Quality of Casting and Heat Treatment esses - an Information Transfer Approach

摘要

The present paper [0] presents a stochastic analysis - based on the principle of probability transfer and Markov modelling - aimed to clarify one of the most usual discarding/ scrapping causes in the case of an Al-HPDC (aluminium high pressure die casting) process: the material anisotropy. This anisotropy is especially reflected by the higher dispersion of the elongation compared to the yield strength. When submitted to a heat treatment a part shows acceptable values for the yield strength and not acceptable or only partial acceptable values for the elongation. The question to answer is if the Heat Treatment (HT) has been properly applied. The answer could be profane: if a specimen shows perfect values and 1 cm aside (under comparable geometrical conditions) the elongation is not acceptable although the yield strength is, then it has to be "something else".
