In this study, an investigation on the main cause of hot cracks in cast Ni-base superalloy, B-1900 and an improvement of its hot crack sensitivity were carried out on the basis of the information about hot cracking phenomena in Inconel 713C. According to the experimental results, it was clear that the main cause of hot cracks in cast B-1900 was low melting pointfine white constituents crystallized at grain boundaries ; the crystallization of white constituents was arrested with an increasing C content ; and hot crack sensitivity of B-1900 under low restraint conditions could be decreased by increasing C content.
