This work presents experimental analysis to determine the effect of sand and squeeze casting methods on the Tensile and Hardness properties of AA6063 Aluminium. Sand and squeeze cast moulds were fabricated and used to produce Aluminium rods. The test samples from cast rods were subjected to Tensile and Hardness tests. The results obtained showed better Tensile and Hardness properties, in the squeeze cast samples that were produced under varied pressure. The hardness of squeeze casting varied from 72.9 to 82.3Hv, while that of sand casting had 70.0Hv. Also, Ultimate Tensile Strength increased with increased pressure in squeeze castings from 178.01 to 194.04MPa and 161.97 in sand castings. Conversely, the mechanical properties of the cast products improved from those of sand casting to squeeze casting. Therefore, squeeze cast products could be used in as-cast condition in engineering applications requiring high quality parts while sand casting may be used in as-cast condition for non- engineering applications or engineering applications requiring less quality parts

A research program was simulated to study the effects of pouring temperature, squeeze pressure and die temperature on the tensile, elongation and hardness properties of AZ91D magnesium alloys using anycasting software. The curves with different processing parameters on mechanical properties have been painted. The results indicated that mechanical properties increased firstly, then decreased when the pouring temperature increased to 670°C, and gradually increased with the increasing of squeeze pressure. The affect laws of mould temperature are similar as ones of pouring temperature. Eventually found that the squeeze casting got better mechanical properties(σb= 225MPa, δ= 3.6%, Vickers hardness=62) on the pouring temperature 670°C, mold temperature 180°C, holding pressure 120Mpa, pressure duration 25s.

AlSiMg (A357) composites containing 10 vol. % zirconia (ZrO2) particulates have been synthesized by the stir process followed by squeeze casting. Pressures of 25 and 50 MPa were maintained during solidification in specially designed die and ram and maintained at 250°C. Results show that with increasing squeeze pressure, the density increases while porosity decreases. The hardness of squeeze cast composite is higher than that of stir casting by about 10%. The compression properties have been evaluated and compared. The results show that compressive strength increases with squeeze pressure.

Alloy 6061

Squeeze casting is a hybrid metal processing technique that combines the advantages of both casting and forging in one operation. The automotive and aerospace sectors are behind the development of squeeze casting process as the squeeze cast components exhibit improved mechanical properties. The Aluminium alloy 6061 is a futuristic material that is widely used to produce automotive and aerospace components. In this attempt, cylindrical components of AA6061 were produced by varying the squeeze pressure at certain levels when the die preheat temperature and the pressure applied duration were maintained at constant levels. The specimens were made from the components as per ASTM standards and they were tested for mechanical properties such as impact strength and micro hardness respectively. It was found that the mechanical properties were enhanced with the increase in squeeze pressure.

In this paper, the castings of A356 alloy were made by the rheo-squeeze casting with slurry-making from the process of LSPSF. Experiments were designed to study the influence of three parameters in rheo-squeeze casting process, such as injection speed, mould preheating temperature and injection pressure, on castings performance. The results show that high-quality castings were produced with the injection speed of 0.5m/s ,the mould preheating temperature of 240°C, the injection pressure of 50MPa. The mechanical properties, such as the yield strength, tensile strength and elongation of the castings with T6 heat treatment are 241 MPa, 328MPa and 11.6%, respectively.

Cast Condition

Semi-solid squeeze casting (SS-SC) is a new processing technology which combines semi-solid processing (SSP) and squeeze casting (SC). In this process, semi-solid slurry fills mold by using its rheological property and solidifies under high pressure. It has several advantages, such as stable filling, small heat impact to the mold, low cost, high density and excellent mechanical properties of castings, which receives more and more attention. The microstructure of castings provided by SS-SC is quite different from that of casting provided by conventional SC in as-cast condition, which leads to differences in the evolution of microstructure and mechanical properties in heat treatment process. In this study, A356.2 aluminum alloys castings were provided by both SS-SC and conventional SC respectively. The evolution of microstructure and mechanical properties of castings during heat treatment was investigated to obtain the best mechanical properties of semi-solid squeeze castings.

The microstructures and mechanical properties of T5 heat-treated Al - 5.0 wt % Cu - 0.6 wt % Mn alloys with different Fe content prepared by squeeze casting were studied by tensile test, optical microscopy (OM), scanning electron microscope (SEM) and electron probe micro-analyzer (EPMA). The results showed that the dominate Fe-rich intermetallics are α (CuFe) with a few Al3(FeMn),Al6(FeMn), and α-Fe in the alloys depending on different Fe content. With the increasing Fe content continually, the ultimate tensile strength and elongation of the alloys decreased gradually. This is attributed to the increasing amount of Fe-rich intermetallics, the decrease of precipitation particles in α (Al) matrix and the increase of α (Al) dendrite size. The elongation level of 13.7% was still obtained in the squeeze cast alloy even when the Fe content was as high as 1.5%.

Several rheocasting processes have been developed or applied in the world. One of the new rheocasting processes is the limited angular oscillation (LAO), in which the molten metal is rapidly cooled and slightly mixed during initial stages of solidification. Squeeze casting (SQC) using semi-solid slurry produced by LAO (Rheo-SQC) has been developed. Microstructure and mechanical properties of squeeze cast semi-solid slurries have been investigated. Complete parts with little defects have been produced. The ultimate tensile strength and elongation of semi-solid cast samples are higher than those of the liquid cast samples. It can be concluded that the rheo-SQC is a feasible process.

This paper mainly focusses on parametric optimization of squeeze cast AC2A Ni coatedSiCpcomposite through Taguchi technique. Composite samples have been cast through squeeze casting for each experimental trial based on L16 orthogonal array. From analysis of variance (ANOVA), it has been found that reinforcement percentage, squeeze pressure, and pressure duration were the casting parameters making significant improvement in the mechanical properties such as hardness and ultimate tensile strength. Reinforcement percentage and squeeze pressure have been identified as the most influencing parameters from the percentage contribution analysis. The optimum parametric setting has been determined through Taguchi technique. It has been confirmed that AC2A-Ni coatedSiCpcomposite obtained for the optimum parametric setting has exhibited better mechanical properties compared to the experimental trials.

The processing of large or near-net shaped parts from g-TiAl alloys is extremely challenging. The forging of large-scale TiAl-parts is hampered by the unavailability of high-quality, chemical homogenous pre-material. However, using an innovative combination of forging and joining large discs of TiAl with excellent mechanical properties can be produced. Metal Injection Moulding (MIM) facilitates the production of near-net shaped parts of high-strength TiAl-alloys with strength comparable to the cast condition.
