Effect of Nanosized NbC Precipitates on Hydrogen Diffusion in X80 Pipeline Steel
In this paper, the effects of dispersed 3~10 nm NbC precipitates on hydrogen diffusion in X80 pipeline steel were investigated by means of high resolution transmission electron microscopy (HRTEM), electrochemical hydrogen permeation, and thermal desorption spectroscopy (TDS). The relationship between hydrogen diffusion and temperature was determined for Nb-free X80 and 0.055 wt% Nb X80 steel. T...
متن کاملCharacterization of Aging Behavior of Precipitates and Dislocations in Copper-based Alloys
The growth of precipitates in a deformed Cu Ni Si alloy with an aging treatment and the rearrangement of dislocations were investigated using X-ray scattering methods. A small angle X-ray scattering (SAXS) method was used for characterizing the growth behavior of the precipitates with aging. The results showed that the precipitates grew gradually to a few nanometers in radius in the alloy aged ...
متن کاملNanosized precipitates in H13 tool steel low temperature plasma nitriding
A comprehensive study of pulsed nitriding in AISI H13 tool steel at low temperature (400°C) is reported for several durations. X-ray diffraction results reveal that a nitrogen enriched compound (-Fe2-3N, iron nitride) builds up on the surface within the first process hour despite the low process temperature. Beneath the surface, X-ray Wavelength Dispersive Spectroscopy (WDS) in a Scanning Elec...
متن کاملUnderstanding dual precipitation strengthening in ultra-high strength low carbon steel containing nano-sized copper precipitates and carbides
Low carbon ferritic steel alloyed with Ti, Mo and Cu was hot rolled and interrupt cooled to produce nano-sized precipitates of copper and (Ti,Mo)C carbides. The steel had a tensile strength of 840 MPa, an increase in yield strength of 380 MPa over that of the plain carbon steel and reasonable ductility. Transmission electron microscopy and small angle neutron scattering were used to characteriz...
