Synopsis

This book details the development of a standardized method to produce copper alloy materials with uniform composition and structure to be utilized as spectrochemical analysis standards. The method's significance lies in its ability to overcome the segregation and variability issues inherent in conventional casting or ingot processes. Before this method, spectrochemical analysis was made difficult due to varying composition, structure, and properties of samples. The author provides a detailed account of the planning, preparation, and testing of 15 copper-base compositions for use as National Bureau of Standards spectrochemical standards. The procedure involves casting molten metal on a massive water-cooled plate, resulting in unidirectional solidification and a large disk casting. This allows for the separation of the casting into chill-cast and wrought samples, providing a comprehensive set of standards for both forms. The book also explores the homogeneity and structural differences within the casting and the significance of these differences for spectrochemical analysis. Ultimately, this book presents a valuable method for the preparation of spectrochemical standards, which facilitates accurate and reliable analysis of copper-base alloys.
