Corrigendum: Inclusion flotation-driven channel segregation in solidifying steels
Channel segregation, which is featured by the strip-like shape with compositional variation in cast materials due to density contrast-induced flow during solidification, frequently causes the severe destruction of homogeneity and some fatal damage. An investigation of its mechanism sheds light on the understanding and control of the channel segregation formation in solidifying metals, such as s...
متن کاملŠevčík: High Temperature Strength Analysis of Low Carbon Steels in the as - Cast State
High-temperature properties of the continually cast low carbon steel slabs are tested on various equipments [1 7]. The high temperature tensile strength test is the most used one and the primary evaluated quantity, plasticity, is mostly assessed by reduction of area values. Several heating techniques are used for high temperature tensile strength tests and the testing is performed at various de...
متن کاملHigh Temperature Mechanical Properties of the As-cast Low Carbon Steels and Their Prediction
Steel undergoes multiple phase transformations during casting and various forces of technological origin affect a slab in the casting machine. As a consequence of these infl uences, various types of defects arise during the casting process [1 5]. The slab surface quality is a crucial factor for quality of the end products, especially of the fl at ones. Plasticity of the steel is a further, very...
متن کاملGrain Boundary Segregation in Commercial Nuclear Reactor Pressure Vessel Steels
Grain boundary (GB) segregation of impurity/solute atoms in surveillance test specimens of a commercial western-type pressurized water reactor pressure vessel (RPV) steel has been observed by using state-of-the-art 3D atom probe (3DAP) field ion microscope (laser-assisted local electrode-type atom probe: laser-LEAP). The GB segregation is considered to be an origin of the embrittlement of the R...
متن کاملSolidification Phenomena and Properties of Some Cast Tool Steels
The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...
