Rao, Syamala BC and Rao, Veerabhadra P and Rao, Lakshmana NS (1979) Evaluation of Erosion Resistance of Metallic Materials and the Role of Material Properties in Correlations. In: Journal of Testing and Evaluation, 7 (3). pp. 133-146.Full text not available from this repository.
A study of the correlations between material properties and normalized erosion resistance (inverse of erosion rates) of various materials tested in the rotating disk and the flow venturi at various intensities indicates that different individual properties influence different stages of erosion. At high and low intensities of erosion, energy properties predominate the phenomenon, whereas at intermediate intensities strength and acoustic properties become more significant. However, both strength and energy properties are significant in the correlations for the entire spectrum of erosion when extensive cavitation and liquid impingement data from several laboratories involving different intensities and hydrodynamic conditions are considered. The use of true material properties improved the statistical parameters by 3 to 37%, depending on the intensity of erosion. It is possible to evaluate qualitatively the erosion resistances of materials based on the true stress-true strain curves.
