool vibration in turning. The ranges of process cutting parameters in the present study are limited: cutting ... Read More ...Gain Characteristics of Silicon Transistor Treated by Laser
Volume 25, Issue 7 , September 2007, Page 890-896
Abstract
In this work, profiles of laser-induced diffusion of arsenic in silicon arepresented. These profiles are considered to attempt increasing of the currentgain of silicon transistors. ... Read More ...Cumulative Damage in Fatigue of a Structure Subjected to Random Loading
Volume 25, Issue 7 , September 2007, Page 897-917
Abstract
When a structure is subjected to a random loading, its dynamic response changes, characterized by shifts in the eigenvalues and modification of eigenvectors. The peaks in the dynamic ... Read More ...Improving Oxidation Resistance of Stainless Steel (AISI 316L) by Pack Cementation
Volume 25, Issue 7 , September 2007, Page 918-939
Abstract
The cyclic oxidation resistance of austenitic stainless steel (AISI 316L) can be improved by enriching the surface composition in Al and Si using pack cementation process. In this work, ... Read More ...Effect of Window Over-Hang in Iraqi Building on Cooling Load
Volume 25, Issue 7 , September 2007, Page 940-949
Abstract
A study is done on an Iraqi building to estimate and show how the use ofover hang reduces the cooling load. The study shows how the effectiveness ofover hang is affected by the orientation ... Read More ...دراسة خواص الزحف للمواد المتراكبھ ذات أساس (Al-Mg-Si) مقواة بدقائق من كربید السلیكون
