Abstract
Magnesium forms 2% in the earth's crust, magnesium is widely used in industry. For example, industrial machinery and electronics, and many developed in the field of biomedicine, especially in the field of orthopedics. Magnesium about 60% is present in the human bones, therefore it has great potential for human body implants. However, it is necessary to increase themechanical and chemical properties of magnesium in order to be used for bone implant materials. Production process using squeeze casting method. Through this method, Liquid metal is given hydraulic pressure, so the mechanical properties of magnesium werebetter. In this research use temperature parameter = 450 ̊C, pressure = 300 MPa, duration of press 1 minute and variation of holding time 7 and 9 minutes. Magnesium AZ31 increased compared with samples without treatment. Tensile strength with holding time 7 minutes equal to120.27 MPa, holding time 9 minutes was 128.77 MPa, and samples without treatment of was 94.63 MPa. The magnesium hardness value of AZ31 decreased at 7 minute detention was 39 VHN, compared with the sample without treatment of was 41.8VHN. And the hardness value increased at holding time 9 minutes equal to 46.2 VHN. However, it should be noted that excessive overheating and holding time may lead to decrease in magnesium mechanical properties of AZ31.Keywords: Magnesium AZ31, Squeeze Casting, Holding Time, Biomaterial, Mechanical Properties
