    1. Alloy As composite is made of undissolved elements.

      Alloy

      As composite is made of undissolved elements.

      For sure steel is an alloy. If by the basic difference between a alloy and composite, we know that alloy must have a metal which acts as its parent component However the composite don't have a metal component. Both are mixtures of different components with different physical and chemical propertiesRead more

Both are mixtures of different components with different physical and chemical properties but alloys have a metal.

      Steel has Fe metal and other alloying elements and so it’s an alloy.

      Let us assume for sometime your answer is right then if make material with  metal matrix(Al) reinforced with carbon fiber(small volume fraction) then I should call it as alloy or composite?

      It's a composite. I understand I should have explained it properly and missed a point that composites can have metal matrix as base material. The main difference alongwith the composition lies in their formation and property. The alloys as steel has different properties than its main alloying elemenRead more

      It’s a composite.

      I understand I should have explained it properly and missed a point that composites can have metal matrix as base material.

      The main difference alongwith the composition lies in their formation and property. The alloys as steel has different properties than its main alloying elements (Fe is soft ductile initially but with C steel is harder stronger).

      However if you look in composite they retain their original properties as in Al and Carbon fibres the Al as base matrix and Carbon fibres reinforced, they can be distinguished. You can distinguish between Al and Fibres easily. However in steel you can’t say where is Fe and C properly.

      These are also some points which differ between alloy and composite.

      Feedback is welcomed.

      Well I didn't knew about ODS steel but found this. I think this well suits my explanation, look in the process of its formation, we process it in a way to produce homogeneous solid solution. Also composite are heterogeneous mixing.

      Steel is alloy. Composite is made when in one matrix other elements are present in undissolved form which provides strength.

      Steel is an alloy. Alloy is mixture of two or more elements in which one must be a metal. Composite also mixture of two or more elements but it doesn't have any metal. Steel is a mixture of iron and carbon and it may contains tungsten chromium and some other elements also. But it is mainly consistsRead more

Steel is a mixture of iron and carbon and it may contains tungsten chromium and some other elements also. But it is mainly consists of iron and carbon. And iron is a metal. So steel is an alloy.
