Abstract
Analysis of reliability of AlSi17Cu5 alloy was carried out using the so-called „permanence measure”. Two-parameter Weibull distribution, defining stability of material features, is its numerical equivalent. Mechanical properties (HB hardness HB, tensile strength Rm, and yield strength R0,2) were selected as parameters for statistical evaluation, whereas inoculation with phosphorus (CuP10) and overheating to 920 oC (separately and jointly) together with intense cooling of the alloy were the factors shaping the influence of technology type. Statistical calculations, preceded by verification of hypotheses on conformity of distribution of the investigated resultant characteristics with normal distribution, were supported with variance estimators, and correlation and regression analyses.
