“…Subsequently, the temperature of the melt was brought down to the semi-solid state (600-650°C) [21] and later, alumina nanoparticulate, preheated to 300 • C, enclosed in small packets of aluminum foil was directly immersed in molten metal with continuous stirring for one minute, using powered stir casting equipment at a constant stirring speed of 1000 rpm. The melt containing Al-12Si (wt.%) alloy reinforced with alumina nanoparticulate was transferred into the metal mould suspended at one end of the arm and the arm was rotated at 300rpm [22]. For each sample, 250gms of material was cast to get a solid cylinder-shaped specimen of 40mm diameter and 50mm altitude and cast specimens with 0.5, 1 and 1.5wt.% addition of alumina nanoparticulate were prepared using centrifuge casting technique.…”

The current research work discusses the concept of reinforcing alumina nanoparticulate to Al-12Si (wt.%) alloy using a unique casting technique known as centrifuge casting system established in-house at our advanced manufacturing centre. The resulting cast solid cylindrical specimen will be functionally graded along the length of the specimen containing higher percentage of primary silicon and alumina nanoparticulate at the top region than the bottom region, with a gradual transition in between the two regions. The microstructure of the functionally graded Al-12Si (wt.%) alloy, reinforced with 0.5, 1 and 1.5wt.% of alumina nanoparticulate was analysed using “Scanning Electron Microscope (SEM)” and the elemental composition of the cast specimens were obtained using “Energy-dispersive X-ray analysis (EDX)”. The outcomes of the EDX analysis confirmed the presence of alumina nanoparticulate in the cast specimens. Further, the mechanical properties of the cast Al-12Si (wt.%) alloy, reinforced with alumina nanoparticulate were studied, and it was found that the specimen with the addition of alumina nanoparticulate showed enhanced mechanical properties when compared with the Al-12Si (wt.%) alloy, without alumina nanoparticulate addition, cast under identical conditions.

“…X-ray diffraction analysis, referred to as XRD [ 20 ], is an analytical method to measure the internal atomic structure of the object to be measured by X-ray, which can be used for qualitative and quantitative analysis of the material. The DX-2700BH X-ray diffractometer produced by Dandong Haoyuan Instrument Co., Ltd. (Dandong, China) was used to analyze and characterize the phase of composites.…”

Synthetic diamond particle-reinforced copper-iron composites (SD/Cu-Fe) were produced by the powder metallurgical method for stone cutting applications, and the microstructure, density, compactness, hardness, flexure strength, and wear resistance of the composites were characterized in this work. The results showed that the diamond particles were relatively uniformly distributed in most areas of the copper matrix and the crystal shape of diamond particles were relatively intact in the sintering temperature range from 740 °C to 780 °C. The interfaces between the diamond particles and copper matrix, as well as the interfaces between the copper matrix and iron layer, were well bonded without significant gaps. The physical properties of composites increased first and then decreased with the sintering temperature. When the sintering temperature was 770 °C, the related properties reached the best. Diamond played a key role in improving the properties of the SD/Cu-Fe sandwich composite. This work provides a basis for the research and development of high-performance diamond-reinforced copper-based iron sandwich composites.
