اولین بار در سال1878 میلادی شخصی به نام چرنف از کشور روسیه پیشنهاد کرد که برای انجماد تحت فشار می توان از نیروی بخار آب استفاده کرد. اولین تحقیق مستند در مورد تاثیر فشار بر روی انجماد مذاب آلومینیوم-سیلسیم به سال 1931 توسط ولتر برمی گردد. با توجه به نیاز کشور به تولید قطعات با کیفیت و استحکام بالا مخصوصا از فلزاتی مانند آلومینیوم که نسبت استحکام به وزن بالا دارند، تصمیم بر اجام این پروژه گرفته...
15 صفحه اولModeling of the Effect of Temperature, Frequency, and Phase Transformations on the Viscoelastic Properties of AA 7075-T6 and AA 2024-T3 Aluminum Alloys
The viscoelastic response of commercial aluminum alloys 7075-T6 and 2024-T3 as a function of temperature is presented. Experimental data are obtained with a dynamic-mechanical analyzer (DMA) at different loading frequencies and compared with the available transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) data. The effect of successive microstructural transformat...
متن کاملFatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
متن کاملEffect of Aging Condition on Semisolid Cast 2024 Aluminum Alloy
2024 Aluminum alloy was squeezed cast by the Gas Induced Semi Solid (GISS) process. Effect of artificial aging on microstructure and mechanical properties of this alloy was studied in the present work. The solutionized specimens were aged hardened at temperatures of 175°C, 200°C, and 225°C under various time durations. The highest hardness of about 77.7 HRE was attained from specimen aged at th...
متن کاملAnalysis of Local Microstructure and Hardness of 13 mm gauge 2024 - T 351 AA Friction Stir Welds
The friction stir welding process has been used to join 13mm gauge 2024-T351 aluminium alloy plates together. A detailed microstructural study of the resulting weld was carried out using Differential Scanning Calorimetry (DSC), hardness testing, Scanning Electron Microscopy (SEM) and Electron Backscatter Diffraction (EBSD). DSC was used to explain the hardness results at a number of regions acr...
