Abstract
An extrudable and weldable matrix alloy composite comprising: a) a base material metal of about 50 to 99.9% by weight, b) boron carbide or silicon carbide of about 0.1 to 50% by weight, c) less than about 3.0% by weight of at least one metal having an intermetallic phase temperature lower than the melting point of the base material metal, and d) a reinforcement agent of up to about 5% by weight.
Claims30
An extrudable and weldable matrix alloy composite comprising:
- a) a base material metal of about 50 to 99.9% by weight,
- b) boron carbide of about 0.1 to 50% by weight, the boron carbide being substantially homogeneously distributed among the metal, forming close grain boundaries therewith;
- and
- c) less than about 3.0% by weight of at least one metal having an intermetallic phase temperature lower than the melting point of the base material metal, the metal being included with the boron carbide during its production to provide a chelating opportunity for the base material metal.
