In this work, Fe-Mn-Si based powder mixture having shape memory alloy composition prepared by mechanical alloying and systematically studied under different milling conditions. Effect of ball to powder ratio (BPR), type and amount of binder addition were investigated as process parameters. All mechanical alloying studies were performed under argon atmosphere and stainless steel balls and vials were used as milling media. X-Ray diffraction (XRD),

The objectives of the normalization of managerial accounting in Romania are presented into detail, from the authors’ point of view, as well as the profile and attributions of the managerial accountant as a normalizer. The article ends with the authors’ conclusions related to the normalization

For eliminating the influence of the fixed costs’sabsorbtion and for a better supervision of other causes of digressions, the managerscan apply the method of rational imputation of the fixed costs. The managers should,in some cases, take into consideration the total costs and not the unit costs. Variablecosts, fixed costs and unit costs should be taken
Read moreA normalized hot forged Cu-15Zn-6Al (mass. %) shape memory alloy (SMA) was subjected to tempering heat treatments meant to enhance the reversion to parent phase (austenite) of thermally induced martensite. By means of differential scanning calorimetry (DSC) the reversibility of martensitic transformation was verified during constant-rate heating-cooling cycles. The results have showed that 373 K- tempering destabilized martensite and enabled its
