In order to probe the superior nano/micron scale mechanical behaviors of ultra-fine grain (UFG) austenitic stainless steel as compared with coarse (CG) counterpart, systematic nanoindentation tests were carried out together post-mortem EBSD characterizations. Relatively higher nanohardness (Hn) was obtained in UFG both interior and boundary. This phenomenon had a relationship refinement. "grain interior" nanoindentation, matrix strength than CG, resulting from pre-existing dislocations...
The microstructure and mechanical properties of the novel cryogenic high-Mn austenitic steel weld metals with different cerium (Ce) contents were investigated via electron back-scattered diffraction, scanning spherical aberration-corrected transmission microscopy, impact tensile test. results indicated that crystallographic grain size was significantly refined, relative frequency high-angle boundaries increased increase Ce content. element addition could modify main inclusions from irregular...
The phase transformation from austenite to acicular ferrite in the simulated coarse grained heat affected zone of a high strength low alloy steel was investigated by means analytical characterisation techniques such as situ microscopy, transmission electron microscopy and backscattered diffraction analysis. grains nucleated on inclusions (Zr–Ti oxides) grain grew different directions effectively partitioned into several finer separate regions. crystallographic size became small for due...
In this paper, the effect of cold deformation on microstructures and mechanical properties 316LN austenitic stainless steel (ASS) was investigated. The results indicated that content martensite increased as rolling reduction also increased. Meanwhile, density grain boundary in untransformed austenite structure CR samples from 10% to 40%, leading a decreased size structure. These two factors contribute improvement strength decrease ductility. High yield strengths (780–968 MPa) with reasonable...
Three low‐carbon bainitic steels were designed to investigate the effects of Cr and Al addition on transformation, microstructures, properties by metallographic method dilatometry. The results show that compared with base steel without addition, only is effective for improving strength increasing amount bainite. However, steel, combined has no significant effect transformation properties. In Cr‐bearing accelerates initial but meanwhile reduces final due formation a high‐temperature product...
Abstract The austenite grain growth behavior in a simulated coarse-grained heat-affected zone during thermal cycling was investigated via situ observation. Austenite grains nucleated at ferrite boundaries and then grew different directions through movement of into the phase. Subsequently, adjacent impinged against each other α→γ transformation. After transformation, coarsened coalescence small boundary migration between grains. process continuous heating, isothermal holding, cooling cycling....
Microstructure, texture, mechanical properties, and magnetic properties of low carbon silicon non-oriented electrical steels annealed at 800 °C, 820 860 °C were studied. Fine precipitates (Al, Si, Mn)xNy-P, a small quantity Mn)xNy, the aforementioned composite containing MnS detected in samples °C. Compared with number density decreased by 20% average size increased 25 nm The grain was 22 μm, 26 μm 46 respectively. induction 0.027 T after annealing temperature from to iron loss reduced 0.94...
In this investigation, a Fe–20Mn–9Al-1.5C lightweight austenitic steel has been developed through strategic alloying with Ni and Cr elements coupled the employment of thermo-mechanical processing technique featuring ultra-fast cooling. This composition treatment synergistically transcend conventional trade-off between strength ductility, positioning mechanical performance notably above that comparable low-density steels previously reported. The coordinated incorporation is key to modulating...
