Semisolid melt solidification

Multiplication of the above-mentioned methods (l)-(3) by the number of possibilities to employ additional fields or treatments in order to control the solidification reaction gives approximately 25 known schemes for semisolid melt solidification with commonly used abbreviations (Tretyakov and Goodilin 2000). Method (1) includes the largest... 

The following common abbreviations of semisolid melt-solidification techniques (given in alphabetical order) are often used in the literature (for details, see, e.g., Shiohara and Endo 1997, Desgardin et al. 1999, Tretyakov and Goodilin 2000) CUSP Constant-Undercooling Solidification Processing often reported method...

A modification of melt stirring, termed compocasting (or rheocasting), is used to obtain a suitable slurry by employing powerful agitation of a semisolid (two phase) alloy to yield a non-dendritic phase, which imparts thixotropic properties. The mix is then infiltrated to produce a near net shape component [138-139]. It is desirable that the alloy has a wide solidification range in which it exists as a semisolid. The volume fraction of carbon fiber is restricted to about 20% to obtain effective dispersion.
