The Hamiltonian Model
The Hamiltonian Model is an analytic model for the study of physical dynamics. It involves the application of Newtons Laws of Motion and works by representing the system under study as a set of equations that describe its behavior. These equations are the Hamiltonian equatio......
Effects of alloying elements chromium, nickel, molybdenum and tungsten in heat-resistant steel
The Heat-Resistant Steels and the Roles of Chromium, Nickel, Molybdenum, and Tungsten
Heat-resistant steels are a particular type of steels that are able to resist the effects of increased temperatures, like a high degree of oxidation and corrosion. Thermomechanical conditions such as exposure to......
