Ceramics As Materials Of Construction
( Qatar University , 1988 , Article)This paper attempts to review the limitations for using the important ceramics in contact with corrosive media. Different types of ceramics are included. Corrosion properties of ceramics and their electrical properties are ... -
A Compressive Strength Criterion for Anisotropic Rock Materials
( Qatar University , 1988 , Article)This paper puts forward a general compressive strength criterion for anisotropic rock materials under multiaxial state of stress. The proposed criterion, is a generalization of the Von Mises yield criterion for ductile ... -
Control of Void Formation During Forging of Advanced Fiber Reinforced Composite Materials
( Qatar University , 1989 , Article)Increased interest has emerged in recent years in the development of fiber reinforced superalloy composite materials and the fabrication processes to produce composite turbine vanes and blades for advanced gas turbine ... -
Corrosion Failures: Identification, Diagnosis & Remedies
( Qatar University , 1988 , Article)This paper deals with the nature, typical surface features and common forms of corrosion. It also reports corrosion rates in various locations and under differing environmental conditions, viz. tropical, marine, urban and ... -
Economic Analysis of Corrosion Control In Petroleum Refineries
( Qatar University , 1988 , Article)Economic analysis of corrosion problems and their prevention or control was found to gain very little importance in the last 10 years according to the published work surveyed. This article surveys the most important work ... -
Effect of sulphates in cement (containing 5% pozzolana) and in sand on the correlation between compressive strength and u.p.v. of concrete of different mixes
( Qatar University , 1990 , Article)Sulphates may be found in any of the raw materials of cement. Sand contaminated with sulphates is currently a local problem because of the difficulty in obtaining well-graded sand which could be used in concrete that has ... -
Electrode Surface Roughness Effect on the Breakdown Characteristics of Compressed Gas Cable
( Qatar University , 1988 , Article)The influence of electrode surface roughness on the breakdown field strength in SFu gas and mixtures is investigated. A coaxial electrode configuration is used to represent a practical gas insulated cable. With the use ... -
Flow and Fracture Behaviour of Tungsten Fiber Reinforced Superalloy Composites-Effect Of Specimen Geometry
( Qatar University , 1989 , Article)The influence of aspect ratio (i.e. width to height ratio) of test specimens on the flow and fracture behaviour of fiber reinforced composites is herein examined. The composite material was prepared by isostatic pressing ... -
Influence of Surface Finish on Fatigue Life of Steel Specimens Subjected to Pure Bending
( Qatar University , 1990 , Article)It has long been appreciated that surface conditions exert significant influence on fatigue behavior. The new capabilities of identifying and measuring surface parameters together with the significant development in data ... -
Investigation of In-Service Parameters Influencing the Wear and Wear Rate for Two Rubbing Surfaces
( Qatar University , 1989 , Article)A study has been conducted on the volumetric wear and wear rate as well as the quality of the surfaces produced by rubbing brass and steel specimens. Effect of end pressure and total sliding distance between the two rubbed ... -
Material Behaviour Under Corrosive Environment — Guide For Material Selection
( Qatar University , 1988 , Article)In this paper, the behaviour of engineering materials as influenced by fluid velocity, operating temperature, humidity and duration of exposure to chemical and/or electro-chemical action is carefully studied, corrosive ...
