15 صفحه اولInfluence of Aging Temperature on Mechanical Properties and Sound Velocity in Maraging Steel M350
In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
متن کاملeffect of thermal accelerated aging of mixed hardwoods cmp paper on mechanical and optical properties of its recycled pulp
the old newsprint, as an important grade of waste papers, usually has been produced from chemicalmechanical pulp (cmp). although the effect of paper aging on different properties of recycled pulp has been investigated from long time ago; but, few studies have been observed about the effect of this phenomenon on recycling of cmp paper. in this study, accelerated aging was applied on hardwood cmp...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
