Schliep, Colton M. M.S., Purdue University, May 2013. A Qualitative Perspective of Sustainability Across a Supply Chain. Major Professors: Dr. Edie K. Schmidt and Dr. Edward Sweeney.
Using a qualitative approach, this investigation examines perspectives of sustainability concepts and industry experiences from people in various supply chain roles, attempting to answer the question, "How does sustainability, as a practice and definition, differ across a supply chain; and what are its benchmarks?" Participants in the study included 5 working professionals across different industries. Using systems analysis, in depth interviews elicited 12 common themes of the research. Outcomes of the research discuss …

High Speed Turning Of Compacted Graphite Iron (Cgi) Using Controlled Modulation, Tyler Paul Stalbaum
Open Access Theses
Compacted graphite iron (CGI) is a material which emerged as a candidate material to replace cast iron (CI) in the automotive industry for engine block castings. Its thermal and mechanical properties allow the CGI-based engines to operate at higher cylinder pressures and temperatures than CI-based engines, allowing for lower fuel emissions and increased fuel economy. However, these same properties together with the thermomechanical wear mode in the CGI-CBN system result in poor machinability and inhibit CGI from seeing wide spread use in the automotive industry.
In industry, machining of CGI is done only at low speeds, less than V = …
