Abstract
Composite materials can be produced by PM means. If both components can be deformed, an atomic bond is formed between the new surfaces generated. The structure, properties, and technological applications of metal-glass composites are illustrated by the Al-glass system. The influence of the starting material and the deformation process on the properties is discussed. For the same starting material and production methods, the hardness, strength, and wear resistance can be increased in excess of those predicted by the law of mixtures, whereas the elastic modulus and physical properties essentially conform to this law. Once formed, the composite materials can be further hot worked, and cold worked to a limited extent. They can also be soldered and glued. It is possible to surface treat them, e.g. anodize or enamel.
