Answer:

The creep temperature for different materials is as follows.

A. Nickel :-
T_(c) = 690.4 K

B. Copper :-
T_(c) = 542.8 K

C. Iron :-
T_(c) = 723.6 K

D. Tungsten :-
T_(c) = 1469.2 K

E. Lead :-
T_(c) = 240.2 K

F. Aluminium :-
T_(c) = 373.2 K

Step-by-step explanation:

Creep is the slow plastic deformation occur at high elevated temperature.

The approximate temperature for different metals is as follows at which creep becomes considerable.

A. Nickel :- The relation between melting temperature & creep temperature is given by the formula.


T_(c) = 0.4 T_(m)

The melting temperature of nickel = 1726 K

Creep temperature
T_(c) = 0.4 × 1726


T_(c) = 690.4 K

B. Copper :- The relation between melting temperature & creep temperature for copper is given by the formula.


T_(c) = 0.4 T_(m)

The melting temperature of copper = 1357 K

Creep temperature
T_(c) = 0.4 × 1357


T_(c) = 542.8 K

C. Iron :- The relation between melting temperature & creep temperature for iron is given by the formula


T_(c) = 0.4 T_(m)

The melting temperature of iron = 1809 K

Creep temperature
T_(c) = 0.4 × 1809


T_(c) = 723.6 K

D. Tungsten :- The relation between melting temperature & creep temperature for tungsten is given by the formula


T_(c) = 0.4 T_(m)

The melting temperature of iron = 3673 K

Creep temperature
T_(c) = 0.4 × 3673


T_(c) = 1469.2 K

E. Lead :-The relation between melting temperature & creep temperature for lead is given by the formula


T_(c) = 0.4 T_(m)

The melting temperature of lead = 600.5 K

Creep temperature
T_(c) = 0.4 × 600.5


T_(c) = 240.2 K

F. Aluminium :- The relation between melting temperature & creep temperature for aluminium is given by the formula


T_(c) = 0.4 T_(m)

The melting temperature of lead = 933 K

Creep temperature
T_(c) = 0.4 × 933


T_(c) = 373.2 K
