This work presents the project of the application of Case-based reasoning (CBR) methodology to an advisory system. This system should give an assistance by selection of proper alloying additives in order to obtain a material with predetermined mechanical properties. The considered material is silumin EN AC-46000 (hypoeutectic Al-Si alloy) that is modified by the addition of Cr, Mo, V and W elements in the range from 0% to 0.5% in the modified alloy. The projected system should indicate to the user the content of particular additives so that the obtained material is in the chosen range of parameters: tensile strength Rm, yield strength Rp0.2, elongation A and hardness HB. The CBR methodology solves new problems basing on the solutions of similar problems resolved in the past. The advantage of the CBR application is that the advisory system increases knowledge base as the subsequent use of the system. The presented design of the advisory system also considers issues related to the ergonomics of its operation.

Opisano badania wytrzymałości na rozciąganie krzepnącego siluminu Al-Si5Cu3MgMn. W pomiarze rejestrowano siłę rozciągającą i wydłużenie testowego odlewu oraz temperaturę na przekroju jego ścianki. Badano wpływ dodatków stopowych na wytrzymałość krzepnącego stopu. Badania prowadzono na stopie niemodyfikowanym oraz modyfikowanym kompleksowo strontem , tytanem i borem.

The examinations of tensile strength of solidifying AlSi5Cu3MgMn alloy have been described. The tensile force, extension of test casting and temperatures of his wall are in measurement registered. The influence of alloying elements on tensile strength of solidifying alloy has been examined. The examinations have been carried out on unmodified and modified alloy (by complex-addition of strontium, titanium and boron).
