Superplastic Bulging of Nanocrystalline Ni-Co Alloy with Different Heating Methods

摘要：

　　Superplasticity of nanocrystalline materials is a hot spot in the field of scientific research.In this paper,Ni-Co alloy was produced through pulse electrodeposition.Tensile tests were carried out to study the room temperature strength and high temperature plasticity.The superplastic formability under complex stress was evaluated through the superplastic bulging tests.The tests were studied through the methods of resistance heating and furnace temperature heating.The maximum ratios of height and diameter with different heating methods were compared.Fracture behavior and microstructure were observed by the method of SEM.
