DO YOU REALLY NEED TITANIUM GOLF CLUBS?Justin Sickles and Robert A. WesolowskiCarnegie Mellon University MRSEC DMR-0079996 NSF High School Teachers Summer Internship With the exception of the defense industry, perhaps the most competitive area of metallurgical research is sports equipment. Massive research efforts and monies are utilized in developing lighter, stronger, faster, better equipment designed to out-skate, out-ski, out-bike, out-drive, out-last, and out-perform the competition. Materials Science and Engineering has extensive applications throughout industrial processes, and this project introduces high school science students to the role of Materials Science and Engineering in the design and development of sports equipment. The activities involve student experimentation with the objective of observing and comparing the properties of three materials commonly used in the construction of sports equipment – aluminum, stainless steel, and titanium. The answer to the question posed in the title is obvious from the results. image:crush test results representing initial and final states of each material (1.5cmlength samples of on half inch tubing): left samples: aluminum before and after application of 8,000 N force center samples: stainless steel before and after application of 16,000 N force right samples: titanium before and after application of 21,300 N force
