An Improved Custom Development Process Utilizing Lean Methods And Tools, Lisa Gay Smith
An Improved Custom Development Process Utilizing Lean Methods And Tools, Lisa Gay Smith
Masters Theses
Works have been written on the applications of lean principles and methods to product development, manufacturing, and the office. However, works written on the applications applied to research and development and custom product development processes have been exclude because of the inherent variability in the product design process. This work applied lean principles and tools to custom product development processes. A furniture company with $1.3 billion in annual sales, custom product development process was studied and lean principles, behaviors, and tools were applied using a traditional six step approach mixed with nontraditional practices as well. Within the six steps, the …
Refinement Of The Cast Microstructure Of Hypereutectic Aluminum-Silicon Alloys With An Applied Electric Potential, Alexander Joseph Plotkowski
Refinement Of The Cast Microstructure Of Hypereutectic Aluminum-Silicon Alloys With An Applied Electric Potential, Alexander Joseph Plotkowski
Masters Theses
Hypereutectic aluminum-silicon (Al-Si) alloys are widely used in the aerospace and automobile industries because of their low density, excellent wear and corrosion resistance, low coefficient of thermal expansion, good strength, and excellent castability. They are used in applications that typically require a combination of light weight and high wear resistance, such as liner-less engine blocks, pistons, and pumps. However, the performance of these alloys depends on the fineness of their cast microstructure, especially dendrite cell size, primary and eutectic silicon particles. In this study, the effects of applied electric current on the cast microstructure of Al-13 wt.% Si and Al-20 …
