Dr. Mostaed specializes in failure analysis of metallic materials with specific expertise in metallurgy, microstructure design, corrosion, metal deformation/recrystallization, rapid solidification, and additive manufacturing. Dr. Mostaed has extensive experience in development of high-performance metal alloys for extreme conditions such as corrosive environments, overload, fatigue, and high temperature exposure.
Dr. Mostaed is skilled using a wide array of analytical tools and techniques, including metallography, optical and electron microscopy, electron backscatter diffraction (EBSD), X-ray diffraction (XRD), differential thermal analysis, and mechanical testing under static and cyclic loading. His deep understanding of process-structure-property relationships enables him to identify the root cause of failure in materials and devices.
Prior to joining Exponent, Dr. Mostaed was a materials scientist at Uniformity labs, Inc. where he managed the binder jetting Shop and P1 machines and developed new technology for new materials. Specifically, his responsibilities included development of powder spreading and print strategies in metal binder jet 3D printing to improve bed uniformity, print fidelity, part surface quality, and strength. In addition, Dr. Mostaed worked on sintering process adjustment and design optimization to enhance densification and eliminate sintering-induced distortion of the printed parts.
Dr. Mostaed completed his PhD at Polytechnic University of Milan, where he focused on adopting severe plastic deformation strategies for development of ultrafine-grained (UFG) Mg-based alloys for bioabsorbable bone implant applications. He found that UFG Mg alloys exhibit unprecedented mechanical properties, corrosion behavior, and superplastic ductility. Accordingly, he extensively studied the effects of microstructural features including grain size, crystallographic texture, deformation twinning, and secondary phases on mechanical strength, ductility, tension-compression yield asymmetry, and deformation mechanism in UFG Mg alloys. Additionally, Dr. Mostaed formulated and processed high strength, creep resistant, and biocompatible Zn alloys for biodegradable vascular stenting applications. He discovered a superplastic to high-strength behavior transition via microstructure design in Zn-based alloys.
