Al lithium alloys

Question 1

in Al Li alloys what is the stesp to EQ phase

Answer 1

goes from a ssss to transition(Al3Li) to AlLi which is EQ phase.

Question 2

what does the transition phase from in the alloy

Answer 2

called the delta prime which is Al3Li, forms as rapidly spherically, coherent precipitate in binary Al-Li matrix.
➢ These precipitates are
homogeneously distributed
and impede movement of
dislocations during plastic
deformation, thereby
strengthening the alloy

Question 3

in Al-Li alloys qhat is used to break up intergranular precipitates and inhibit recrystallisation

Answer 3

Zr
