Abstract

Three kinds of process properties

such as filling ability

sensibility of cracking and feeding ability

were presented in view of the familiar defects in squeeze casting process or molten metal die forging process（MMDF

for short）.Moreover

their characterization parameters were defined quantificationally as maximum filling length

staying time in molds and effective feeding length

respectively.Some experiment methods and equipment were suggested to experimentally determine their values.It was pointed out that those process properties were controlled mainly by the alloy properties

die types and the forge processing parameters.
