Conclusions
-
1.
The long-term strength of alloy D16 in the polygonized condition is higher than in the recrystallized condition after natural aging for as long as 2000 h and after artificial aging (at 190° for 8 h) for as long as 100 h.
-
2.
With identical aging conditions the rate of weakening is higher for polygonized samples than for recrystallized samples.
-
3.
After artificial aging the rate of weakening of the polygonized alloy is lower than after natural aging.
-
4.
The creep resistance of the recrystallized structure is higher than that of the polygonized structure.
-
5.
Decomposition of the solid solution occurs at a higher rate in the polygonized condition than in the recrystallized condition.
