The Effects of Salt-Lake Salt Solution on the Strength of Expansive Soil by Shaowei Zhang, Dongdong Li

“…With the increase of the concentration of salt-lake solution, liquid limit, plastic limit, plastic index, free expansion rate, no load swelling, cohesion, and internal friction angle of expansive soil were decreased in varying degrees, and stress-strain relationship curve gradually showed strain softening trend. The reason for the above results was believed to be that salt-lake salt solution reduced the force between particles on shear surface and reduced mutual hindrance.…”

Role of Glass Composition on Mechanical Properties of Shape Memory Alloy-Metallic Glass Composites by Supat Chupradit, Indah Raya, Dinh Tran Ngoc Huy, Dmitry Bokov, Pham Van Tuan, Aravindhan Surendar, Doaa Alaa Lafta, Mustafa M. Kadhim, Olga Kravchenko, Yasser Fakri Mustafa, Zaid Hameed Mahmood, Sami Sajjadifar

“…Nevertheless, the excessive Zr addition in the MG composition facilitated the aggregation of nanopores at the interface of SMA and MGs, which may be due to the softening effect in the Zr-rich MGs. Finally, it is concluded that an optimized MG composition is required for the trade-off between the plasticity and the strength in the SMA-MG composites.…”
