Abstract
PURPOSE: To carry out measurement quickly and easily by carrying out dye penetrant flaw detection on the surface of a sample head and determining the quantity of the oxide of a metallic material formed based on the measured values of indication lengths.
CONSTITUTION: A mushroom-shaped sample 1 of a metallic material is cast by the low pressure casting method. The lengths of linear indications 8 generated by carrying out dye penetrant flaw detection on the surface of the head of this sample 1 are meausred. From these measured values l1, l2...ln, quantity Q of the oxide of the metallic material is determined from Q=[l1+l2+...+ln(sum of linear indication lengths)]/S (total surface area of sample).
