Abstract

Presents the results of studies of the uniformity of the distribution of alloying elements in ingots from economically alloyed casting titanium alloy VT40L. Experimental ingots obtained by double vacuum-arc remelting, for which the main technological parameters of melting calculated. Statistical processing of the results of chemical analysis was carried out using Shewhart control charts, and indicators of process capabilities were also evaluated. Suggestions are made about methods for achieving the best stability indicators.
