Metallurgy and Alloyed Steels

-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.

Carbon Steels -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.

Alloyed Steels -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. Main 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. Most 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.

University Materials Council

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

Patricia Billings & Geobond™

•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.

Mildred Dresselhaus• 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• 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

Andrea Hodge

• Currently: Professor at USC (helping aid female students)

• Research Scientist: Lawrence Livermore National Laboratory

• (works 60/70 hours per week )

• Visited by Japanese scientists. • Focus on Nano Mechanics and

characterizations of Nano crystalline materials

• Her ultimate sacrifice.

Statistics•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.
