, As a material is heated Energy is added to the structure, the atoms move further apart, the atoms vibrate
more vigorously, the metal expands
The state of matter that exhibits the least amount of energy Solid
is:
A problem occurring in weldments caused by the non- Distortion
uniform heating produced by the welding operation is:
What are some methods used to reduce or eliminate Vibratory stress relief, thermal stress relief, peening, annealing
residual stress?
The type of alloying in which the alloy atoms are located in interstitial alloying
the spaces between the atoms of the parent metal is
referred to as:
Rapid quenching of a steel from the austenitic range Martensite
results in a hard, brittle structure as:
Very slow cooling of steel may result in the production of a Pearlite
soft, ductile microstructure which as a lamellar appearance
when viewed under high
magnification. This structure is referred to as:
When rapid cooling produces a martensitic structure, what Tempering
sub-critical heat treatment may be applied to improve the
ductility of the steel?
It is determined that a welding procedure is creating an Decrease voltage and current, increase travel speed, switch from weave to stringer
excessive heat Input. Which of the changes listed below beads
would result in a reduction of the
heat input?
The use of preheat will tend to: Wider HAZ, lower HAZ hardness, slow cooling rate, reduce tendency to produce
martensite in HAZ
What changes will warrant an addition or increase in the Increased carbon equivalent, increased base metal thickness
required preheat?
What heat treatment is characterized by holding the part at Annealing
the austenitizing temperature for some time and then slow
cooling in the
furnace?
What heat treatment is characterized by holding the part at Normalizing
the austenitizing temperature for some time and then
cooling in still air?
Steel heated above the lower transformation temperature 1333
(A1) will change microstructural alignment. This
temperature is:
