ULTRA FINE FERRITE FORMATION IN Si-Mn TRIP STEELS
Abstract: In the present investigation, the effects of thermomechanical processing parameters and the steel chemical composition on the ultra fine ferrite formation characteristics were studied. This was programmed relying on the capabilities of strain induced transformation (SIT) phenomenon and applying to different grades of Si-Mn TRIP (Transformation Induced Plasticity) steels. According...
متن کاملSuperplasticity of a fine-grained Mg–1.5 wt% Gd alloy after severe plastic deformation
The strain rate sensitivity (SRS) of Mg–1.5 wt% Gd processed by conventional extrusion and 2 passes of simple shear extrusion (SSE) was investigated by shear punch testing. Shear punch tests were conducted at initial shear strain rates in the range of 0.003–0.3 s-1 and at temperatures in the range of 573–773 K. A fine-grained microstructure with an average grain size of about 2.5 µm, obtained a...
متن کاملEffect of plastic deformation on the formation of acicular ferrite
The effect of plastic deformation on the transformation of austenite to acicular ferrite in a Fe /Mn /Si /C alloy steel containing non-metallic inclusions was investigated. The transformation to acicular ferrite is retarded and the final fraction of acicular ferrite is reduced in plastically deformed austenite, which is a characteristic of a displacive transformation mechanism. The increase in ...
متن کاملUltra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...
متن کاملAchieving Incremental Compilation Through Fine-Grained Builds
Traditional programming environments represent program source code as a set of source files. These files have various ‘dependencies’ on each other, such that a file needs recompilation if it depends on a file which has changed. A ‘build tool’ is used to process these dependencies and bring the application ‘up-to-date’. An example of a build tool is the UNIX ‘make’. This paper examines what happ...
