“Young Adults Powerful Beyond Measure”

Professor Elias

MSE 302

-
Metallurgy is the study of metals, and
their different processing and
manufacturing for different
applications.


-
Processing methods are vast, and
can range from cold
-
working, heat
treatment, quenching methods,
cooling times, coatings, and alloying
etc.


-
Each processing method produces a
unique metal, with unique properties
specific to an application, or tool used
by the masses.

Three general types of carbon steels


1. Low Carbon


2. Medium Carbon


3. High Carbon



1. & 2. have most of their use in
infrastructure, serving as the skeleton for
commerical

building/high rises due to their
ability to deflect without
catastrophic/immediate fracture.



3. Is used in applications where constant
usage, and punishment occurs to the metal.
Crankshafts for vehicles, dies for industrials
molds, and industrial machinery such as the
blades of saws, cutters, etc.

-
Alloys are metals that have been mixed/processed
with other metals to produce a final “alloyed metal”
that has mixed and enhanced properties.



-
Stainless
steel,example

of a very common alloyed
metal.
M
ain purpose to be able to withstand
corrosion. Usually alloyed with varying amounts of
Chromium, Nickel, and Molybdenum, and subject
to different heat
-
treatment processes.



Three main types of stainless steels:


1. Austenitic


2.
Ferritic


3.
Martensitic



1.
M
ost common, great anti
-
corrosion properties, can
get rather expensive.


2. Not as anti corrosive as Austenite, usually much
cheaper.


3. Not the most anti
-
corrosive, due to heat treatment,
produces a very tough metal that can hold edge. Used
in cutlery. However, it can be very brittle.

o

Identify, troubleshoot and fix the biases that women face in the field of



Materials Science Engineering


o

At School:


Problems


Little bias between sexes


Rigorous course load discourages them


Solution



Come a variety of fields such as: Chemistry, Physics and Math



o

The work place


Problems:


Higher possibility of sexism


Study equal opportunity policies and their effectiveness


Solution: Recommends Universities and Companies

Statistics

P.HD’s in Material Science Engineering for women increased 21% from
1983


2006


Julian Hipolito



Artist


Broke her own Swan Statue


Inspired her to create unbreakable
plaster


After 8 years she perfected a
Renaissance recipe
Geobond
® a
catalyst of milky additive with
gypsum and concrete


PROPERTIES: indestructible, fire
-
proof and non
-
toxic


Patented in 1997


Replaces asbestos in building
materials


“Corporate America needs to clean up its act. The
labeling on building materials for home construction is
often erroneous and the materials can be dangerous.”

She said after turning a 45 million dollar sale.

Jessica Reichers


B.A. in chemistry @ Carnegie Mellon
University


Temporary research position @ DuPont


1971 discovered a liquid crystalline
polymer solution which led to Kevlar ® 5x

corrosion and flames,


Used as bulletproof vest, skis, safety
helmets, hiking, camping gear and
suspension bridge cables (200
applications)


She's received the
Kilby

award, the
national medal of technology and 1999

“Girls should follow their
dreams. They can do
anything anybody else can
do. They have many more
role models today


not
the least of whom might
be their mothers.”

Mildred
Dresselhaus

was born in The Bronx,
New York and is currently a professor of
Physics and Electrical Engineering at MIT


Grew up during the depression and worked
at age 8


Completed her Ph.D. degree at the
University of Chicago, with her Ph.D. thesis
in 1958 on the subject of microwave
properties of superconductors in a magnetic
field


In 1968, created a new model for the
electronic structure of graphite and graphite


In 1970 she co
-
founded the Women's Forum
at MIT and received a Carnegie Foundation
grant to encourage women's study of
traditionally male
-
dominated fields, such as
physics and engineering



Graphene

is a good thermal and electric
conductor and can be used to develop
semiconductor circuits and computer parts


Future applications include environmental
sensors, flexible solar cells, touch sensors,
stretchable electrodes, foldable displays, RF
applications, etc.


Some conspiracy theorists have even linked
it to materials at the Roswell "crash site"


"Our research establishes
graphene

as the
strongest material ever measured, some 200
times stronger than structural steel,"
mechanical engineering professor James
Hone, of Columbia University, said in a
statement

Between 1966
-
2001, the number of women earning
science and engineering degrees at all levels of
education has increased!


As of 2001, women received half of all science and
engineering bachelor’s degrees, gaining closer balance
with males.


Graduate school number of female students rose over
the years to 41% of science and engineering degree.


In 2001, 37% of doctoral degree recipients were female.


Meanwhile, number of male students dropped between
1996

2001.
