Hi dear,

I need someone who can to write a report for me.  That about Effect of Alloying Elements on Hardenability of Steel.

All the information and data in the attach.   

Thank you 

ASTM Tensile strength for plastic samples. Operator ID Harold Company University of Northern Iowa Laboratory Name Metal Casting Center Rate 1 0.39370 in/min Humidity (%) 50.00000 Temperature (deg C) 18.00 Number of specimens in sample 1 ABC Ltd. 975 Fraser Drive Burlington, Ontario Canada 0 1 2 3 4 5 6 7 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 Tensile stress (ksi) Tensile strain (in/in) Specimen 1 to 1 Specimen # 1 Specimen label Maximum Load (lbf) Tensile stress at Maximum Load (ksi) Tensile strain at Maximum Load (%) Tensile stress at Yield (Zero Slope) (ksi) Modulus (E- modulus) (ksi) 1 acrylic 750.10 6.00 7.05 6.00 91.86 Page 1 of 1

University of Northern Iowa Department of Industrial Technology Laboratory Project 4 Effect of Alloying Elements on Hardenability of Steel Due Date : March 30, 2015 Lab Objectives Understand the hardenability or Jominy test Study the effect of carbon content on the hardenability characteristic of steel. Investigate the effect of alloying elements on the hardenability characteristic of steel when the carbon content is similar. Materials and Equipment 1 Specimen each of 8620 alloyed carbon steel, 4340 alloyed carbon steel, and 4140 alloyed carbon steel. The specimens should be 4” long and 1” in diameter with a welded washer on one end of the specimen bar. Rockwell hardness tester, equipped with the appropriate indenter and weights to read the Rockwell B and C scale. Heat treating oven capable of 1700 o F (925 o C) Water-quenching tank with ½” diameter nozzle and specimen holder Either a milling machine (preferred) or surface grinder Tongs Ruler Heat resistant gloves and helmet with face shield Hammer and letter punches Safety Note Wear safety glasses at all times when using the laboratory equipment, including hardness tester, heat treating oven, hammer, anvil, and letter punches. Use heat resistant aluminized gloves and helmet with polarized face shield when placing and removing samples from the furnace. Procedure 1. Use the letter punches to stamp identification marks on the ends of each test bar for permanent identification throughout the project. 2. Heat the oven to1700 o F (925 o C). Place the specimens in the oven. To prevent unintentional cooling of the specimens when the door is opened, do not place them close to the door. If possible, place them as far back into the furnace as possible. In addition, do not stack the samples and distribute the samples uniformly in the furnace to allow for uniform heat rates.

3. Allow the specimens to soak at 1700 o F (925 o C) for 60 minutes. 4. Remove one specimen and place the sample in the holder of the water tank. Immediately start the flow of water to quench one end of the test bar. Make sure the water pressure is not too high such that splashing causes incidental cooling along the surface of the test bar. 5. Once the sample has cooled for approximately 10-15 minutes, turn the water off and remove the bar from the fixture. 6. Along the length of the bar, either machine (preferred) or grind a flat surface approximately 3/8” in width. Make sure a cutting (or grinding) fluid is used to prevent accidental alteration of the microstructure and/or properties. 7. Starting at the quenched end, mark with a fine felt tip pen, 1/16” dividers on the flat surface to a total depth of 2”. 8. Change the Rockwell hardness pedestal so it can accommodate a rounded sample. Make sure the Rockwell hardness tester is set for the C scale. 9. Starting at the quenched end, measure and record the hardness value for each 1/16” increment. Support the specimen so the bar remains level with the pedestal and accidental slippage. If the sample is not level, an erroneous hardness value will be recorded. Slippage of the test bar can cause serious injury or damage to the indenter. 10. Repeat steps 4 through 9 for the remaining specimens. Requirements for Laboratory Report The laboratory report will consist of Abstract (150-200 words) Minimum three paragraph introduction discussing the effect of carbon content and alloying elements on the hardenability of steel. (Maximum length of the introduction is six paragraphs) Presentation of data including tables and charts 1. Graph the hardness values for the 8620, 4340, and 4140 specimens as a function of distance. Discussion of findings (Do not exceed three paragraphs) Conclusions (150 words or less) Include in your report the following review and discussion topics. These are guidelines for you to write your report. Do not write answers directly to the question but address the proposed technical issues in your report. How does carbon content affect hardenability? Alloying elements? Is it possible to correlate the Jominy test to cooling rates as a function of bar diameter? Different positions in the cross section of the bars? Demonstrate how this can be accomplished.
