You're invited to a lecture with Dr. Mona Torabi, a lecturer in the Mechanical Engineering Technology program in the Department of Engineering Technology at Old Dominion University (ODU), Norfolk, VA, titled "Crystalline Structures of Metals."

 Lecture Overview: This lecture will explore into the world of crystalline structures in metals. We will study three of the most common structures: Body-Centered Cubic (BCC), Face-Centered Cubic (FCC), and Hexagonal Close-Packed (HCP). Understanding these structures is crucial for predicting and evaluating various metal properties, such as strength, stiffness, and conductivity. 

Key Lecture Points: 

1. Introduction to Crystal Structures:

a. Definition and importance of crystal structures in metals.

b. Relationship between crystal structures and material properties. 

2. Detailed Exploration of Three Common Structures:

a. BCC: Unit cell description, atomic arrangement, and packing efficiency. 

b. FCC: Unit cell description, atomic arrangement, and packing efficiency. 

c. HCP: Unit cell description, atomic arrangement, and packing efficiency. 

3. Calculation of Lattice Spacing and Number of Atoms:

a. Deriving the relationship between lattice spacing and atomic radius. 

b. Determining the number of atoms in different unit cells. 

Biography: Dr. Mona Torabi is a lecturer in the Mechanical Engineering Technology program in the Department of Engineering Technology at Old Dominion University (ODU), Norfolk, VA. She earned her doctorate in Mechanical Engineering from Clarkson University, NY, in 2018. During her Ph.D. studies, she developed a new product in polymer composite materials for applications in high-temperature, high-pressure environments, sponsored by GE Oil & Gas. This work resulted in US patent applications, peer-reviewed publications, and conference proceedings. Dr. Torabi has experience teaching a wide range of courses in the mechanical and manufacturing field, including computer-aided drafting and solid modeling, mechanical experimental laboratories, strength of materials, material science, and manufacturing processes. Dr. Torabi combines expertise in mechanical analysis, fatigue, fracture, and thermophysical analysis. With a background as a process and CAD-Design engineer, she brings industrial experience to mentor capstone projects. She advises senior design projects and mentors students in 3D printing research at ODU. She has also served as a reviewer for the International Association of Journals and Conferences and the American Society of Engineering Education Annual Conference. Dr. Torabi is an active member of several department and university committees and involved in college and university outreach activities. In support of student professional development, she recently became the advisor of the ODU ASHRAE Student Chapter.
