Application of the Hydraulic Diameter of Interdendritic Space for Calculating the Ultimate Tensile Strength of Gray Cast Iron

Article Preview

Abstract:

A comparative analysis of methods for estimating the gray cast iron ultimate tensile strength σ_u by the hydraulic diameter of interdendritic space D^Hyd_IP and the volume fraction of primary austenite dendrites f_dc is performed. Almost the same accuracy of cast iron castings σ_u estimation according to both these parameters D^Hyd_IP and f_dc of the primary microstructure is shown.
