  • Glass technology, batch calculations
  • Glass melting and forming
  • Glass properties such as density, hardness, viscosity, thermal expansion coefficient, chemical durability and engineering principles such as annealing, strength and strengthening
  • Elementary fracture analysis

Recent Innovations in Electroceramics and Their Applications
8:00 a.m. – 4:30 p.m.

Instructor: R. K. Pandey, Texas State University

Description
: Electroceramics has become an integral part of many emerging technologies because of the innovations made in the field in the last decade. Because of the advent of multifunctional oxides, multiferroics, energy harvesting, micro-electro-mechanical systems (MEMS), nanostructured ceramics, spintronics, radhard electronics, bioelectronics, detectors and sensors etc., electroceramic materials have gained in importance and are likely to impact many emerging technologies. The objective of this course is to expose the students to the current state of knowledge in this field with emphasis on practical applications and potentials for inventions.

Key topics include:

  • Introduction to recent innovations in Electroceramics
  • Discussion of interacting forces giving rise to some unique phenomena found only in electroceramic materials
  • Processing and characterization of materials for low cost R&D
  • Physical basis for multifunctional materials and multiferroics and their applications
  • Nonlinear dielectrics and magnetics and their applications
  • Electroceramics for energy harvesting, energy storage, MEMS devices, ceramic based microelectronics devices, sensors and detectors

Attendees will be provided with detailed handouts covering the topics in advance as well as during the lecture.

Understanding Why Ceramics Fail and Designing for Safety
8:00 a.m. – 4:30 p.m.

Instructors: Steve Freiman, Freiman Consulting Inc. and John J. (Jack) Mecholsky, Jr., University of Florida

Description: Engineers who use ceramic components, whether in electronic, optical, or structural applications, recognize that their brittleness can result in damage and possible mechanical failure. In this course we will explore the practical fracture mechanics background necessary to understand brittle failure, and describe some of the unique characteristics of ceramic materials which must be taken into account in their design and use. Microstructural effects, which have a major influence on both fracture toughness and strength, will be explored in some detail. The deleterious effects of external environments, particularly water, on crack growth, and the test procedures needed to explore this phenomenon will be discussed. Best practices in the use of both fracture mechanics and strength tests will be reviewed. Quantitative fractographic analysis of failed parts will be shown to be a powerful tool in understanding the cause of failure as well as to quantitatively determine failure stresses that arose in-service. Finally, a modern, computer-driven approach to statistically examine strength distributions for ceramics will be demonstrated. It will be shown that this tool can be used to set service stresses which will ensure safe lifetimes to very low probabilities of failure.

Designing Aluminum Structures
8:30 a.m. – 4:30 p.m.

Instructor: Randy Kissell

Description: This seminar explains how to use the Aluminum Association’s Aluminum Design Manual (ADM), a guide to the design of aluminum structures and structural components. Compliance with Part I of the ADM, the Specification for Aluminum Structures, is required by all US building codes. This seminar is intended to bring you up to speed in the aluminum Specification so you can design with it as confidently as you would in steel or concrete. Since many engishort courses neers don’t know what aluminum alloys and products are available, how they’re specified, or what their properties are, this course begins by familiarizing you with aluminum. Then we address designing aluminum structural members and connections, including tension members, compression members, local buckling, flexural members, fatigue, welded, bolted, and screwed connections, and the effect of welding on member strength. Sample design problems are worked using the Specification for Aluminum Structures.

Microstructures 101 and Beyond
8:30 a.m. – 4:30 p.m.

Instructor: Frauke Hogue, Hogue Metallography

Description: Do you interpret microstructures on a regular basis, for quality control, failure analysis or research? Are you just curious about what the structures mean that you have been seeing all these years or is metallography a new field for you? In any case, this class is for you! It is a one-day version of the 5-day class that has been presented to rave reviews at the ASM Headquarters in Materials Park, Ohio, for the past ten years. The focus is on practical interpretation, NOT theory, phase diagrams, and thermodynamics. There are no prerequisites. We will look at slides of over 100 microstructures and find out and discuss what each structure tells us about the type of material, manufacturing methods used, heat treatment, mechanical properties, and sometimes even failure modes.

State of Materials Design via Additive Manufacturing
8:30 a.m. – 4:30 p.m.

Instructor: Reginald F. Hamilton

Description: The focus of this course is to explore additive manufacturing from a materials design perspective. The selection of a specific process is based on feature resolution and fabrication rate. For example, electron beam processes that utilize wire feeding are capable of producing large features at high fabrication rates. Powder-fed processes produce reasonable feature resolution, while powder-bed technologies produce the highest feature resolution. Present applications primarily take advantage of AM for net-shape part fabrication and the fast production of net-shapes of complex structural hierarchy. A fundamental understanding of the relationships between processing, microstructure, properties, and performance will advance the implementation of additive manufacturing of shape memory alloys. Many complex physical processes occur simultaneously during the interaction between lasers and the material surface. These interactions are primarily governed by laser power, power density profile, pulse duration, and in multiple pulse situations, pulse frequency and duty cycle. Rapid heating and cooling of the structure, melting, solidification, vaporization, deformation of the liquid surface, and the ejection of droplets can occur simultaneously. Though complexities abound, AM unequivocally facilitates compositional and microstructural control.
