| 中文摘要 | The effect of solution treatment (ST) on tensile properties of M963 Ni-base superalloy tested at 800 degrees C has been investigated. The detailed microstructures, fracture surfaces and dislocation structures are examined through energy dispersive X-ray analysis (EDAX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). With increasing solution treated temperature, the yield strength (YS) and ultimate tensile strength (UTS) increase, however, the elongation decreases. Microstructural observations show that the morphologies of carbide, primary gamma' and re-precipitated gamma' change significantly with increasing solution treated temperature. The main deformation mode is gamma' by-pass when solution treated temperature is lower than 1220 degrees C, and changes to gamma' shearing at 1230 degrees C. The interface of carbide with matrix is the main site of crack initiation and propagation under all testing conditions. (c) 2005 Elsevier B.V. All rights reserved. |
