Heat capacities have been determined for unsupported aluminum clusters, Al49(+) - Al63(+), from 150 to 1050 K. Peaks in the heat capacities due to melting occur between 450 and 650 K (well below the bulk melting point of 933 K). The peaks for Al+51 and Al+52 are bimodal, suggesting the presence of a premelting transition where the surface of the clusters melts around 100 K before the core. For ...

Recently, Wang et al. discussed the properties of fuzzy information systems under homomorphisms in the paper [C. Wang, D. Chen, L. Zhu, Homomorphisms between fuzzy information systems, Applied Mathematics Letters 22 (2009) 1045-1050], where homomorphisms are based upon the concepts of consistent functions and fuzzy relation mappings. In this paper, we classify consistent functions as predecesso...

Flame Thermal Spray technique was used to produce matrix composite of ZrO2 (25%) reinforced with Alumina (Al-Ni) (50)% have been spray into base substrate stainless steel type (316L). All samples were grit blasted as initial preparation state and all spraying done at different distances from (12, 14, 16,17, 18, 20) cmtest stiffness, porosity adhesion has experienced on the compound layer which ...

Abstract FeCoNiCu 0.4 Al high entropy alloy (HEA) were produced via mechanically alloyed (MA) and spark plasma sintering (SPS) at 950~1100 °C. Microstructure mechanical properties of bulk HEA are studied. In the process temperatures ≤1050 °C, disordered FCC phase precipitates BCC phase. When temperature increases to 1100 only single could be clearly detected. The stability is obviously influenc...
