Abstract
The production method of the near-net shape molded Mg-Ca-Zr alloys by the devised semi-solid squeeze casting was established and the fabrication factors for sound products were also investigated. The Mg-Ca-Zr alloys having an ignition-proof property and very fine spherical structure provide high production safety and good fluidity for quality near-net shape products in semi-solid state processing. The orifice with a diameter of 30 mm and a plunger speed of 80 mm/s contribute successfully to infiltrate the semi-solid state prema-terial into the designed mold perfectly within the limited infiltration time. The tensile strengths and elongations of the ignition-proof Mg-Ca-Zr and Mg-Zn-Ca-Zr alloys are improved by applying the high pressure of 100 MPa, indicating that pressure more than 100 MPa is also an important fabrication factor.
