Effects of Rare Earth on Austenite–Ferrite Phase Transformation in a Low-Carbon Fe–C Alloy
نویسندگان
چکیده
The influence of rare earth (RE) elements on austenite–ferrite phase transformation in Fe–0.14%C alloy has been investigated by situ observing the nucleation, growth and morphology ferrite using high temperature laser scanning confocal microscopy, controlled atmosphere decarburization experiments. It is found that under low-oxygen condition steel, trace RE addition can significantly combined effects slowing down carbon diffusion decreasing grain boundary energy segregating at boundaries. This research provides evidences adjusting improving mechanical properties steels addition.

Magnesium-rare earth based alloys are increasingly being investigated due to the formation of highly stable strengthening phases, activation of additional deformation modes and improvement in mechanical properties. Several investigations have been done to study the effect of rare earths when they are alloyed to pure magnesium and other Mg alloys. In this review, the mechanical properties of the...

critical period effects in foreign language learning:the influence of maturational state on the acquisition of reading,writing, and grammar in english as a foreign language
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
