Excerpt from The Iron and Steel Magazine, Vol. 7: Successor to the Metallographist; A Monthly Publication Devoted to the Iron and Steel Industry; January to June, 1904 There is no doubt that the comparatively soft metal iron in itself would be of little service to the world at the present day in face of requirements which necessitate a material possessing resistance to much greater stresses and wear and tear than form erly. Professor T. Turner has shown that the pure metal iron is not considerably harder than copper, nor is it very much stronger as regards tensile strength. It can, therefore, be readily imagined how in itself such a metal would render impossible that combination of high speed with greater wear and tear for uses which are the result of modern mechanical progress of all classes. Without doubt, further developments will largely depend upon the material which the Metallurgist can offer for utilization by the civil, mining, mechanical, or electrical engineer.
