Material Engineering Career Episode 1

Project Name: INVESTMENT CASTING OF FUTO LOGO USING BRASS

Project Type: Academic Based Career Episode Project

Demographics: This project was a final year project done in July 2009 and completed it in January 2010. The author completed this project with the proper guidance and support of Prof. at the “Name of the university”. This project was based on manufacturing the logo of the university using Brass and Investment casting process.

Engineering Activities of Material Engineer:

  1. To understand the investment casting manufacturing technique and also to know the systematic process to be implemented to manufacture the product.
  2. To calculate the dimension and size of the university logo and implement the calculated dimension to model the 2D design of the university logo in SolidWorks.
  3. To develop the aluminium die with a size similar to that of the university logo and execute the experimental analysis to determine the shrinkage of the brass and wax.
  4. To create the wax pattern with the printed university logo on it by heating the wax inside the mould at the temperature of about 50 0c for 8-10 minutes.
  5. To execute the “chasing” process on the wax pattern to remove the parting line and start the investment of the wax until the desired thickness was obtained.
  6. To manufacture the required product having better surface quality and strength with the university logo imprinted on it by heating the mould at about 1000 0
  7. To record all the results and data obtained from the manufacturing process and report them to the supervisor to know if the manufacturing process was going as per requirement or not.
  8. To have good coordination with the lab operators and supervisor during the time of the project.

Problem & Solutions:

  1. Problem 1 for Career Episode 1 and its solution

University logo was not clearly visible on the wax pattern

The author created the wax pattern with the university logo on it and increased the temperature to 50 0c and heated it for 8-10 minutes. After the estimated time, the author removed the heat and let it be cooled. Once the mould was cooled, the author removed the pattern from the die and found that the university logo was clearly visible on the wax pattern, which was the required pattern for manufacturing the product.

  1. Problem 2 for Career Episode 1 and its solution

Defect like blowhole occurred on the surface of the product

The author reduced the quantity of the gas and provided the venting networks and enhanced the core venting, which would absorb the less amount of moisture. Finally, the author found that the product without any blowhole was manufactured which was the desired structure of the product.

Material Engineering Career Episode 2

Project Name: THE INFLUENCE OF TITANIUM AND ALUMINIUM ADDITION ON THE MICROSTRUCTURE, MECHANICAL AND PHYSICAL PROPERTIES OF LEADED BRASS

Project Type: Academic Based Career Episode Project

Demographics: This project was a final year project done in January 2010 and completed it in June 2011. The author completed this project with the proper guidance and support of Prof. at the “Name of the university”.

Engineering Activities of Material Engineer:

  1. To understand the several methods of the casting, and effect of the addition of the element like chromium and nickel into the brass.
  2. To select equipment and materials for the casting of the brass specimen.
  3. To prepare the test specimen by casting process with various components of the aluminium and tin.
  4. To carry out the microstructural test in the alloy specimen.
  5. To perform tensile, hardness, compressive, thermal and electrical conductivity test in the alloy specimen.
  6. To tabulate and make the graph of the several testing performed on the alloy specimen.

Problem & Solutions:

  1. Problem 1 for Career Episode 2 and its solution

During the compressive test, the value of the maximum compressive strength was found very less. The author investigated the universal testing machine and the author noticed that the clamping jaw was not holding the sample symmetrically. The author checked the surface of the jaw and found the surface of the jaw was irregular, due to which the workpiece was sliding over the jaw. The author contacted with the machine lab technician, and he exchanged the jaw of the universal testing machine with the new one. Further, the author carried the compression testing in the universal testing machine, and the author found the compressive strength of the specimen similar to our expected value.

  1. Problem 2 for Career Episode 2 and its solution

When the author looked at the microstructure of the sample, the author did not clearly saw the arrangement of the several elements over the sample. The author showed the sample to the mentor, and he suggested him to apply less amount of the hydrochloric acid during the etching process. The author took the new sample and performed the grinding and polishing process. During the process of the etching, the author calculated the amount of the hydrochloric acid that has to be applied and the author applied the hydrochloric acid equal to the calculated value. Finally, the author took the sample to the microscope and analyzed the sample. This time, the image was clear, and the author easily differentiated the different element present inside the sample.

Problem & Solutions:

  1. Problem 1 for Career Episode 3 and its solution

The author analyzed the microstructure using a Scanning Electron Microscope during which the author did not find any clear image of the grain structure in the microscope. The author tried with each and every focal length but was not able to obtain a clear image from the obtained alloy pieces. After this issue was faced and to solve it within real time, the author quickly made arrangements for the team meeting with the head of the department, project supervisor and his teammates. At the time of the meeting, the author raised the problem regarding the invisibility of any grain boundaries when observed from the microscope. After understanding the problem completely, his supervisor recommended certain suggestions which helped him to overcome the process. He asked him to use proper etching of the aluminium surface and use the exact method to overcome the rough surface in the surface which caused blurring of the grain structure while observed from the microscope. As per the advice, the author carried out the etching process with high perfection to overcome the blurred surface due to wrong etching technique. The author performed etching and used nitric acid for the smooth and clear surface. After this, the author again inspected the piece of aluminium using a microscope and the grain boundaries were clearly visible. In this way, the author solved the issue regarding grain boundaries within real quick time.

  1. Problem 2 for Career Episode 3 and its solution

The author again found the problem due to the formation of cracks in the aluminium alloy which caused the low strength and hardness. Due to this, the exact strength and hardness along with material properties could not be determined fruitfully. So, in order to overcome this problem of crack formation, the author analyzed the entire process to see if there were any error or mistake repeated during the project. The author also started to analyze the problem using his engineering skills and ideas. Soon after the analysis, the author found a reason for the crack in the alloy. The author had heated these aluminium alloys at more than critical temperature for a long period of time than the required time period. Due to which during the phase of cooling, there were cracks obtained due to molecular deformation in the alloys. Hence, the author heated them up to the required temperature which helped him to lose cracks from the alloy quickly. This was how the author solved the crack problem using his knowledge and engineering skills.
