The Effect of Cr Content on the Microstructure and Performance of Heat Resistant Nodular Cast Iron

摘要：

　　By way of alloying,a sort of low-chromium heat-resistant ductile iron material was developed.Through the observation of microstructure,testing of mechanical properties and process performance,heat-resistant test,the microstructure and properties of heat resistant ductile iron of low chromium was studied.The results show that microstructure of the developed heat-resistant ductile iron is spherical graphite distributed regularly on matrix of pearlite and a small amount of ferrite; mechanical properties,processing performance and high-temperature heat resistance of samples of different chrome composition are preferable,but 1.6% of chromium component possess the best performance.
