The Precipitation of Niobium Carbide and Its Influence on the Structure of HT250 for Automobile Wheel Hubs.

Improving the strength of grey cast iron wheel hubs will improve the safety of automobiles and have a great significance for energy saving and environmental protection. This paper systematically compares the calculation results of Python-based precipitation calculation and JmatPro software simulation with experiments. The results show that with a low mass fraction of niobium (0.
