AuE 8660—Advanced Materials for Automotive Applications

Course Description

Advanced structural metals and alloys are revolutionizing a variety of industries, such as the automotive industry, which are reliant upon materials subject to both regular and harsh service conditions. This course aims to provide students with in-depth knowledge of various metallic materials (e.g., steels and iron, aluminum alloys, magnesium alloys, titanium alloys, and metal matrix composites) used in motor vehicles, and fundamental materials science knowledge of composition-process-structure-property relationships, including topics of microstructure, phase diagram and phase transformation, alloying principles, strengthening mechanisms, and heat treatment processes. The influence of material properties on lightweight structural design is also included. Through this course, students are anticipated to learn fundamental and systematic knowledge of metallic materials science, recognize the future of automotive materials, gain comprehensive insights into new material discovery, and obtain practical skills to improve material performance through process and composition optimization.

Topical Outline

  1. Introduction
  2. Microstructure
  3. Phase Diagrams and Transformations
  4. Alloying Principles
  5. Strengthening Mechanisms
  6. Heat Treatment Processes
  7. Steel and Iron
  8. Aluminum Alloys
  9. Magnesium Alloys
  10. Titanium Alloys
  11. Metal Matrix Composites

Course Projects

This course includes two projects.

Project 1 is “Composition-Process-Structure-Property Relationships”. This project will enrich students’ core and fundamental materials science knowledge learned in class for the first half-semester of this course. While a representative metallic material for automotive applications will be selected for this project, the knowledge of Composition-Process-Structure-Property Relationships applies to all species of materials.

Project 2 aims to resolve an application problem that is related to the ongoing industry-related R&D projects using the materials science knowledge learned in this course. Project 2 is aligned with the lecture topics for the second half-semester of this course.
