- Applicati, diagrammatique & Thermodynamique Métallurgique, The standard enthalpies of formation of intermetallic compounds of some late 4d and 5d transition metals have been measured by high temperature, direct synthesis calorimetry at 1373 ± 2 K. The following results in kJ/mol of atoms are reported: NbMn2 (−10.4 ± 2.7); NbRu (−0.7 ± 2.8); RhMo (−4.8 ± 1.8); PdMn (−45.2 ± 2.2); Pd2Mo (−9.2 ± 1.9); TaMn2 (−14.5 ± 2.5); IrMn3 (−13.2 ± 2.8); Pt3Cr (−8.8 ±, The intermetallic compounds of the Al-Ti system were investigated by direct reaction calorimetry at high temperatures. (b) Relative to solid Al (f.c.c.) Open image in new window, The wettability between silicon carbide and aluminum is poor, silicon carbide is difficult to fuse or the distribution of silicon carbide is not uniform in the ingot when the SiCp / 7075 composite is prepared by melt casting.The surface modification of SiCp by nickel plating can significantly reduce the wetting angle of SiC/Al and improve the distribution uniformity of silicon carbide in SiCp / 7075. This, work constitutes a part of a general study of the Al–Ni–Ti, ternary system. The as-cast ribbons of both compositions exhibited three-stage crystallization behavior. Herefore unpublished enthalpy data which were used in the derivation of smooth enthalpy and heat-capacity data for NBS SRM (Standard Reference Material) 720 ( alpha //2O//3, heat capacity and enthalpy standard) are presented along with some details of the high-temperature experiments.

X-ray powder diffraction and electron probe microanalysis were used to check structural state and stoichiometry of each phase. 6 publications. Average coefficient of friction for Al86Ni8Y6 and Al86Ni6Y4.5Co2La1.5 bulk samples at 3 mN were 0.36 and 0.32, which increased to 0.43 and 0.45, respectively, at 200 mN, attributed to the increase in the lateral ... DFT has been used extensively for predicting structural, physical, and chemical properties of aluminum alloys and intermetallic compounds. Please reconnect. On substituting nickel for copper the value of the heat of formation decreases over the whole range of homogeneity. ], Investigation of the thermodynamic properties of Ni-AI intermetallic compounds by an EMF method, Enthalpy and Heat-Capacity Standard Reference Material: Synthetic Sapphire (Alpha-Al2O3) From 10 to 2250 K, The Al-Ni-Ti system (Aluminum-Nickel-Titanium), The heats of formation in the system aluminium + nickel + titanium, An X-Ray Analysis of the Nickel-Aluminium System, Entanglement and quantum correlations in optomechanics. 1.79 lm3, which decreased to 0.78 and 0.5 lm3, respectively, in the corresponding consolidated samples. It is established, that the introduction of iron into the (Ni0.5Al0.5)β composition leads to increase in ΔHf,298°. The calorimeter measures a quantity, of heat, which can be considered as the sum of two contri-, As the heat contents of pure metals are tabulated, the enthalpy of formation at the calorimeter temperature is, readily deduced. Journal of Nuclear Science and Technology, Your Mendeley pairing has expired. used to check the crystal structure and the homogeneity of the calorimetric products. For bcc and fcc phases, Ni0.75Al0.25 and Ni0.25Al0.75 are predicted to be ductile behavior, while Ni0.5Al0.5 exhibit brittleness. The The heat of the formation of (Ni,Cu)//1// minus //xAl//x was measured at 1100 K as a function of concentration in the range of x//A//l equals 0. Bruno Brunetti, Vincenzo Piacente and Paolo Scardala . The chemical compositions were determined, microprobe (Service Commun de Microanalyse, Université, Henri Poincaré, Nancy 1, France). The Al–Ni system has been intensively studied both experimentally and theoretically. Enthalpies of formation for an average temperature of 548 K. have used the partial enthalpies of Ni and Al found by, in determining their enthalpy values. formally request permission using Copyright Clearance Center.

phases have similar enthalpies of formation: and the tight-binding theory of Pasturel et al. The experimental results show that there was a transition zone composed of four layers of Ti-Al compounds at the interface. Zn also has the potential to enhance the ductility of Al-Zr alloy by increasing work hardening through reduction of the alloy stacking fault energy.
