Influence of Heat Treatment Time and Temperature on the Microstructure and Corrosion Resistance of Cast Superaustenitic Stainless Steels
The influence of heat treatment time and temperature on the microstructure and corrosion resistance of cast stainless steel alloys CN3MN (UNS J94651) and CK3MCuN (UNS J93254) were investigated with a combination of microscopy techniques and immersion corrosion testing. The as-cast alloys exhibited significant residual microsegregation of Mo across the dendritic substructure and the presence of ...
متن کاملHigh Temperature Behavior of Dual Phase Steels
Dual phase steels with different martensite volume fraction and morphology were tensile tested at a temperature range of 25 to 5500C. Stress-strain curves of all steels showed serration flow at temperatures of 250 and 3500C, and smooth flow at the other temperatures. Both yield and ultimate tensile strengths increased with increasing testing temperature up to about 450<sup...
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...
