Achieving High Strength and Tensile Ductility in Pure Nickel by Cryorolling with Subsequent Low-Temperature Short-Time Annealing

Zhide Li,Hao Gu,Kaiguang Luo,Charlie Kong,Hailiang Yu,

Engineering doi: 10.1016/j.eng.2023.01.019

Abstract: strength of 607 MPa and a uniform elongation of 11.7% were obtained after annealing at a small cryorolling strain(ε = 0.22), while annealing at a large cryorolling strain (ε = 1.6) resulted in ahardening during cryorolling, with an additional contribution from grain refinement and the formationcould be attributed to annealing twins and micro-shear bands during stretching, which improved the strainhardening capacity.

Mixed mode properties of CNT reinforced composites using Arcan test rig

Jacob MUTHU

Frontiers of Structural and Civil Engineering 2015, Volume 9, Issue 4,   Pages 397-404 doi: 10.1007/s11709-015-0321-y

Abstract: Composite materials reinforced with carbon nanotubes were mechanical tested using Arcan test rig under Mode-I, Mode-II and mixed mode loading conditions to obtain their fracture properties. The butterfly composite specimens were fabricated with 0.02, 0.05 and 0.1 wt % CNTs. The polyester/CNT composite was fabricated using VRTM (Vacuum Resin Transfer Molding) where the CNTs were first functionalised to reach an optimum properties. Arcan test rig was designed and fabricated to work with the Shimadzu testing machine. The results show that the functionalised CNTs have improved the fracture behavior by acting as bridge between the cracked face. In addition, the fracture properties were not improved for the higher weight fraction of 0.1 wt% CNTs.
