Mg effect on the cryogenic temperature toughness of Al-Mg alloys

Materials & Design, 2022
In this study, the Mg and temperature effects on cryogenic impact toughness of Al-Mg alloys are investigated. Cryogenic Charpy impact tests are conducted for several Al-Mg alloys: AA5083 (=reference), Al-6 Mg, Al-8 Mg, and Al-8.5 Mg.

About the impact behavior of woven-ply carbon fiber-reinforced thermoplastic- and thermosetting-composites: A comparative study [PDF]

, 2013
This study is aimed at comparing the response of TS-based (epoxy) and TP-based (PPS or PEEK) laminates subjected to low velocity impacts. C-scan inspections showed that impact led to diamond-shaped damage resulting from different failure mechanisms ...

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 ...

Analysis of temperature effects near mode I cracks in glassy polymers [PDF]

, 2005
A previous isothermal study has shown that the toughness of glassy polymers is governed by the competition between shear yielding and crazing. The present work aims at investigating loading rates for which thermal effects need to be accounted for.

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.
