21. Highly purified zinc, at room temperature, is ductile . 22. Ductile iron quickly became popular for agricultural machinery, automotive parts and pipes.23. The metals are extremely corrosion-proof and ductile . 24. Ductile materials can sustain large plastic deformations without fracture.25. It has press-fitted, ductile iron liners. 26. If a material has high fracture toughness it will probably undergo ductile fracture. 27. Solid mercury is malleable and ductile and can be cut with a knife. 28. Related criteria distinguishing ductile from brittle failure behaviors have been derived and interpreted. 29. Too low an effective confining pressure may cause the cement to become ductile . 30. A highly ductile and malleable metal known as Zuunium can be found here.
