  • Processes for producing Mg-based composite materials
    Patent number: 5791397
    Abstract: The present invention relates to a process for producing a Mg-based composite material by using Mg or a Mg alloy as the matrix and utilizing a spontaneous infiltration phenomenon. This process comprises the step of bringing a powder mixture composed of a reinforcing agent and a infiltration agent into contact with a molten matrix metal comprising Mg or a Mg alloy, so as to cause the molten matrix metal to infiltrate into the powder mixture. The present invention also relates to a process for producing a Mg-based composite material which comprises the steps of forming a preform composed of a reinforcing agent and a infiltration agent and causing a molten matrix metal comprising Mg or a Mg alloy to infiltrate into the preform.
