Wood September 28 2002 DEPARTMENT OF MATERIALS SCIENCE AND ENGINEERING CARNEGIE MELLON UNIVERSITY 27 301 Microstructure Properties September October 2002 LABORATORY MANUAL Experiment No 2 Microstructure Sensitive Mechanical Properties 1 Wood September 28 2002 Introduction Reading There is an enormous literature on this subject The course text by Porter Easterling gives a large amount of useful information Also the text by Tom Courtney Mechanical Behavior of Materials is very helpful Objective of the Experiment The objective of the experiment is to show you the student how to manipulate microstructures in a given material and how strong an effect on the properties this can have This demonstration relies on a classical structural material steel whose behavior can be largely understood in terms of the Fe C phase diagram Ternary additions have a significant effect on the phase transformations and this will be explored in more detail at a later point The reason for choosing the Fe C system is that it contains a rich variety of phase transformation behavior In addition steel is still a widely used structural material You as a materials engineer will be expected to understand and control the properties of materials such as steel Your ability to do this depends on your grasp of the microstructure properties relationships in this and any other system that you deal with In addition to the classical system however you will also have an opportunity to perform similar experiments on various types of wood These will illustrate some of the key aspects of mechanical behavior of composite materials and biomaterials This Document This document contains several sections with general information on mechanical behavior in metallic systems Mr H Greenberg former Industrial Internship Coordinator in MSE is acknowledged for assembling the text It has been retained in order to provide a basic introduction to the relevant materials science for this experiment Students should however expect to
