dc.description | The mechanical properties of ductile iron (DI) and compacted graphite iron (CGI) are measured and reported on standard machined specimens (as per ASTM). However, most castings retain most of the as-cast surface. This surface layer (the casting skin) includes both surface and subsurface features. Because of the casting skin, the mechanical properties of the part are typically significantly lower than those found on standard ASTM machined specimens. The technical objectives of this research were to identify the individual features that together define skin quality in DI and CGI, to develop a method for the measurement of skin thickness, and to quantify the influence of the skin of thin wall (2 to 6 mm) DI castings on its tensile properties. The features of the casting skin include surface (roughness) and subsurface (graphite degradation, graphite depletion, pearlitic rim) elements. Graphite shape measurements were used to evaluate graphite degradation. Graphite area measurements were used to determine the thickness of the graphite depleted layer. Microhardness measurements are useful when a pearlitic rim occurs. The average thickness of the skin for thin wall DI castings ranged from 0.15 to 0.45mm, while for CGI it ranged from 0.7 to 2.5mm. It was found as expected that the strength decreased with thicker casting skin. The tensile and yield strength skin factor (ratio between the strength of as-cast and machined test plates) was about 0.93. This should be viewed as an upper limit, as only one of the surfaces of the mechanical properties test plate was as-cast. More significant reduction in strength should be expected. Diffusion calculations confirmed that graphite degradation, graphite depletion and the pearlitic rim are the result of magnesium and carbon depletion at the mold/metal interface because of their oxidation. Alternatively, carbon diffusion from the mold can also result in pearlitic rim formation. | - |
