High-current gas tungsten arc welding of Ni-base superalloy Haynes 282: correlating heat input with weld profile, microstructure, hardness and indentation size effect

Materials Science and Technology
Increasing the linear heat input during high-current gas tungsten arc welding (GTAW) of Haynes 282 leads to a progressive change from conduction mode welding to one with keyhole formation.

EBSD and Nanoindentation-Correlated Study of Delamination Fracture in Al-Li Alloy 2090 [PDF]

, 2008
Al-Li alloys offer attractive combinations of high strength and low density. However, a tendency for delamination fracture has limited their use. A better understanding of the delamination mechanisms may identify methods to control delaminations through ...

A new nanoindentation approach for determining both indentation size effect and continuous apparent activation volume during loading of nanocrystalline Ni and Ni-20 wt% Fe alloy

Journal of Materials Research and Technology
A new nanoindentation approach is developed in this study to determine both indentation size effect (ISE) and continuous apparent activation volume (V) during loading of nanocrystalline nickel (NC Ni) and nanocrystalline nickel-20 wt% iron alloy (NC Ni ...

An Examination of the Indentation Size Effect In FCC Metals and Alloys from a Kinetics Based Perspective Using Nanoindentation [PDF]

, 2016
The indentation size effect (ISE) in metals is described as the rise in hardness with decreasing depth of indentation and contradicts conventional plasticity behavior.
