“…By adding Strontium (Sr) as reinforcement in A356, the conversion of dendric microstructure into non-dendric at 625°C resulted in using liquidus casting for unmodified as well as modified (eutectic) A356 [61]. At the time of eutectic reaction, the undercooling temperature is lower down as compared to base alloy when 5% TiB2 is used as reinforcement in A356 [5]. In microstructure shape factor and circular diameter reduces as pouring temperature lower down.…”

“…The two or more materials namely "Matrix" and "Reinforcement" having different physical and chemical properties when mixed in a way that neither they fully fuse nor liquefy into one another, so despite they act jointly but remain dispersed are called composite [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Composites are mainly categorized into three groups as 1) Ceramic Matrix Composites (CMCs), a subgroup that consists of ceramic matrix and ceramic fibers [19][20][21][22][23][24][25][26].…”

Commercialization of the developed technology is a prime factor for any nation and sector to retain its existence in this global economy. Day by day the technological advancement touching new high in various sectors like the automobile and aircraft industries but high design efficiency is achieved only when it is complemented by appropriate material. In the list newer addition is MMCs (Metal Matrix Composites) which are favorable because of their lower cost achieved by cheaper reinforcement, easy processing, and capabilities of mass production. In recent days, the importance of semi-solid casting has been well accepted among various processing routes for aluminum alloys despite many challenges in terms of process parameters like porosity, agglomeration, non-uniform reinforcement particle distribution, low wettability, and engulfment, and this is a main consideration for the present work. Semi-solid casting is considered to be one of the most important and effective manufacturing processes of aluminum alloy for viable mechanical and metallurgical properties in the current perspective of product requirement and competitiveness. A glimpse of the current status is presented, which shows the potential of the process which can be utilized by the industries for several benefits. In a nutshell, it can be found that process has the capability of alteration by the use of different scraps and also have flexibility according to the processing parameters like stirring, pouring temperature, type of reinforcements, etc.

“…[1] It is well known that air entrapment formed in the HPDC process may result in blistering at around 540 °C. [2,3] This restricts conventional solution heat treatment for dissolving coarse eutectic Si phase and homogenization of the casting, resulting in low ductility of HPDC alloy. Many attempts have been devoted to refining the coarse eutectic silicon to several microns, i.e., adding chemical elements of Sr or Na to Al-Si alloy to modify the Si microstructure and enhance the ductility.…”

The microstructure, mechanical properties, and thermal stability of high‐pressure die casting (HPDC) Al–12Si–Sc alloy with 0.1 wt% Sc addition are investigated. Compared with the commercial A380 alloy, the alloy shows a significant refinement of α‐Al and eutectic Si microstructure. Meanwhile, β‐Fe with irregular morphology shows a smaller size and lower volume fraction in Al–12Si–Sc alloy. Upon as‐cast state, the elongation of the alloy is improved to 6.7% with an ultimate tensile strength of 332 MPa, which is a better combination of ductility and strength in the literature. After thermal exposure at 200 °C for 200 h, it retains tensile strength of 277 MPa and holds the microhardness up to 90 HV even exposure for 1000 h. These excellent properties may widen the application of HPDC Al–Si alloy for the cylinder block and cylinder head.
