Research on semi-solid slurry of a hypoeutectic Al-Si alloy prepared by low superheat pouring and weak electromagnetic stirring

Metallurgical structure of A356 aluminum alloy solidified under mechanical vibration: An investigation of alternative semi-solid casting routes

“…Many new techniques have been developed for creating semisolid structures since the inception of semi-solid processing; for example, electromagnetic stirring [7], ultrasonic vibration [8,9], low temperature casting [10], and gas bubble purging [11]. In this study, A356 aluminum alloy was studied because of its wide variety of applications and because its chemical composition is far below the Al-Si eutectic composition, meaning it has a wide solidification range suitable for semi-solid processing.…”

Effect of Process Parameters on the Microstructure of Semi-solid ZL101 Aluminum Alloy

“…The process depends on material behaving in a thixotropic way in semi-solid state [1][2][3][4] . The required spheroidal microstructure can be obtained by a number of routes, such as mechanical stirring 5,6 , electromagnetic stirring 7,8 . However, the former readily pollutes metal and the latter has low electromagnetic stirring efficiency.…”

Preparation of semi-solid AlSi7Mg alloy slurry with big capability

“…Meanwhile, an ideal microstructure of the semi-solid alloy slurry can be obtained. More attention has been given to semi-solid AlSi7Mg alloy slurries with small capability during the previous research study [14][15][16][17], and the mass of the prepared slurry is about 1.5-2.6 kg every time, which satisfies the production requirement of smaller rheo-forming parts. In practical application, however, bigger rheo-forming parts are needed to some extent.…”
