Solution:

In Powder Metallurgy, the strength of the green compact is achieved by:

Tempering

Compressed tempering

Sintering

None of the above

Solution:

The primary mode of deformation of the metal during spinning is

bending

stretching

rolling and stretching

bending and stretching

Solution:

The powder metallurgy process in which oil is permeated into the pores of the product is known as

Mixing

Sintering

Impregnation

Infiltration

Solution:

In the wire drawing process, the bright shining surface on the wire is obtained if one uses:

does not use a lubricant

uses a low-cost tooling

uses a thick paste lubricant

uses a thin fluid lubricant

Solution:

Hemming is a process in which the edge of the sheet is folded over itself. The purpose of hemming is to:

increase the stiffness of the part

improve appearance

eliminate sharp edges

Solution:

In the rolling process, how can the roll separating force be decreased?

Reducing the roll diameter

Increasing the roll diameter

Providing back-up rolls

Increasing the friction between the rolls and the metal

Solution:

Upset forging involves

none of the above

increasing the cross-section of a material at the expense of its length

decreasing the cross-section of a material at the extension of its length

reducing diameter of a rod by forcing it into a confining die
