DESIGN CONSIDERATIONS - COST OF PERFORMANCE CRITERIA Metal Improvement Company is a subsidiary of the Curtiss-Wright Corporation, a diversified international provider of highly engineered products and services to the Motion Control, Flow Control and Materials Treatment industries. INNOVATORS IN TECHNOLOGY Typical examples of premature failure are: l Metal fatigue l Corrosion fatigue l Stress corrosion cracking l Intergranular corrosion l Fretting l Galling l Spalling l Wear The services MIC offer induce residual compressive stresses and so extend component life in a wide range of applications. Shot peening is the most cost effective and practical method of inducing surface residual compressive stresses which enhance the performance and extend the life of critical components. The shot peening process - how it works Controlled shot peening is the bombardment of a surface with small high quality spherical media called shot in a technically defined and controlled way. The shot can be steel, stainless steel, glass or ceramic. Each piece of shot striking the metal acts as a tiny peening hammer imparting a small indentation or dimple into the surface. The action of impinging the surface yields the material in tension, further movement is restrained by the core and a surface residual compressive stress results. The magnitude of the compressive stress is directly related to the yield strength of the base material and is approximately equal to 80% of that value in compression.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
