Experimental Study on the Uniaxial Cyclic Deformation of 25CDV4.11 Steel

Guozheng KANG , Qianhua KAN , Juan ZHANG

材料科学技术（英文）

The strain cyclic characteristics and ratcheting behavior of 25CDV4.11 steel were studied by the experiments under uniaxial cyclic loading with relatively high cyclic number and at room temperature. The cyclic hardening/softening feature of the material was first observed under the uniaxial strain c...

Uniaxial Ratcheting Behaviors of Metals with Diffent Crystal Structures or Values of Fault Energy: Macroscopic Experiments

Guozheng Kang

材料科学技术（英文）

The uniaxial ratcheting behaviors of several metals with different crystal structures or values of fault energy were observed by the stress-controlled cyclic tests at room temperature. The prescribed metals included 316L stainless steel, pure copper, pure aluminum, and ordinary 20# carbon steel. The...
