Abstract

The basic stages of producing castings of VT40 alloy, doping system, mold, selecting a mode of ingots and forms melting , HIP modes, method of internal defects diagnostics are considered. Particular attention is paid to complex alloying additions of α- and β-stabilizers, as well as additional doping with oxygen and carbon. The effect of doping on the comprehensive strength of the alloy is shown. The advantages of ceramic molds application comparing with graphite ones are considered. It is found that to obtain high-quality castings it is necessary to observe all technological operations.
