Fig. 2--Microstructure of wrought Armco iron showing grain growth caused by thermal cycling: (a) as-received, (b) after 3 thermal cycles, and (c) after 10 thermal cycles9
and a few small isolated grains within those large grains (Figure 2); no triple or quadruple points remained. In much larger specimens, triple and quadruple points would be present even with large grains and the alpha-to-gamma transformation could then start at temperatures lower than 911 ~ REFERENCES 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32.
