Effect of Different Power Supply Modes on Inclusion in 304L Stainless Steel Electroslag Ingot

Metals, 2023
The use of low frequency or DC (i.e., direct current) operation in the electroslag remelting process may lead to the electrolysis of some oxides in the slag pool, which will adversely affect the cleanliness of the electroslag ingot.

Effective Electroslag Remelting of Superalloys

Superalloys 1972 (Second International Symposium), 1972
In order to take full advantage of electroslag remelting, it is necessary to optimize the most important properties, such as structure, chemical uniformity and inclusion control by careful choice of the remelt parameters, since these properties essentially determine the acceptability of the final part.

A Future for Vacuum Arc Remelting and Electroslag Remelting—A Critical Perspective

Metals, 2023
In the secondary metals refining processes, vacuum arc remelting (VAR) and electroslag remelting (ESR), the consumable electrode is commonly produced by vacuum induction melting (VIM) which employs the regrettably primitive casting technique of simply ...

Coalescence‐Ripening Mechanism of γ′−Ni3(Al, Ti) During Long‐Term/High‐Temperature Operation of Ni‐Based Superalloy Discs

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The evolution of the γ′−Ni3(Al, Ti) phase in superalloys is governed by a coupled coalescence‐ripening mechanism driven by elemental diffusion. In this study, thermal exposure experiments were performed at 750°C and 800°C for durations ranging from 100 to 20,000 h.

A Perspective on Powder Metallurgy and Additive Manufacturing of High‐Nitrogen Alloyed Stainless Steels

Advanced Engineering Materials, Volume 27, Issue 14, July 2025.
This perspective article explores an innovative powder metallurgical approach to producing high‐nitrogen steels by utilizing a mixture of stainless steel and Si3N4. This mixture undergoes hot isostatic pressing followed by direct quenching. The article also examines adapting this method to laser powder bed fusion (PBF‐LB/M) to overcome nitrogen ...

Directional solidification of aluminum-nickel eutectic alloys using electroslag remelting [PDF]

, 1979
Attempts were made to produce directionally solidified, specifically grain aligned Al-6 wt pct Ni eutectic alloy using a laboratory scale ESR unit. For this purpose sand cast alloy electrodes were electroslag remelted under different mold conditions. The
