A
alpha cementite
6
Q
where does proeutectoid exist??
A
above and below the eutectoid point
7
Q
how do you form martensite?
A
rapidly cool
8
Q
annealing is?
A
relieving material stresses
9
Q
Is plain carbon low or high alloy?
A
plain carbon = low alloy
10
Q
what is ‘wrought’
A
the alloy has been worked
11
Q
what is casting?
A
the alloy is poured as a liquid into a near finished form (more brittle)
