Elevated-temperature impact toughness of Mg–(Gd, Y)–Zr alloy [PDF]

, 2013
The Charpy impact results for Mg–10Gd–3Y–0.5Zr and Mg–11Y–5Gd–2Zn–0.5Zr alloys at various temperatures showed that Mg–10Gd–3Y–0.5Zr was more sensitive to temperature. The increase in impact toughness with temperature was related to the blunt crack-tip at

Impact toughness of multilayer steel materials at low temperatures

IOP Conference Series: Materials Science and Engineering, 2019
Abstract The results of a number of studies show that there are ways to drastically change the temperature dependence of the impact strength of structural steels, which at first glance have a paradoxical character. It was established that when the test temperature decreases down to cryogenic temperatures, the work of failure of impact ...

Impact toughness of Al-Li system alloys at low temperatures.

Journal of Japan Institute of Light Metals, 1987
Al-2.7%Li-1.2%Cu-0.8%Mg-0.1%Zr wrought alloys are heat treated to improve their impact toughness at lower temperatures, although a number of laminated cracks form in the vertical direction to the fracture surface. Low melting point elements, K and Na, are found on the fractured surface by Auger spectroscopy.
