Abstract
A method for estimating the inclusion content of a metal, the method involving three steps. The first step is to section the metal to create an exposed inner surface of the metal. The second step is to measure the reflectance of the exposed inner surface of the metal. The third step is to estimate the inclusion content of the metal from the reflectance. When a physical property of the metal, such as tensile strength, elongation or impact strength, is related to the inclusion content of the metal, then the physical property can be estimated from the reflectance of the exposed inner surface of the metal.
