Effect of heat treatment on microstructure and hydrogen embrittlement of additively manufactured and cast 18Ni300 maraging steel

Journal of Materials Research and Technology
The microstructure is significantly different between cast and additively manufactured 18Ni300 maraging steel due to the different manufacturing principles. The resulting differences in hydrogen embrittlement susceptibility need to be clarified. Electron

Reinforcement and Rheology of Epoxy‐Mediated Lignin Integration in Carboxylated Nitrile Rubber

Polymer Engineering &Science, EarlyView.
The interaction of lignin‐epoxy resin‐XNBR and the effect of lignin on the nonlinear rheological behavior of epoxy‐cured XNBR/lignin composites. ABSTRACT Lignin has attracted increasing interest as a renewable filler for rubber composites; however, it shows weaker reinforcing efficiency than conventional fillers such as carbon black and silica ...

Aggregation‐induced enhanced emission for quantification of recycled content in automotive plastics

Polymer International, EarlyView.
Quantifying recycled content in four automotive plastics using aggregation‐induced enhanced emission showed that performance was highly dependent on both polymer and additive chemistries. Abstract The use of plastics in the automotive industry is increasing due to their versatility, light weight and affordability.

Hydrogen Embrittlement of Steel

Zairyo-to-Kankyo, 2011
鉄鋼材料の水素脆化全般をまとめ，その対策として，水素侵入抑制を鋼材側から検討した例を述べた．スケール直下のNi濃化層を活用することにより，水素侵入を抑制し，水素脆化を抑制できた．また，高合金化すると，素材としての水素脆化特性は良好となっても，ボルトなど実部品を用いた水素脆化特性は必ずしも良好とはならない．これは接触腐食による水素侵入が増大するためで，Ni多量添加によって抑制可能である．

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels

steel research international, EarlyView.
The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Barriers to Steel Decarbonization

steel research international, EarlyView.
Main identified barriers to steel decarbonization Carbon dioxide (CO2) emissions are a leading contributor to global climate change, necessitating urgent mitigation strategies. While various metrics—such as total national emissions, per‐capita output, and historical contributions—define responsibility, determining accountability remains complex ...
