ASTM A – 10 Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings

Graphite microstructure is useful in predicting the strength and impact resistance of an iron casting at specific locations. One section 1 x 1 x 0. This test method is intended to be applicable for all iron-carbon alloys containing graphite particles, and may be applied to gray irons, malleable irons, compacted graphite irons, and the ductile nodular irons.
