Abstract
- The effect of structural defects of wrought semifinished products of vacuum-induction melted alloy KhN55MVTs-VI on service properties is studied. As a result of analyzing the structure using electron microscopy, microdefects have been detected that have an unfavorable effect on alloy ductility. It is established that defects are metallurgical in nature and of casting origin, and they form on aluminum oxide particles distributed through the whole volume of a workpiece. It is demonstrated that vacuum-arc remelting after vacuum-induction melting provides the absence of microdefects of this nature.
