CHAPTER 1 INTRODUCTION
Reserve Problem 01a (question pool)
Materials Science and Engineering is the study of material behavior & performance and how this is
simultaneously related to structure, properties, and processing. Which of the following is the best
example of a material property?
(a) Density
(b) Annealing
(c) Forging
(d) Single-crystal
(e) Crystalline
Solution:
Material structure refers to the arrangement of a material’s constituent atoms, ions, molecules, etc.
Material properties are typically either conceptual traits or specific numeric values that describe a
material’s response to applied stimuli. A few examples of numeric property examples are density,
elastic modulus, hardness, tensile strength, and electrical conductivity. A few conceptual properties
include brittle, ductile, and toughness.
Material processing refers to conditions, stimuli, and situations that a material is exposed to, such as
manufacturing steps such as melting & casting, annealing, forging, rolling, cutting, extrusion. It is
often convenient to consider service conditions as processing parameters as well, since factors like
operating temperature, ambient atmosphere, humidity, etc. may further influence a material’s
structure, properties, and performance.
Material performance & behavior typically pertains to how a material responds while in service.
Example: A polycrystalline (structure) steel specimen that has been carburized (processing) should
exhibit a higher surface hardness (property) compared to un-carburized steel. The surface of the
carburized steel specimen will therefore be more difficult to cut or abrade (performance / behavior).

,A thin steel specimen that has been quenched from a glowing red-hot temperature (processing) is
expected to form martensite (structure), the hardest and most brittle form of steel (property). If the
quenched specimen is subsequently loaded, it will not exhibit much strain prior to failure
(performance / behavior).
In this case (b) and (c) are process options, (d) is a conceptual property, and (e) is a structural
description.
Reserve Problem 02a (question pool)
Materials Science and Engineering is the study of material behavior & performance and how this is
simultaneously related to structure, properties, and processing. Which of the following is the best
example of material processing?
(a) Extrusion
(b) Crystalline
(c) Amorphous
(d) Glassy
(e) Elastic Modulus
