Test: Forming Processes - 1 - Question 1

Consider the following stresses:
1. Tensile stress
2. Compressive stress
3. Shear stress
In forming processes, metals are subjected to 

Test: Forming Processes - 1 - Question 2

Sheet metal operations are:
1. Hot working operations
2. Cold working operations 3
. Warm working operations
Which of the above is/are essentially true?

Test: Forming Processes - 1 - Question 3

Warm metal working is applied extensively for

Detailed Solution: Question 3

Warm working is the plastic deformation of a metal attemepratures below the recrystallization temperature range and above room temperature. It attempts to combine the advantages of both hot and cold working into one operation. Warm metal working has been applied most extensively to the forging of steel, where it offers the potential of fewer forging steps, reduced forging loads, and energy savings compared to cold forging.

Test: Forming Processes - 1 - Question 4

In which of the following process, a small-diameter thick ring is expanded into a large diameter thinner ring by placing the ring between two rolls

Test: Forming Processes - 1 - Question 5

Thick-walled seamless tube is produced by

Detailed Solution: Question 5

Rotary tube piercing is used to make long, thick- walled seamless tube. This process is also known as Mannesmann process. It is based on the principle that when a round bar is subjected to radial compression, a cavity begins to form at the center of the rod.
