SAMPE Los Angeles Chapter: High Pressure Cold Spray of Metals

Friday, September 23, 2016 at 6:00pm to 8:00pm

California State University, Long Beach, Room 312 6359 E. State University Drive Building ECS, Room 312 Long Beach, CA 90815

Stay on the leading edge by learning about High Pressure Cold Spray of Metals from Dr. Reza Rokni at CSULB.  Plus, see the CSULB research and development laboratories presented by Dr. Ehsan Barjasteh.  Also, interact with other composites and aerospace experts over some complementary pizza and soda.


Featured Speaker and Topic

Dr. Reza Rokni, Postdoctoral Associate
M.C. Gill Composites Center
University of Southern California 


Dr. Rokni joined USC in Oct 2015. He studied at Tehran University, Tehran, Iran, earning his bachelor’s and then Master’s degree in Materials & Metallurgical Engineering in 2004 and 2008.  In 2011, he started his PhD at South Dakota School of Mines & technology (SDSM&T), South Dakota, USA, in Materials Science & Engineering. His areas of interest are related to R&D of additive manufacturing processes including cold spray process, friction stir processing and other severe plastic deformation processes, with especial focus on design-processing-microstructure-mechanical properties relationships.

Dr. Rokni’s main objective through his research has been to perform interdisciplinary R&D on additive manufacturing processes, especially high pressure cold spray, to ensure continuous improvement in repair, refurbishment, and fabrication of parts and components for various industries.  His work has been recognized with several different awards such as, The 2014 Mines Gold Medalist, Best Presentation Award at the 2015 Annual International Thermal Spray Conference, etc.  He has also been involved in humanitarian and leadership activities including being president and treasurer for International Student Inc., and team leader for Food Bank community service society.

Dr. Rokni’s desired goal is to enable US industry to succeed in distributed operations and increasingly complex environments through realization of superior materials processed by additive manufacturing processes, and make the USA a better place for living.



Cold Spray of Metals will be the topic of Dr. Rokni’s talk this evening.


Meeting and Lab Tour Host

Dr. Ehsan Barjasteh
Ehsan Barjasteh, Ph.D.
Assistant Professor, Departments of Mechanical/Aerospace Eng. & Chemical Eng.
California State University, Long Beach
Office: 562.985.2260


Dr. Ehsan Barjasteh will provide a lab tour after Dr. Rokni’s presentation.

Dr. Barjasteh joined the Department of Mechanical and Aerospace Engineering/ Chemical Engineering (joint position) at California State University, Long Beach as an assistant professor in Fall 2015. Dr. Barjasteh obtained his Ph.D. in Chemical Engineering from the University of Southern California in 2011. Dr. Barjasteh has over 10 years Dr. Ehsan Barjasteh of industry experience working on the development and manufacturing of polymer composite materials for commercial and aerospace applications.

Since 2007, Dr. Barjasteh worked and consulted at several companies in California including Composite Technology Corporation, Henkel Aerospace, Tencate Advanced Composites. The focus of his industry career was to develop lightweight products and manufacturing processes to increase the material performance and reduce the manufacturing cost. He also was a visiting scholar at McGill Composite Center at the University of Southern California in 2015. 

Dr. Barjasteh’s research focuses on the development and optimization of advanced polymer and composite materials and processes for commercial and aerospace applications. His research interests include manufacturing of advanced composite materials using out-of-autoclave (OOA) processes, self-healing and repair of composite structure using smart materials, toughening of advanced composite materials, life-time prediction and aging of composite structures, 3D-printing of thermoset and thermoplastic polymers for high temperature applications, and progressive damage detection and analysis.
