Under compressive loading, the Ti-based composites display high <span style=\"color:red\">fracture</span> strength (about 2000 MPa) and good ductility (about 4 or 10%). The yield strength of the Ti-based composites is relatively low (about 565-923 MPa). However, they have a large strain-hardening ability before failure, due to the interactions between shear bands and dendrites. For the arc-melted Ti-based composites, <span style=\"color:red\">fracture</span> often occurs in a shear mode with a high plasticity ( about 10%). In contrast, the cast Ti-based composites break or split into several parts with a compressive plasticity of 4%, rather than failing in a shear mode. A new <span style=\"color:red\">fracture</span> mechanism, i.e. distensile <span style=\"color:red\">fracture</span>, is proposed for the first time to elucidate the failure of the as-cast Ti-based composites.

The results show that grain boundary orientation has no effect on the creep deformation mechanism, but has a marked effect on the <span style=\"color:red\">fracture</span> mechanism. The creep <span style=\"color:red\">fracture</span> mechanism changes from a transgranular mode in longitudinal specimens to intergranular failure in transverse and inclined (45degrees to applied stress axis) specimens. Compared with constant load, cyclic load remarkably reduces creep life with the increment of cyclic frequency, but has no effect on the creep ductility. After careful examination of the transient response following the load changes, it is suggested that an intrinsic softening occurred during unloading, which accelerates the creep deformation rate on subsequent reloading, and the accumulation of this softening effect finally results in cyclic creep acceleration. The contribution of anelasticity has also been discussed.","authors":[],"categoryName":"|","doi":"","fpage":"73","id":"8e9d1e3f-c4ce-46ff-bb30-53379faad719","issue":"1","journal":{"abbrevTitle":"MSAT","id":"5c4ea523-f3ab-4618-9c21-537efff1d7fc","issnPpub":"0267-0836","publisherId":"MSAT","title":"Materials Science and Technology"},"keywords":[{"id":"b9c05612-4ed9-411d-98b9-89b4c120c6b6","keyword":"alloy;fatigue;mechanism;in738lc;stress","originalKeyword":"alloy;fatigue;mechanism;in738lc;stress"}],"language":"en","publisherId":"0267-0836_2002_1_1","title":"Effect of grain boundary orientation and cyclic load on creep and <span style=\"color:red\">fracture</span> <span style=\"color:red\">behaviour</span> in directionally solidified nickel base superalloy","volume":"18","year":"2002"}],"totalpage":161,"totalrecord":1601}
