21. Hardness is dependent on ductility , strength, toughness, viscoelasticity, and viscosity. 22. Hydrogen embrittlement manifests as a reduction in ductility and eventually spalling of titanium surfaces. 23. Each of these types of failure occur based on the material's ductility . 24. Glidcop also has excellent heading, or cold forming increase strength while reducing ductility . 25. Besides sliding electrical contacts, gold is also used in ductility and lack of toxicity. 26. Basic physical properties of metals include ductility , high strength, and high thermal conductivity. 27. Higher ductility of the CF / PEEK specimen shown, with values increasing with temperature. 28. Its ductility and malleability make it a compatible material to form over irregular roof structures. 29. The high ductility of copper allows for this process to be performed accurately and precisely. 30. It is observed that the higher the confining pressure, the greater the ductility observed.
