Influence of preheating on tungsten damage under pulsed hydrogen plasma exposure

open access: yesNuclear Materials and Energy
Preheated tungsten plate behavior under multiple pulsed hydrogen plasma irradiations in the PW-7 plasma accelerator was investigated. The preheating temperature was 973 K, which is above the ductile to brittle transition temperature (DBTT ≈ 673 K).

Heat Treatment Effects on Microstructures and DBTT of F82H Steel Doped with Boron and Nitrogen

open access: yesMATERIALS TRANSACTIONS, 2005
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 ...
