Alloy element content has an effect on the ductile-to-brittle
transition temperature of a steel. How does increasing the Mn
content of a steel affect the transition temperature?
A) What are cryogenic materials? Show how ductile to
brittle transition zone takes place.
Determine its applicability.
B) Distinguish between thermosetting and thermoplastics
polymers.
C) Discuss the nitriding process.
Whats the difference between fracture surfaces of ductile and
brittle materials? Whats the effect of axial load verse torsional
load on the fracture surface of ductile and brittle materials.
How does glass transition temperature relate to manufacturing
process/ temperature? How does this manufacture then differ between
crystalline vs. amorpohous structure? How does linear vs. nonlinear
polymer effect the glass transition temperature?
A stainless steel alloy is to be analyzed for its chromium
content. A 3.00 g sample of the steel is used to produce 250.0 mL
of a solution containing Cr2O72−. A 10.0-mL portion of this
solution is added to BaCl2(aq). When the pH of the solution is
properly adjusted, 0.145 g BaCrO4(s)precipitates.
What is the percent Cr, by mass, in the steel sample?
Define the glass transition temperature of polymers. If a polymer
has a glass transition temperature of 25 °C, would you expect it to
be a glassy polymer at room temperature?
When adding heat to a substance at its phase transition
temperature, why does the temperature of the substance not change?
What is the energy used for?
