Hump on upper shelf of ductile-brittle transition temperature curve of a plain carbon steel [PDF]
The ductile—brittle transition temperature (DBTT) in a plain carbon steel has been studied in a series of Charpy V notch samples. Both non-standard and standard samples were used in the as drawn, normalised and annealed conditions.

ABSTRACT Polymeric blends are essential in the plastics processing industry for offering tailor‐made properties such as durability, flexibility, and toughness, and expanding applications. This study investigated, for the first time, the use of polyethylene grafted with acrylic acid (PE‐g‐AA) as a compatibilizer in blends of polyamide 6 (PA6) with ...

The microstructure of Cr‐rich Cr‐Si‐alloys is maintained by alloying with Ge, Pt, and Mo. The effects of these elements on A15‐phase fraction, partitioning, microstructural stability, grain size, and hardness are combinable. Molybdenum is found to be the most promising alloying element for microstructural stability during high‐temperature exposure.

Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

Cryogenic-Mechanical Properties and Applications of Multiple-Basis-Element Alloys
Multiple-basis-element (MBE) alloy was defined as the entropy of mixing over 1R (R is the gas constant, 8.31 J/k), and contains at least three principal elements, each one at over 5%.

Heat Treatment Effects on Microstructures and DBTT of F82H Steel Doped with Boron and Nitrogen
Effects of doping with 60 ppm B and/or 200 ppm N and heat treatments on the microstructures and the ductile-brittle transition temperature (DBTT) have been studied for ferritic/martensitic steel F82H. Prior austenitic grain size of standard F82H decreased from about 120 to 30 μm and also the DBTT decreased by about 50°C when the normalizing ...
