摘要
A method for quantitatively judging the features of texture based on the number of graphites of graphite texture and the fatness of constitutional graphite in gray cast iron. More specifically, only nonspherical graphite having a mean diameter of 5 mum or above is extracted from a preprocessed image of a graphite texture and its count is calculated (step S5). Furthermore, only such graphite as having a maximum length in the range of 50- 150mum is extracted and the length and area of individual graphite are measured (step S6). Representative graphite of a graphite group having a maximum length (maximum diameter) of 100mum is assumed from these data and then its area is determined and divided by the length of 100mum thus obtaining the fatness (step S7). Value of the fatness is displayed together with the number of graphites (step S8).
