March 19, 2020: Congratulations to Dr. Hazeli for receiving a $540,000 CAREER grant from the National Science Foundation for his work with additively manufactured lattice structures! This work involves the development of additively manufactured lattice structures, which allow complex geometric features to be made from high strength alloys, and looks to mimic functions of biological structures, such as crack resistance in bone.

March 2, 2020: The National Science Foundation (NSF) announced that Kavan Hazeli is awarded for the Faculty Early Career Development Program (CAREER) Award. The CAREER Award is the foundation's most prestigious honor for junior faculty members who exemplified the role of teacher-scholars through outstanding research, excellent education, and the integration of education and research within the context of the mission of their organizations. The Award supports our proposal, “CAREER: Understanding the Combined Effect of Microstructure and Topology on the Mechanical Behavior of Additively Manufactured Lattice Structures” for a five-year period from 2020 through 2025. Thank you, NSF, all our supporters, mentors, collaborators, and friends!

This Faculty Early Career Development (CAREER) grant focuses on understanding the mechanical behavior of additively manufactured lattice structures (AMLS). AMLS are hierarchical materials whose effective properties depend upon both the topology of the lattice structure and the base metallic material microstructure. Therefore, understanding the interplay between topology and microstructure is necessary to maximize the potential application of AMLS. In general, one of the major factors that limits a complex engineering systems performance is that conventional structural metallic materials serve a singular purpose of providing structural support. However, flexibility in the design of AMLS enables an array of multifunctional applications, such as controlled heat transfer, vibration, energy management, and light-weighting. In this research, the potential of AMLS will be enhanced with an in-depth experimental-computational investigation of the combined role of microstructure and topology in the mechanical deformation mechanisms that control the mechanical behavior over a wide range of loading conditions. The educational part of this grant will provide: (1) an opportunity to senior design teams to build educational tools and techniques to teach mechanical engineering concepts to people with visual impairment; and (2) a hands-on research opportunity to low-income students.

January 17, 2020: Congratulations to Joe Indeck and Behzad Bahrami Babamiri for their winning presentations at the Alabama Materials Science Student Research Symposium! They took two out of three outstanding oral presentation awards, based on both the quality of the science presented and the quality of the presentation itself.

Congratulations to Andrew Minor for defending his thesis on "Quantification of Porosity and its Effects on the Quasi Static and Dynamic Behavior of the Additively Manufactured Nickel-Based Superalloy Inconel 718."

October 26: Behzad took 1st place for his poster on "Predicting Mechanical Properties of Lattice Structures," with Dr. Kavan Hazeli as his mentor. Poster competition winners were recognized at the VBS luncheon on October 26, 40 students participated in the poster competition this year.

October 24-26: Behzad Bahrami Babamiri will present at the 10th Annual Wernher von Braun Memorial Symposium, organized by the American Astronautical Society in collaboration with UAH.
