Metal Joining, Forming Quiz-2

A : Forging and Rolling
In direct compression processes the force is applied to the surface of the workpiece and the metal flows at right angles to the direction of compression..

B : Close-die Forging
in closed die forgings the workpiece is deformed under high pressure in a closed cavity and thus precision forgings with closed dimensional tolenrances can be produced..

B : Dye penetrant test

D : both a and c
Physical method of powder production include Atomization and electrolytic deposition..

C : 2
Based on the recrystallization temperature manufacturing processes are classified into 2 types- hot working and cold working.

A : Warping
Distortion due to warp age is called warp defect. This may occur in castings that liberate residual stresses.

A : Warping
Distortion due to warp age is called warp defect. This may occur in castings that liberate residual stresses.

D : all of the above
Powder metallurgy (PM) is a term covering a wide range of ways in which materials or components are made from metal powder..

C : bloom
Bloom is the product of the first breakdown of the ingot during rolling.Further reduction by hot rolling results in a billet.

B : indirect extrusion
In indirect extrusion the ram containing the die is kept stationary, and the container with the billet is caused to move..
