You are an officer in the Western-America Blacksmith Association, and you have determined that a number of your members would like to have a modern equivalent of an 1870-vintage blacksmith anvil. Your objective is to replicate the design, but utilize the advantageous features of today's engineering materials. You hope ultimately to identify a producer who will make a limited number of these items for sale and distribution through your monthly magazine. The proposed design is a large forging anvil that has a total length of 20 inches. The top surfaces must be resistant to wear, deformation, and chipping.
Estimated mechanical properties call for a yield strength in excess of 70 ksi, an elongation greater than 2%, and a Brinell hardness of 200 or more on the top surface. You feel confident that you will be able to secure a minimum of 500 orders.
1. Discuss the various properties that this part must possess to adequately perform its intended task.
2. Discuss the various concerns that would influence the proposed method of fabricating the anvils.
3. Assuming that the anvils will be made from some form of ferrous metal, consider the properties of the various types of cast irons and steels with regard to this application. Which material would you recommend? Why?
4. How would you propose that a production run of 500 replica anvils be produced?
