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.

Vehicles begin to arrive at a parking lot at 7:45 A.M. at a constant rate of 4 veh/min and continue to arrive at that rate throughout the day. The parking lot opens at 8:00 A.M. and vehicles are processed at a constant rate of one vehicle every 10 seconds. Assuming D/D/1 queuing, what is the longest queue, the queue at 8:15 A.M., and the average delay per vehicle from 7:45 A.M. until the queue clears?
