The Significance of Coherent Transformation on Grain Refinement and Consequent Enhancement in Toughness. [PDF]

Materials (Basel), 2020
Coherent transformation is considered to be an effective approach to refine the microstructure and enhance toughness of structural steels. However, there are gaps in the knowledge on the key aspects of microstructure that govern toughness. In this regard,

Effect of Strain Rate on Ductile-to-Brittle Transition Temperature of a Free-Standing Pt-Aluminide Bond Coat

, 2011
The ductile-to-brittle transition temperature (DBTT) of a free-standing Pt-aluminide (PtAl) bondcoat was determined using the microtensile testing method and the effect of strain rate variation, in the range 10−5 to 10−1 s−1, on the DBTT studied.

Effect of Microstructure on Low-Temperature Fracture Toughness of a Submerged-Arc-Welded Low-Carbon and Low-Alloy Steel Plate

Metals, 2021
This study investigated the low-temperature fracture behavior of an 80-mm-thick low-carbon steel plate welded by submerged arc. The relationship between impact absorbed energy and ductility–brittle transition temperature (DBTT) based on the ...

Effects of electroslag remelting process and Y on the inclusions and mechanical properties of the CLAM steel

Nuclear Engineering and Technology, 2020
Y-containing CLAM steels were melted via vacuum induction melting and electroslag remelting. In this study, the evolution, microstructure, and mechanical properties of the alloy inclusions (ESR-1 (0 wt.% Y), ESR-2 (0.016 wt.% Y) and ESR-3 (0.042 wt.% Y))

The Effect of Phosphorus on Low-Temperature Brittleness in the Coarse-Grained Heat-Affected Zone of P-SA508-4N RPV Steel

Metals
The coarse-grained heat-affected zone (CGHAZ) is a critical brittle region in welded reactor pressure vessel steels, and phosphorus segregation at prior-austenite grain boundaries can further impair its low-temperature toughness during long-term service.

Essential work of fracture and absorbed energy by Charpy impact test of TRIP780 1.5 mm thick sheet steel Kerbschlagarbeit und absorbierte Energie bei der Charpy‐Schlagprüfung an 1,5 mm dickem Restaustenitstahlblech (HCT 780)

Materialwissenschaft und Werkstofftechnik, Volume 57, Issue 9, Page 895-907, September 2026.
The study demonstrated that absorbed energy (Charpy impact test) and fracture toughness (EWF test) are essential for evaluating the mechanical performance of thin sheet metallic materials. Transformation‐induced plasticity (TRIP) steels have been extensively studied concerning their mechanical performance under monotonic loading and conventional ...
