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.
