Constitutive Equations for Microstructural Features Developed During Solid Particle Erosion of 52100 Steel

Constitutive Equations for Solid Propellants

Mechanical behavior of the Space Shuttle redesigned solid rocket motor (RSRM) propellant is studied from a phenomenological point of view. Motivated by the study of the experimental data three initially isotropic constitutive models have been developed. All models represent the e ect of strain rate, superimposed hydrostatic pressure, and cyclic loading on the stress and dilatation response of t...

Solid Particle Erosion of Thermal Sprayed Coatings

Solid particle erosion is an important material degradation mechanism. Although various methods of coating are tried and used for protection against erosion, thermal sprayed coating for such purpose is the most widely used method. In this chapter, evolution of thermal sprayed coating, erosion testing methods, and erosive wear of thermal sprayed coatings are discussed extensively with emphasis o...

Hardness is the most SOLID-particle erosion is a loss of material during repetwidely used property to correlate with the erosion rates of itive impacts of solid particles and is one of the primary materials. For pure metals, some correlation between erosion reasons for fly ash–borne damage of power generation comrate and hardness has been shown.[4] However, se...

Microstructural Evolution of X45CrNiW189 Valve Steel During Hot Deformation

The hot compression tests were carried on X45CrNiW189 valve steel (X45) in the temperature range of 1000– 1200 °C and the strain rate range of 0.004 – 0.5 s-1 in order to study the high temperature softening behavior of this steel. For the exact prediction of flow stress, the effective stress-effective strain curves were obtained from experiments under various conditions. On the basis of experi...
