Chapter 4, Problem 1.1CS
Consider the manufacture of a fishhook beginning with 1080 steel wire. What forming operations would you want to perform before subjecting the material to a quench�and�temper hardening operation? Would it be best to sharpen the point before or after hardening? Would your answer be different if you were to sharpen by chemical removal instead of

What is the hardening process? What is rooting?
Heat treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. When performing the cooling step of the tempering process, knife makers have used material such as clay to cover portions of the blade to slow the cooling rate of the covered steel. Why may this technique be beneficial for making a sword which holds a sharp edge while remaining flexible enough to withstand the forces subjected to it in battle?
Q3 Give the reason for 10 of the following. -
1- The use of lubricant in wire drawing die.
2- The uses of tungsten carbide for the manufacturing of die tool.
3- The increase of Mo/Si ratio during the production of white cast iron.
4- The addition of Al to copper alloys.
5- Aluminum is a better overall conductor than Copper for long distance electric
transformation.
6- The addition of cryolite in smelting electrical furnace due to the production of
aluminum.
7- The addition of Magnesium and Cerium during the production of Ductile cast iron.
8- The addition of 13% Cr to steel in corrosive environment.
9- The increase of hardness for chips due to the cutting process.
10- The brittle fracture of steel at low temperature lower than -4 C.
11- The heating of metal after the rolling process.
