Material having a high electrical resistance and should not be used as conductor of electrical current.

Steel is heated to a temperature above the critical range, after which it is cooled in still air to produce a generally fine pearlite structure. The purpose is to promote uniformity of structure and properties after a hot-working operation such as forging or extrusion. What was the heat treatment involved?

Identify:

It is a process that produces residual compressive stress on the machine part, which uses a series of hammer blows on the surface.

(a)  

Weld spatter refers to:

Water should be run at a speed of

Galvanized steel plate is a plate coated with:

(a)  

It has been said that 80% of the failures of machine parts have been:

In laminated springs, the strips are provided in different lengths for:

Occurs when the oil film fails, but in this case, the load and speed are so high that the surface metal is melted and the metal is smeared down the profile.
