| 英文摘要 | The microstructural evolution and matrix-carbide load transfer in a nickel-based alloy (GH3535) under tension were investigated by in situ high-energy X-ray diffraction. The sample containing smaller carbides (1-3 mu m) shows obvious load transfer from the matrix to the carbides during the initial elastic deformation. However, the sample with larger carbides (10-20 mu m) shows no remarkable load-transfer behavior. The sample with smaller carbides possesses slightly higher yield strength and lower ultimate tensile strength than the sample with larger carbides. These results are attributed to indirect strengthening by dislocation obstruction in the sample with larger carbides and direct strengthening via load transfer for that with smaller carbides.
