I want to know what are the methods of adding powders (for example SiC) to melt ( Al ) for fabricate composites in semi solid processing?
The papers below review some mixing methods, and they can also help you further on other issues that may arise:

one of the methods , inject the powders with argon gas into the melt .

because of the metal quantity should be 30 to 65% solid in mentioned method. you must chose the hypoeutectic composition as main raw materials.In this method, Vortex method introduced as common procedure.
Hi, thanks alot for your attention, but i think you don't understand my question,i don't want to know semi solid processing.I want to know what method or methods is that i can add the powders in melt .but i made a mistake in expressing the question.
i'm very sorry.
Hi.
Please follow the Vortex method. Please pay attention, using to flax can protect melting as anti-oxidation
Please find article;

I think you have a lot of way to do it! but first of all, it is necessary to indicate your devices and or method of casting or semisolid casting!?? As mentioned in last answer Vortex method or Ultrasonic agitation or electromagnetic mixing could be helpful. Generally, the mechanical methods are clunky with shortcomings so it is better to choose your method from innovative process.
