INTRODUCTIONSemisolid metal (SSM) processing (also known as semisolid forming [SSF] or semisolid metallurgy) is a relatively new metal casting technology. The conventional metal-forming processes use either (1) metals in solid state (solid state forming) or (2) metals in liquid state (casting).

Thermodynamic Calculations of Aluminium Alloys for Semi-Solid Processing

SSM processing technology has made considerable advances since its initial discovery in 1973. Since 40 years ago, only few materials are used as thixoforming materials such as A319, A356, A357 and a small nuer of wrought alloys. Hence, there is a clear

Semi-Solid Metal Casting & Forging - BuntyLLC

Semi-solid metal casting requires the use of low-viscosity fluid (yet not molten) materials. Casting occurs at temperature ranges in which some 30% to 65% of the metal remains in a solid-state and 70% to 35% has become viscous. Semi-solid metal casting will occur at variable temperatures, based upon the composition of the alloys in use.
