Orange County Chapter of SAMPE

Virtual Meeting Notice

Wednesday, January 18, 7:00 PM PST

AlphaSTAR, an engineering software company, provides innovative physics-based simulation technologies. As a simulation solution provider, AlphaSTAR’s tools are used to address real-life scenarios in the aerospace, automotive, defense, energy, and discrete manufacturing industries, worldwide. With over 30+ years of developing cutting edge tools, we help companies by improving product quality, reducing manufacturing cost and accelerating time to market. AlphaSTAR is the recipient of esteemed industry and technology awards for R&D and software development and is a proud women-owned business.

An effort utilizing Integrated Computational Materials Engineering (ICME) technology to support Grain Boundary Engineering (GBE) for Additive Manufacturing (AM) will be presented.

            AM creates several complex thermal processes which alter mechanical properties in terms of strength and plasticity.  The property changes are related to material microstructure changes generated as a function of nanoparticle inclusions, thermal cycling, and controlled phase changes. In this study, GBE multi-scale modelling is performed to improve material properties and expedite the qualification process for existing and new AM polycrystalline alloys. A novel technology is developed to create new alloys for AM by mixing small quantities of nano-particles with bulk material during an AM process. Ultimately the developed ICME technologies can reduce “Trial-Error” by establishing the coveted AM “Digital Twin”. 

Accordingly, three innovations have been established by ICME Support (1) AM Post Heat Treatment; (2) meltpool optimization using intrinsic heat treatment (IHT), and (3) ICME New Alloy Design Supported by the intelligent use of Inclusions, generation of precipitates and variation in build processes. 

Our presenter,Dr. Rashid Miraj, is the Director of Technical Operations at AlphaSTAR.  His primary responsibility is government relations, business development and corporate outreach.  Dr. Miraj holds a BS (1984) in Mathematics from the University of Maryland, M.S. (1987) in Mechanical Engineering from Columbia University and Ph.D. (2004) in Mechanical Engineering from the George Washington University.
