High through-put nanoindentation mapping and indentation creep behavior of P-TIG welded CpTi and Inconel 718 using a Nb-interlayer
Abstract
<p>The high-speed correlative study of the local mechanical properties and indentation creep of different zones of the P-TIG welded CpTi (Commercially pure Ti) and IN718, with Nb as an interlayer has been studied. The results showed contrasting mechanical properties (nanohardness and elastic moduli) to a width of 35 µm and 60 µm at the Nb/CpTi and the Nb/IN718 interfaces with hardness of ∼9 GPa and ∼15 Gpa, respectively. This was owing to the strengthening of the interfaces due to the interdiffusion of Nb into the base alloys. The Nb/IN718 and Nb/CpTi interfaces, exhibited significantly higher resistance to creep deformation than the Nb-Interlayer. The stress exponent at the Nb/CpTi interface and in different zones of Nb/IN718 side indicated dislocation climb as the creep deformation mechanism.</p>
