Optimization of composition for thick NM450 steel plates and elimination of delayed cracking phenomena

Materials Research Express
To address the phenomenon of delayed cracking during the flame cutting of traditional thick NM450 steel, a new variant, 0Ni-NM450 steel, was developed.

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

Influence of Microstructure on the Corrosion Resistance of Low Carbon Uns S41003 Stainless Steel [PDF]

Materials Research
The UNS S41003 (ASTM A1010) is a lean stainless steel with a chromium content of 10.5-11.0%. Its relatively low cost and enhanced corrosion resistance make it a promising alternative to carbon steels in various applications.

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.

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

Datasets acquired with correlative microscopy method for delineation of prior austenite grain boundaries and characterization of prior austenite grain size in a low-alloy high-performance steel

Data in Brief, 2019
Prior studies on martensitic steel microstructures have either delineated the prior austenite grain boundaries via chemical etching or reconstructed the prior austenite grains from crystallographic orientations measured with electron backscattered ...
