“…Therefore, the experimental results show that the microstructural evolution depends on the chemical composition for all alloy systems. Similar microstructural evolution has been observed for Ni-xSi (x = 5, 10, 15 and 20) alloys by Karakose and Keskin [12] and for Ni-xSi (x = 10, 21.4, 25 and 35) alloys by Çadırlı et al [15]. Fig.…”

“…Similar to that of the annealing temperature effect examined by the X-ray and SEM micrograph shape indicate the change of microstructure from coarse dendrites to lamellar morphology. However, similar effects due to annealing temperature are reported for the alloy systems of (Al-Ni x ) (9) and (Al-Ni-xSi) (10), (11) . Moreover, in DTA analysis curve has been obtained three peaks of endothermic reactions, were these indications are agreeing with the results obtained by XRD and SEM techniques.…”

Introduction: The Al 85-Ni15 alloy with 99.99% purity of Al and Ni were prepared by an arc melting technique system. The annealing effect onthe microstructure properties, phase transformation and micro-hardness for the Al-Ni alloy system were investigated. Material and Methods:The alloys were characterized by X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Differential Thermal Analysis (DTA) as well as Vickers micro-hardness measurement. Results and Discussion: The quantitative results confirm that the chemical composition of the alloys is very close to compositions and the microstructures are in typical lamellar morphology. Mechanical properties for the as-prepared samples and subsequently heat-treated samples were measured by a Vickers indenter. Values of the micro-hardness (HV) Conclusions: According the XRD pattern analysis a multi phases produced, such as Al, AlNi3in room temperature, Al3Ni2, Al0.42Ni0.58 at 200ºC, Al1.1Ni0.9 at 300ºC and Al 0.802Ni0.198, AlNi3 and AlNi at 400ºC, and Al0.802Ni0.198, AlNi3 and AlNi for 500ºC. Similar approached were obtained from the results of SEM and DTA measurements. Annealing treatments are visibly affecting the alloy phase formation with different phases at different temperature. and the elastic modulus (E) of the as prepared sample are 132.9±0.1 kgfmm-2 (1.329±0.1 GPa) and 80.340±0.1 GPa, respectively. Furthermore, the characteristic of the materials plasticity (δH) value was calculated to be 0.85. The micro-hardness values are decrease with the increase of annealing temperatures.

“…Superior performance of the alloy is directly correlated with its microstructural evolution. Microstructural evolution in undercooled pure metals and alloys has attracted great interest for several decades [2][3][4][5][6][7]. One of the important outcomes of moderate undercooling experiments is the observation of "a refined grain microstructure".…”
