In the Late Classic Period Yaxchilan was one of the most powerful Maya cities along the course of the Usumacinta, with Piedras Negras as its major rival. Architectural styles in subordinate sites in the Usumacinta region demonstrate clear differences that mark a clear boundary between the two kingdoms.
Answered by The Community. Making the world better, one answer at a time. Steel is not usually considered a composite, as it is macroscopically homogeneous. However, some steel types, including classical iron-carbon steel, can be considered as metal-matrix composites, as they contain a second phase... sometimes.
Best Answer: An alloy is a homogeneous mixture (solution) of two or more metals. A composite material is often heterogeneous, and is not always of metals. Example of Composite Material: Concrete and Fiberglass. It is material composed of more than one material, they are mixed but not in a homogeneous form. Example of Alloy: Steel and Copper. It is made of more than one material also, but they are well mixed, usually metals are melted and mixed together to give an alloy.
