Abnormal Grain Growth in Ferritic-Martensitic Eurofer-97 SteelAbstract. Ferritic-martensitic steels like Eurofer-97 are candidate structural materials for future fusion reactors. In the tempered state, this steel contains fine particles dispersed in the ferritic matrix. The aim of this work is to investigate abnormal grain growth in Eurofer-97 steel. The microstructural evolution was followed by isothermal annealing between 200 and 800°C (ferritic phase
Nov 15, 2014 · - Highlights: Abnormal grain growth (secondary recrystallization) in AISI 304L stainless steel Exaggerated grain growth due to dissolution/coarsening of carbides The enrichment of carbide particles by titanium Abnormal grain growth due to grain boundary faceting at very high temperatures The stagnancy of abnormal grain growth by annealing beyond a critical time.} doi =
Elucidating the effect of intermetallic compounds on the The abnormal grain growth occurred by penetrating into grain boundaries of smaller grains and by the formation of discrete islands inside large abnormal grains, which provided evidence for the occurrence of the solid-state wetting mechanism in this magnesium alloy.

Grain growth kinetics in an AISI 347 stainless steel with Nb content up to 0.7%wt was studied during the isothermal holding in the temperature range of 1100-1270°C for various periods. Abnormal grain growth was observed even in the presence of a large amount of precipitates. The kinetics of normal grain growth was tracked by metallographic measurements and fitted by the classical modeling

Review Annealing of Cold-worked Austenitic Stainless ment16) a common steel such as the AISI 304 can have its yield strength increased to about 1400MPa, with an elon-gation over 10%.1) During plastic deformation, depending on the steel composition and the cold working variables, some induced martensite can be formed. This martensite is usually called deformation induced martensite, DIM,7

Study of The Microstructure of Aisi Steel 304l in Wz, Haz refining and grain growth. In recent years, has been developed many studies on welding of Steel AISI 304L, for example, , studied the ZF microstructure in FZ after welding process, It was observed that the dimensions of the BM, HAZ and WZ have been proportionate to the increased heat imput, studied thermal effects by numerical modeling via
texture investigation in welded 304L stainless steel . EBSD analysis of the as-welded specimens revealed that the primary solidification occurred in <101> direction and grain growth occurred in either <001> or <111> direction depending on the variable welding parameters . In our previous work ,
Thermal Stability Study of Ultrafine Grained 304L An ultrafine grain 304L stainless steel with average grain size of about 650 nm was produced by martensitic process. 10 mm as-received sheets were 80% cold rolled in the temperature of 15 °C and then annealed at 700 °C for 300 min to obtain ultrafine grained microstructure.(PDF) Abnormal Grain Growth in AISI 304L mohammad Abnormal Grain Growth in AISI 304L
