1.10.2 Suitable alloys and their mechanical properties<br />

Requirements for alloys suitable for semi-solid forming:<br />

The metal can be brought homogeneously to a liquid fraction between 40 and 60%<br />

(i.e. no pure metal or eutectic alloy),<br />

The solid phase is prone to build a fine globular structure,<br />

The flow behaviour of the alloy is good.<br />

Static mechanical properties of AlSi7Mg0.3 (most used aluminium alloy) in various<br />

temper conditions<br />
