xopeaceoutt Posted February 24, 2009 Share Posted February 24, 2009 (edited) Is brass a substitutional or interstital alloy? Substitutional alloys have same sized components. Interstital include small atoms fitting into space b/w large atoms. like steel... But for the alloy for brass, would I have to uncover the size of the copper and zinc in order to see whether they are interstital or substitutional Edited February 24, 2009 by xopeaceoutt Link to comment Share on other sites More sharing options...

xopeaceoutt Posted February 24, 2009 Author Share Posted February 24, 2009 Thanks for the chart! I think it might be substitutional because of the relative sizes of copper and zinc. Link to comment Share on other sites More sharing options...
UC Posted February 24, 2009 Share Posted February 24, 2009 Correct The whole top row of transition metals, as you can see, are about the same size and many substitutional alloys are known between them. For example stainless steel is mostly iron, nickel, and chromium. Carbon is tiny by comparison, but has it's place in stainless steel as well, filling in some of the gaps between the Fe, Cr, and Ni.
