“…Compared to SEED and GISS methods, RSF exhibits low sensitivity to temperature, as well as fast cooling facilitated by enthalpy exchange in a short period. Sharma et al [15] reported that under various conditions of grain refinement and modification, an increase in holding time of slurry resulted in larger and more spherical α-Al grains, while hardness decreases for the investigated A356 alloy. Östklint et al [16] investigated the correlations between Al addition levels and grain size/solid fraction of Mg-Al alloys prepared with RSF method.…”

Mass reduction for automotive components has become one of the key approaches for greenhouse gas emission reduction of the automotive industry [1] . Materials selection, tooling design, and processing parameters are the three crucial pillars for achieving mass reduction in automotive castings [2] . Gravity casting and low pressure die casting processes have a relatively longer cycle time, and hence higher manufacturing cost for high volume production. Traditional high pressure die casting (HPDC) process has a much shorter cycle time, which is suitable for scaled production in the automotive industry [3] . However, some casting defects, such as gas porosities and shrinkage porosities in HPDC components, cannot be

A self-healing non-ferrous metal-matrix composite is prepared by the high-pressure die-casting process. It includes casting set-up, sample preparation of metal matrix composite (MMC), microstructural characterization, and analysis of its ability to close the crack. Aluminum alloy (A356) is deployed as a matrix material in the MMC. Nitinol is a smart alloy produced by a combination of Nickel and Titanium in equal mass proportion. Apart from excellent mechanical properties it also exhibits super-elasticity and shape-memory effect. The wire of the Nitinol is integrated as reinforcement within the matrix of A356 alloy through a high-pressure die-casting process. The recovery percentage of the metal matrix composite and microstructural evaluation are reported. The deployment of shape memory wire provides the ability to recover the matrix material even from plastic strain by just heating the sample slightly above the activation temperature of the Nitinol wire. Microstructural evaluation indicates fair integration of the reinforcement within the matrix material. Gaining the ability for 30.27% angular restoration and 19.37% crack closer is a very positive sign for designing self-healing metallic materials.
