...), and in the automotive industry, to name a few. Significant advances can be made by combining mechanistic studies with increasingly sophisticated finite-element thermal stress analysis. Development of more refined engineering-based models should result in less reliance on component simulation, which is subject to some...

... with a phenomenological model is testing that simulates the wear situation and establishes a correlation. This approach is most often used for materials solutions to wear problems, but it can be used for other parameters, such as roughness, load, or lubrication. Such a test can then be used for rankings. With the use...

... to the deterioration of metal components and result in failure, notably of pressure vessels and pipes. Under certain conditions of temperature and hydrogen partial pressure, atomic hydrogen permeates the steel and reduces iron carbide (Fe 3 C) to form methane (CH 4 ). The methane does not diffuse from the metal...
