41. This leads to an increase in the yield strength of the material and a subsequent decrease in ductility . 42. Crystals in metals have a major effect of the physical properties of the metal including strength and ductility . 43. Skin-rolled stock is usually used in subsequent cold-working processes where good ductility is required. 44. It was found that the ductility measurement in a standard tension test includes local ductility and uniform ductility. 45. It was found that the ductility measurement in a standard tension test includes local ductility and uniform ductility. 46. It was found that the ductility measurement in a standard tension test includes local ductility and uniform ductility . 47. PSM 100 has the same ductility and fatigue resistance as PSM 70 but with a more porous structure. 48. Since cementite is much harder than pearlite, the alloy has greater hardenability at a cost in the ductility . 49. Elements such as copper or tin may be added to increase tensile and yield strength while simultaneously reducing ductility . 50. Cold-worked steel normally tends to possess increased hardness and decreased ductility , making it difficult to work.
