Creep of nearly lamellar TiAl alloy containing W
Effects of W on the creep resistance of two nearly fully lamellar TiAl alloys with 1.0 and 2.0 at.% W have been investigated. In the low stress regime (LS) a nearly quadratic (1:5 < n < 2) creep behavior was observed. It is found that the addition of W can improve the creep resistance; however, the addition of excess W can result in the formation of b phase, which produces an adverse effect on ...
متن کاملThermal-cycling creep of g-TiAl-based alloys
In two-phase TiAl-based alloys, the coexisting 2 and phases exhibit a thermal expansion mismatch, so that increased creep rates during thermal cycling may be expected. Creep deformation of two g-TiAl-based alloys was investigated during thermal cycles between 900 and 300 or 350 C with applied tensile stresses of 32.5 or 37.0 MPa. Measured thermal cycling creep rates were compared with isotherma...
متن کاملDeformation Behavior of Intermetallics: Models and Experiments
A sufficiently general thermally activated mechanism for extension of dislocations in some preferential direction was proposed. This mechanism comprises a necessary step of dislocation transformations that lead to blocking. The reasons for blocking of different types of dislocations in different materials are diverse. A new concept was developed concerning the possibility of thermally activated...
متن کاملNon-Fermi liquid behavior in U and Ce intermetallics
In this paper we review the current experimental and theoretical situation of the description of non-Fermi liquid behavior (NFL) in U and Ce intermetallics. We focus on the magnetic and thermodynamic properties. We also discuss a recent theoretical interpretation of this behavior in terms of Griffiths-McCoy singularities close to the magnetic quantum critical point (QCP). We show how an effecti...
متن کاملCreep Mechanisms and Interface-Enhanced Deformation Twinning in a Two-Phase _ Lamellar TiAl Alloy
Deformation mechanisms and the role of interfaces in deformation twinning of a two-phase [TiAI (y)GAl (ad] 1 amellar allo\t creep deformed at elevated temperatures have been investigated. Since the multiplication of lattice dislocations \vithin both y and a2 lamellae is verl\’ limited at a lo\v stress level due to a refined lamellar microstructure, the glide of interfacial dislocations on both ...
