Effects of spinodal decomposition induced by thermal aging on the hydrogen embrittlement response of Fe-20Cr-5Al alloy

Journal of Materials Research and Technology
To understand the hydrogen embrittlement mechanism in the Fe-20Cr-5Al alloy for high-temperature hydrogen applications, the effects of thermal aging on hydrogen embrittlement were investigated.

Investigation of Low-temperature Solders for Cryogenic Wind Tunnel Models [PDF]

, 1985
The advent of high Reynolds number cryogenic wind tunnels has forced alteration of manufacturing and assembly techniques and eliminated usage of many materials associated with conventional wind tunnel models.

Compatibilization Mechanisms of Telechelic Polyethylene Reactive Additives in Polyethylene Terephthalate/Polyethylene Blends

Journal of Polymer Science, EarlyView.
A deeper understanding of reactive blend compatibilization using hydroxy telechelic polyethylene additives in blends of glycol‐modified polyethylene terephthalate and polyethylene is developed. Preformation of copolymer during reactive mixing is key for successful compatibilization of this system at lower mixing temperatures. ABSTRACT Imperfect sorting

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels

steel research international, EarlyView.
On the pathway to climate‐neutral steel production, recycling fractions will necessarily increase over time. Since alloying elements will enrich progressively, as they cannot be removed economically from the melt, processes need to be adjusted.

Recycling‐Induced Copper Contamination of a 42CrMo4 Quench and Tempering Steel—Scaling and Susceptibility to Hot Shortness

steel research international, EarlyView.
In this study, the susceptibility to copper‐induced hot shortness of the alloy 42CrMo4 is investigated by different hot tensile tests, as well as by a detailed analysis of the formed oxidation products. While an enrichment of metallic copper and a penetration of the grain boundaries are observed, no critical reduction of the tensile test properties can

Alteration of Phase Transformation Behavior and Prior Austenite Grain Structure Due to Elevated Tramp Element Concentrations in a Hypoeutectoid Steel

steel research international, EarlyView.
The phase transformation behavior of a hypoeutectoid steel is studied in comparison with alloys containing higher concentrations of tramp elements, simulating high recycling rates. The examination of microstructures reveals that the tramp elements facilitate the formation of displacive phases along with retained austenite.
