Integrating Jominy End - Quench Test Apparatus From Senior Design Project To Mechanical Engineering Labs

An important element of engineering teaching is related to laboratory investigation focused on real life applications via experimental learning. Labs are introducing opportunities for students to practice and participate in scenarios that could enhance their professional experience while preparing them for engineering careers. A group of two mechanical engineering and one industrial management students designed, manufactured and implemented a Jominy end - quench test apparatus in conformity with ASTM Standard A255. The testing equipment will be further integrated into an engineering lab where students can investigate the effects of heat treatment processes and measure the hardenability of various types of steels. In the frame of the lab settings and using available furnaces and Rockwell hardness testing, students will assess the influence of the steel alloy composition on the capability to transform in depth to martensitic structure. Students will be able to gather hardenability curves and discuss the steel quenching potential as well as the probable variations in collected experimental results. The Jominy test apparatus was manufactured according to standard requirements and consists of water pump, pipe systems, enclosed fixtures and support for holding the test specimens. In order to ensure the successful design, construction and implementation of the Jominy apparatus senior design students are using concurring knowledge of fluid mechanics, materials science and heat transfer in addition to industrial management for planning, production, optimization, ergonomics and safety.
