-form deformation (FFD). The affine transformation performed a rough registration targeting the mismatch between the CT and MR images. The B-splines FFD transformation performed a finer registration......
New type of groove used to improve friction in roll forgingJIA Zhi(贾智) , ZHOU Jie(周杰), JI Jin-jin(姬金金) (School of Materials Science and Engineering, Chongqing University, Chongqing 400044, China)Abstract:A FEM model for a failed industrial example of roll forging was established to analyze the generation mechanisms of the mismatch of size and shape of two spring board. To demonstrate......

in the direction where the mismatch between γ′ and γ reduces; the occupation probabilities are anisotropic in space; and direction coarsening of L12 occurs finally. With a rise of ageing temperature, phases... simulation; directional coarsening; anisotropic growth; mismatch; diffusion 1 Introduction γ′ (L12) is the main strengthened phase of nickel-based superalloys which have significantly raised operating......
content increases, the interfaces of γ/γ′ become orderly, the atomic arrangements at interfaces are more uniform, the number of mismatch dislocations increases and transition areas between γ and γ′ phases... observation on three experimental single crystal superalloys after heat treatment. Coherent structures are clearly observed at interfaces in all three tested alloys. There are some mismatch......
