Petch properties
WebThe dynamic Hall-Petch relation was established by the effective grain size, which was similar at strains of up to 0.20 in Ti-15Mo alloy with static grain sizes of 29 μm and 108 μm. The decreasingly modified Hall-Petch coefficient was resulted from the successive occurrence of twinning activation, twinning suppression, and the twin ...

WebGrain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. The size of the grain … WebIn controlling grain growth, it improves both the strength and toughness of hardened and tempered steels. The size of the grain determines the properties of the metal. For example, smaller grain size increases tensile strength and tends to increase ductility. A larger grain size is preferred for improved high-temperature creep properties. Tungsten.
