My old boss, Henton Morrogh, was the original inventor of nodular (SG or ductile) cast iron. His method, however, never really caught on because he used Cerium instead of the more commonly used Magnesium as the element that changed the microstructure from flake to nodular graphite. His was still the first to produce nodular cast iron. He became a Fellow of the Royal Society for his work in metallurgy. He was my hero and mentor when he was head of BCIRA (British Cast Iron Research Associatio). His input helped me write many metallurgical papers, one of which being 'The influence of Manganese and Sulphur on the structure and mechanical properties of grey cast iron'.
