Hot ductility of Fe-36Ni invar alloy

工程科学学报, 2016
The hot ductility behaviors of Fe-36Ni alloy in the temperature range of 900-1200 ℃ were investigated by using a Gleeble-3800 thermal simulator. The influence factors and mechanism of action on the hot ductility were systematically analyzed by FaetSage ...

Multi-frequency topological derivative for approximate shape acquisition of curve-like thin electromagnetic inhomogeneities

, 2012
In this paper, we investigate a non-iterative imaging algorithm based on the topological derivative in order to retrieve the shape of penetrable electromagnetic inclusions when their dielectric permittivity and/or magnetic permeability differ from those ...

Effect of Ce on inclusions and carbides in M2 high-speed steel

工程科学学报
Two heats of M2 high-speed steel with different rare-earth (Ce) contents were produced by a domestic steel plant using the following process route: electric arc furnace (EAF) smelting → ladle furnace (LF) refining → vacuum degassing (VD) → electroslag ...

Production technology and welding properties of high heat input welding EH420 offshore steel

工程科学学报, 2020
Extensive efforts have been made to remove “harmful” inclusions during the steelmaking process. However, the concept of “oxide metallurgy” was proposed, where fine inclusions are used to induce the formation of acicular ferrite and pin the grain boundary,
