3. Mechanical Properties and Microstructural Evolution of AA5083/Al2O3 Composites Fabricated by Warm Accumulative Roll Bonding

Mohammad Heydari Vini; M. Sedighi; Mehdi Mondali

Volume 9, Issue 4 , December 2016, Pages 13-22

  In this study, warm accumulative roll bonding (Warm- ARB) process has been used to produce Metal Matrix Composite (MMC: AA5083/-5% Al2O3). Starting materials were roll bonded as alternate layers up to 5 rolling cycles with 300°C preheating for five minutes before each cycle. The microstructure and ...  Read More

4. Numerical Study of Coupled Non-Gray Radiation and Separation Convection Flow in a Duct using FSK Method

Meysam Atashafrooz; Seyyed Abdolreza Gandjalikhan Nassab; Khosro Lari

Volume 9, Issue 4 , December 2016, Pages 23-38

  In this research, the coupling between non-gray radiation and separation convection flow in a duct is investigated numerically. Distributions of absorption coefficients across the spectrum  are obtained from the HITRAN2008 database. The full-spectrum k-distribution method is used to deal with the ...  Read More

5. An Intelligent Knowledge Based System for CO2 Laser Beam Machining for Optimization of Design and Manufacturing

Morteza Sadegh Amalnik

Volume 9, Issue 4 , December 2016, Pages 39-50

  This paper addresses the concept of CO2 Laser beam machining (LBM) and development of intelligent knowledge base system (IKBS) for CO2 LBM. Feature based design is used for acquiring design specification. For optimization of laser beam machining computer based concurrent engineering environment is used. ...  Read More

6. Investigations on Surface Integrity and Electrochemical Behavior of Machined Co-Cr-Mo Bio-implant Alloy

K. A. Jagtap; R. S. Pawade; K. V. Giradkar

Volume 9, Issue 4 , December 2016, Pages 51-58

  A decisive constraint for the long-term stability of the artificial joint is to minimize the release of debris particles. The wear/debris induced osteolysis and aseptic loosening are the result of failure of metal-on-metal joint implants. SPD processes have been used to adapt the surface integrity properties ...  Read More

7. Pareto Optimal Design of Passive and Active Vehicle Suspension Models

Mohammadjavad Mahmoodabadi; Seyed Mehdi Mortazavi Yazdi

Volume 9, Issue 4 , December 2016, Pages 59-73

  It would be difficult to deny the importance of optimization in the areas of science and technology. This is in fact, one of the most critical steps in any design process. Even small changes in optimization can improve dramatically upon any process or element within a process. ...  Read More

8. Effect of AFM Cantilever Geometry on the DPL Nanomachining Process

Volume 9, Issue 4 , December 2016, Pages 75-80

  With the development of micro and nanotechnology, machining methods at micro and nanoscale have now become interesting research topics. One of the recently-proposed methods for sub-micron machining, especially nanomachining, is dynamic plowing lithography (DPL) method. In this method an oscillating tip ...  Read More

9. Studying the Shear and Discharge Rate of Proteins in Microfluidic Junctions, Under Electrokinetic EffectsStudying the Shear and Discharge Rate of Proteins in Microfluidic Junctions, Under Electrokinetic Effects

Babak kamali Doust Azad; Sasan Asiaei; Borhan Beigzadeh

Volume 9, Issue 4 , December 2016, Pages 81-87

  Changes of hydrodynamic parameters in microchannel branches affect the suspended biological samples in blood. To prevent denaturation and hemolysis, we have numerically investigated the effect of divergence angle on shear rate and velocity at branch entrance (discharge rate), under electroosmotic flow. ...  Read More

10. A New Method for Measuring Perforated Surface by Coordinate Measuring Machine (CMM)

MohammadMahdi Amiri

Volume 9, Issue 4 , December 2016, Pages 89-97

  Nowadays CMM machines are widely used in surface measurement and inspection. As inspection results from CMM machine are obtained by the means of measuring surfaces with direct contact, they are more precise than non-contact method (like optical measurement). However, CMM machines give more reliable and ...  Read More

11. Accuracy Improvement of Upper Bound Analysis of Bimetallic Rods Extrusion Using a New Velocity Field
