In this study fabrication conditions, microstructure, mechanical properties and corrosion resistance of pressureless sintered magnesium alloys containing boron and metals (Ti, Zr, Co, Si, Al) were investigated. These alloys were sintered at a temperature of 913-1023K in 1 atm argon. During the liquid sintering process of Mg alloys containing boron, MgB<SUB>2</SUB> particles were formed and dispersed in Mg matrix. Addition of boron and the formation of the boride improved the mechanical properties of Mg. And moreover, some metals (especially aluminum) improved the mechanical properties of Mg alloys containing boron. Especially, Mg-6vol%B alloy sintered at 1023K had a bending strength of 210MPa and the Rockwell hardness of 91HRH. Mg-6vol%Al-8vol%B alloy sintered at 1023K had a bending strength of 349MPa and the Rockwell hardness of 105HRH.
