Question
Chapter 13, Problem 1CQ
To determine
The temperature at which the metal is deformed in hot work.
Expert Solution & Answer
Answer to Problem 1CQ
In hot-work, a metal is deformed at temperature that are either aboverecrystallizationor above 50% of the above absolute melting temperature.
Explanation of Solution
The processs of recrystallization happen during the hot working metals. It undergoes plastic deformation. The recrstallixation temperature is very high at which the rate of growth of new grain is accelerated and finally the metal consistsonly one grain.
The hot working operation are done in many stages. Recrysatllization is first step at which the metal is heated, and then follows the intermediate step and finally finishing step. The process does not produce any strain hardening, and that’s why there are no increse in yield strength and hardness. The ductility of final metal is high.
Thus, in hot-work, a metal is deformed at temperature that are either above recrystallization or above 50% of the above absolute melting temperature.

Fluid enters the suction line from reservoir 1 (left) through a sharp-edged inlet. The suction line is 10 cm commercial steel pipe, 15 m long. Flow passes through a pump with efficiency of 76%. Flow is discharged from the pump into a 5 cm line, through a fully open globe valve and a standard smooth threaded 90° elbow before reaching a long, straight discharge line. The discharge line is 5 cm commercial steel pipe, 200 m long. Flow then passes a second standard smooth threaded 90° elbow before discharging through a sharp-edged exit to reservoir 2 (right). Pipe lengths between the pump and valve, and connecting the second elbow to the exit are negligibly short compared to the suction and discharge lines. Volumes of reservoirs 1 and 2 are large compared to volumes extracted or supplied by the suction and discharge lines. Calculate the power that must be supplied to the…arrow_forward
