Description

The refractory industry has been using Hasselman’s principles successfully for many decades, although most of the time empirically. Therefore, the producers and end-users do not need motivation on the subject, though we all need its science. The main objective of the course is to provide the fundamentals and first principles, in order to help the microstructure design of refractories and to understand their behavior under thermal shock.

Topics

Morning: An in-depth view of Hasselman’s approach and Bradt’s and colleagues’ efforts to establish parameters that could model the thermal shock behavior. It will be also presented how all the toughening mechanisms are imbedded in these concepts.

Afternoon: The fundamentals and first principles will be applied, as examples, to the design of complex aggregates and sintered microstructures in the following systems: Al2O3-ZrO2-MgO, Al2O3-ZrO2-TiO2, Al2O3-ZrO2-C-Ti-Si, etc, in order to provide stress induced transformation, microcracking, crack branching and in-situ whiskers.

Learning Outcomes

The fundamentals and examples presented will show that engineered microstructures are mainly related to the first principles understanding and application, which will help to solve production and end-users problems and to design new materials and products.

Audience

Engineers, scientists, students, technicians and managers who are interested on understanding the fundamentals and how they can be applied to design ceramic microstructures.

Prerequisites

None are required. Nevertheless a modest technical background in ceramics, materials science and mathematics at an undergraduate level, would be helpful. The course is intended for a broad spectrum of people willing to learn the first principles and their possible application to refractories and technical or advanced ceramics.

Course Material

Selection of the most significant papers related to the topics to be presented in the course.

Course Includes

2 coffee-breaks, lunch and course materials
