Slip Localization Intensification Mediated by Grain Boundary Sliding in a Polycrystalline Nickel‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
The temperature dependence of fatigue behavior in nickel‐based superalloys is investigated through high‐resolution measurements of plastic localization. While increasing temperature reduces localization and enhances fatigue performance in René 88DT, Inconel 718 exhibits a sharp degradation at intermediate temperature due to intensified slip ...

Polarization behavior of pipelines with peeled anti-corrosive coating under pulsed current cathodic protection

open access: yesYou-qi chuyun
Objective Buried oil and gas pipelines are typically safeguarded by both anti-corrosive coating and cathodic protection. However, over time, the anti-corrosive coating degrades and may peel off during extended operation.

Positron annihilation study on defect repair of pure iron and RPV steel under electropulsing treatment

open access: yesHe jishu
BackgroundThe defects generated during the working process of metal materials have a significant impact on their performance. For example, the radiation-induced embrittlement and hardening of reactor pressure vessel (RPV) steels are a factor of concern ...

Determination of Optimal Pulse Current for ArcWelding

open access: yesElektronika ir Elektrotechnika, 2009
The manual and semi-automatic welding by pulse current (pulsing arc) is considered in the article. The advantages of welding by the pulsing arc are found out in comparison with welding by a constant arc. Using energetic calculation taking into account thermal balance at the electrode stub, optimal parameters of modulated current, such as frequency and ...
