Description
Summary:Phosphorus is known to have a substantial influence on the structure and mechanical properties of castings and on their service life. The high segregation susceptibility of phosphorus leads to the formation of a low-melting phosphorus eutectic. For this reason, the content of phosphorus in heat-resistant castings (molds, pans) has been limited to 0.2%. In recent years, frequent instability of the chemical composition of charges has led to a situation where iron molds were cast from metal bearing more than 0.2% phosphorus. However, in some cases the heat resistance of the molds did not decrease but even went up. We devoted the present study to explaining this phenomenon and developing a composition of phosphorous cast iron.
