Design, Industrial Production and Evaluation of Improved Ductile Cast Iron Alloys Using Computer Derived, Mathematical Models.
Abstract
The investigation attempts to implement a scientific analysis of industrial, mechanical property data on ductile cast iron alloys and design some improved alloys for future industrial production. Several firms donated their data banks for this study and twenty-four of the forty mathematical models generated were derived from information supplied by the Lynchburg Foundry Company. Seventy-five percent of these 24 equations are statistically significant at the 0.001 confidence level, or less, and 53.7 percent of the 82 statistically significant independent, elemental variables which appear in the 12 refined models of this data set behave in accordance with metallurgical theory. Comparison of these industrial results with previous AMMRC findings indicates that, overall, the Army and Lynchburg metallurgical significance levels are within 10 percentage points of one another.
