ME grad student receives two awards

Mechanical engineering graduate student Hossein Taheri recently received two awards in his field of research.

Mechanical engineering graduate student Hossein Taheri

Taheri, a PhD candidate, received a National Science Foundation (NSF) student grant for the POWDERMET2018 and AMPM2018 conferences as well as the R. Bruce Thompson Graduate Fellowship award from ISU’s Center for Nondestructive Evaluation (CNDE).

The NSF student grant will provide Taheri funding to attend the POWDERMET2018 (Powder Metallurgy & Particulate Materials) and AMPM2018 (Additive Manufacturing with Powder Metallurgy) conferences in San Antonio, Texas June 17 through 20.

There, he will present the results from a part of his PhD research about development and application of laser-ultrasound for in-situ quality monitoring of additive manufacturing, or 3D printing, processes. Taheri said this technique helps with in-situ quality assurance of additive manufacturing processes for manufacturing of high-valued metal alloys. The funding will give him the opportunity to interact with more than 200 worldwide powder metallurgy professionals who are presenting the latest research and developments in particulate materials and metal additive manufacturing.

The R. Bruce Thompson Graduate Fellowship is awarded annually to graduate students from CNDE. The fellowship is named for Bruce Thompson who joined the Iowa State faculty in 1980 and served as director of CNDE. He eventually became the Anson Marston Distinguished Professor in the departments of Aerospace Engineering and Material Science and Engineering and authored more than 230 publications during his career.

Taheri said his research on process control and quality assurance of additively manufactured metal parts aims to provide a solution for material testing and evaluation of parts and components for aerospace and other high-reliability applications. His current research is focused on developing acoustic methods for in-situ and in-line monitoring of additive manufacturing processes. He is also developing a numerical model for the optimization of laser-generated ultrasound for inspection of deposited layers during the manufacturing process.

Taheri received his BS mechanical engineering from Shahid Beheshti University in Tehran, Iran and his MS in Mechanical Engineering from South Dakota State University. As a graduate student at SDSU, he worked with Materials Evaluation and Testing Laboratory (METLAB) and focused primarily on the material testing and evaluation methods including mechanical and nondestructive methods.
