Investigation Of Surface Topology Effects On Metal Flow Of Aluminum And Steel During Hot Compression, Andrew Richard Matcha
Investigation Of Surface Topology Effects On Metal Flow Of Aluminum And Steel During Hot Compression, Andrew Richard Matcha
Master's Theses (2009 -)
An investigation was conducted to study the effect of die surface roughness and lay on metal flow and the friction factor under lubricated hot compression. 6061-T6 aluminum and AISI 1018 steel rings and rectangular bar stock workpieces were compressed on H-13 tool steel platens of varying roughnesses ranging from Ra 0.25 – 6.1 µm (10 – 240 µin). Each platen was machined in such a way to ensure that the surface roughness would be unidirectional. Platen temperatures of 149 °C and 204 °C (300 °F and 400 °F) were used for all aluminum ring samples whereas platen temperatures ranging from …

Boeing uses composite components for the 777x aircraft. The production of composite parts results in flashing (excess material) that must be trimmed and "thrown away" as scrap. Boeing is investigating means of recycling these scraps. The method proposed for this project is to delaminate and shred the composite material. The delamination process uses a ram to press two claw shaped devices together that bends and deforms the material in opposite directions. The chipper process uses counter rotating saw blades spaced 1/8” apart to produce small shredded material. This shredding material is pyrolyzed (heated) to decay the resin leaving the carbon …

Akron Children’s Hospital and The University of Akron’s Biomedical Engineering Design Team Engineering Forward have paired together to improve medical adapted helmets for post-operative and disabled patients. An issue is the helmets are only produced in a couple of sizes. Also, it is a tedious process to constantly adjust the pressure on the patient’s cranium within a trial-and-error process. Engineering Forward plans to improve the effectiveness of this helmet by creating an adjustable helmet that can read the pressure on a patient’s head. The caregiver can then make the necessary adjustments to the helmet to accommodate the patient. Documents of …
