A THERMAL AND ACID TREATMENT FOR CARBON
A Thermal and Acid Treatment for Carbon Extraction from Cast Iron 1316 reduce the oxygen potential in the heating environment. Otherwise, specimens are decarburized rather than graphitized (Park 2008). The control of environment is necessary not only to promote graphitization but also to avoid the loss of iron and carbon atoms by oxidation.
