September 29, 2010 - 1:30 PM
Literature search incomplete - AD700 project, turbine operation at 700C Life expectancy of turbine components: 250,000 hours, about 30 years

Materials Selection Criteria:
 * 1) Creep - Larson Miller Parameter: tested at 100 MPa for 100,000 hours at operation T
 * 2) Developed technology
 * 3) Manufacturing ability
 * 4) Moving components = forged. ex. HP rotor; 80K lb casting and 40-42 in diameter - not possible with Ni based alloy
 * 5) Stationary component = cast. Can't air cast Ni, can't cast >100 kg.
 * 6) Inspectability for defects minimum detectable flaw identification using ultrasonic.
 * 7) Tensile strength --> yield strength
 * 8) Impact strength (steel) or fracture toughness (nickel based)
 * 9) Patent licensing - only supplied by 1 company, $ and capability issues
 * 10) Fatigue - thermal, low cycle (casting, big components)
 * 11) Physical properties - thermal expansion (pieces in contact need to match), thermal conductivity, modulus, poisson's ratio
 * 12) Weldable - everything is welded, so can't use gas turbine materials (low life expectancy). Important for crack removal - grind down and weld overlay.

Next Steps:
 * Learn Classes of Ni Alloys, composition, strengthening phase (science direct, patents)
 * 617 - solid solution strengthened - lacks high yield strength
 * 718 - Ni super alloy - particle strengthened, high yield, not usable for high T
 * Nimonic 105 - particle strengthened, better than 718
 * Look up data sheets for properties
 * Haynes
 * Nimonic
 * Carpenter
 * Special Metals
 * Ni @ 700C typically a composite bc $
 * gamma prime strengthened materials more expensive than solid solution
 * Possible - composite rotor:
 * Beginning (1400F) -weld- Middle (1200F) -weld- End (1000F)

If we can't get numbers, we should make educated guesses Look at the improvement of the materials over years and extrapolate the data

=Meeting with Chris Roberts=

September 20, 2010 - 2:00PM
Casing is a static property creep/oxidation/fatigue/cost/welding are important factors bolts are external, welding of sections of rotor together and you can change materials throughout

September 15, 2:00 pm
Start to look at this project from a business point of view Cartech supplies the materials to turbine companies Sell the most material you can

Focus in on what Cartech wants. What materials are going to make the most impact/money What are they shooting for? Focus on one place where we can make a change They want to focus on one area where they can make a difference

Come up with a methodology for the decision making (performance index, etc.) Designing a methodology for the selection of a turbine material

=Meeting with Chris Roberts=

September 15, 2:30 pm
Define property requirements for materials within the turbine High pressure, medium pressure, low pressure sections For each section of turbine, which properties are most important

Cartech could focus on discs and blades Casing, may or may not be of interest

NETL, EPRI, Oakridge

Look for AUSC! just USC is not always the right operating conditions Immature technology. 10-15 years down the road

The group decided to use Celsius and mpa 760C=1400F

=General Group Meeting=

September 6, 2010 - 1:30PM
Discussion of boiler vs turbine: Our project will have one focus, however in the end we want do an economic analysis of replacing material for the entire plant. This will require us to look at the boiler even though we have chosen to focus on the turbine. This type of analysis will require us to make assumptions about the boiler and all other aspects of the plant.
 * boiler information is harder to find while turbine structure, information, and data are well defined
 * can more easily find size, weight, material prices for turbine components
 * industry reps are more willing to talk about turbines

Power plant visit: Economic Analysis Model: What is expected for next meeting:
 * NETL - operates out of Pittsburgh, Morgantown, and Albany
 * Siemens - natural gas turbines
 * Contact: Paul Ohodnicki about local plant visit (NETL)
 * Ideal visit when the plant is shut down so we can see the boiler
 * Have questions ready for representative (what materials they do/do not like to work with, welding, etc.)
 * Initial cost of remodeling power plant plus lifetime costs need to be considered
 * Lifetime considerations: runtime (days/year), emission reductions after remodel
 * All: literature bibliographies by Wednesday
 * Kelly: email Paul Ohodnicki about plant visit
 * All: be ready to discuss WBS with Prof. Heard and Prof. Seetheraman on Wednesday

=General Group Meeting=

September 4, 2010 - 12:30 PM
Kelly and Bri need to join the wikipage Created and discussed the work breakdown schedule Figured out how to embed calendar on the wikipage

Responsibilities for remainder of project: What is expected for next meeting:
 * Justin - Edit and update wiki and keep formatting the same
 * Jono - Calendar updates
 * Rotating meeting minutes among group members - bri, jono, justin, kelly
 * Minutes taker responsible for updating wiki and establishing what is expected for next meeting
 * Finish reading all documents and summarize them on the wiki by Wednesday

**Conference Call with Chris Roberts**

September 2, 2010 - 1:30PM Schedule Specifics Project Specifics For the past 15 years there has been great amount of research into power generation as infastructure of old plants may fail as demand for power continues to increase Some plants have been around for 50+ years and are in need of upgrading to get more out of the fuels being used. Look at components for boiler section and account for heat generation, also can look at steam turbines which do the electricity generation put on the grid Project is generally Boiler vs Turbine - we choose the dierction Boiler would entail conditions outside of the pipe vs inside of the pipe, by products of combustion, and coatings hot zones, etc. - more challenging What are the property requirements? find materials to meet these requirements. Support with experimental data/research What is the cost of these new materials/alloys? best properties vs lowest cost
 * Meeting on Monday with Chris in person to discuss gantt chart and WBS
 * Will do research and choose direction of project by this meeting
 * Setup weekly conference call times with Chris set at 2:30PM on Wednesdays
 * 1) subcritical -60's
 * 2) supercritical - late 70's
 * 3) advanced ultra-super critical - now - need for materials to withstand 1400F and 35MPa

WBS and gantt chart: project is an open literature project - we need to have structure and order to what we research contact companies for oxidation and mechanical data of alloys

In the end we would like to recommend a material with economics considered or propose new novel techniques

=General Group Meeting= **September 1, 2010 - 4:00PM**

Schedule Specifics

 * Contact Chris for alloy specific side of project
 * Set up weekly meetings at 1:30PM on Wednesdays with faculty advisor

Project Specifics
Generally as you increase operating temperature of power plans, you increase efficiency CO2 emissions is very important - look at tax, economic factors as these are big concerns today Look into alternative fuels being used such as oxyfuel which combusts with pure oxygen so that separation of nitrogen after the fact is not necessary Find materials or composites (metals with ceramics?) that may be able to withstand these difficulties Look into thermal barrier coatings to help protect from heat Maybe do a life cycle analysis Look into State of the Art technology and look at advantages and disadvantages of this technology ||
 * operating temps must be able to go up to 1700 from ~1400 for this to happen and the materials now simply cannot take this heat
 * steam can also have corrosive effects
