POST-SPRING BREAK:

Independent lab supplies: Paige will be in SH110 to handout supplies and help with photographing. (BE SURE TO TAKE "BEFORE" and "AFTER" photos!). Only one member of each team need be present to pick up supplies, etc.
Monday, March 14: 2:30-3:30
Tuesday, March 15: 1:00 – 2:15
Wednesday, March 16: 1:00-2:15
Thurs: March 17 1:00-2:15
Once you receive feedback from your instructor, you may begin your independent lab. SH103 will be available starting March 18 for space to set up your experiment. Please see Allen Hansen, Paige or your instructor for access.
The oven for elevated temperature testing (120F) will be available in SH106 starting Monday March 21.

If none of those times work for a single member of the team, please contact Paige Hoffert (hoffertm@up.edu) to set up a alternative.

March 14-17 Welding and Microscopy (if you welded before break, you will do microscopy this week, and visa versa)
YES - WE WILL BE MEETING at 2:40 in SH124 as usual on Monday and Wednesday for the LECTURE portion!
Next week: quiz 2 will be administered (topics: precipitation HT, Jominy testing and HT of steel.). click here for quiz questions
Next week: technical letter (welding, microscopy, etc.) is due next week. Data for the technical letter: sample 1 (85 HRB); sample 2 (68 HRB); sample 3 (56 HRC) --- all photomicrographs are at 1000X. Inclusion of the checklists is optional - but the contentent is required. NOTE: there are graphs in most materials science books showing the relationships between microstructure, carbon content and hardness. It is REQUIRED for this letter to contain such information as a reference! Based on the hardness data of sample 3 alone, you should be able to identify approximate carbon content and microstructure.


March 21-24 Microscopy Discussion/Demo (all students)
*Quiz 2 will be given this week (March 21-24)): precipitation HT, Jominy testing and HT of steel. click here for quiz questions
No assignment due next week. The Independent Lab experiment should be underway.

How to determine elemental content of metals and stars...
Wikipedia - Spectral Lines
Wikipedia - Energy-dispersive X-ray spectroscopy (EDX)
Wikipedia - Auger electron spectroscopy


DUE TO EASTER MONDAY AND FOUNDER'S DAY, the schedule becomes confusing...

March 28-31, April 11-14: RESIDUAL STRESS Lab will be demonstrations of residual stress - there are no assignments for this lab, but you should continue to work on your independent laboratory project, technical letter and oral presentation. Some intersting videos to watch: Glass bead takes a pounding; Glass hammer? Watch the bottle break. FEA of cold working leaving residual stress; on-line Prince Rupert Drops; Myth Buster's - residual stress in glass (10 min)

April 4 - 7 Ductile to Brittle Transistion using Charpy Impact Testing:
Due next week during your normal lab time (regarldess of whether your lab meets or not): technical memorandum. Memoranda (aka "memos") are very similar to technical letters in content; however, the format it somewhat different (see example). Attach to the memo your last graded technical letter (microscopy, welding).
Watching ice grow during our lab: COOL!

April 11-14:
ASSINGMENT DUE next week: Independent lab work (see April 18-21 below for details)
QUIZ 3 next week

April 18-21
INDEPENDENT LAB presentations and technical letter. Quiz 3.
Each team will create and give a formal PowerPoint presentation. Be sure to have a good intro and background - remember, the audience knows little about your subject. Use of photographs and sketches are HIGHLY ENCOURAGED as they can be very effective communication tools!
Provide the instructor printout hardcopies of the PowerPoint slides – 6 slides per page preferred.
For more information on how to give presentations: Mechanical Engineering Student Reference Materials

Also due is a technical letter for your independent lab (1 per team). These letters are the same sort of thing as you've done several times in this class already.

QUIZ: the final quiz will be given the last week of labs. Topics: microstructure, welding, Charpy Impact and DBT, residual stress. click here for quiz questions
