AN INVESTIGATION TO BAINITE FORMATION MORPHOLOGIES IN NI-CR BEARING LOW CARBON STEELS THROUGH THERMOMECHANICAL PROCESSING
The presence of bainite in the microstructure of steels to obtain a proper combination of strength and toughness has always been desired. The previous works however have shown that the presence of preferred bainite morphologies in the microstructure of any steel would not be readily accessible. In addition, the appearance of different bainite morphologies in the microstructure of any steel is d...
متن کاملan investication into the strain aging of low carbon steels
in this paper, the effect of prestrain on strain aging of low carbon steels, in the temperatures of 100°c and 200°c and the aging time of 50 minutes, and also the effect of aging temperature on strain aging in a constant aging time and prestrain, are investigated. the results of experiments show that with increasing the amount of prestrain, the increase in yield stress and ultimate tensile stre...
متن کاملCarbon Analysis in Low-alloy and Carbon Steels with Handheld LIBS
Presented here is a method to analyze carbon content in low alloy and carbon steels, utilizing the technique of handheld laser induced breakdown spectroscopy (HH LIBS). The method specifies the SciAps Z-200, the world’s only handheld analyzer capable of analyzing carbon content in alloys. The Z-200 uses a pulsed, 1064 nm laser, operating at 5.5 mJ/pulse and 50 Hz repetition rate. The onboard sp...
متن کاملQuantitative measuring of pearlite in carbon steels using electromagnetic sensor
Non-destructive Eddy current (EC) technique has long been used to detect discontinuities in materials. Recently, its application has been extended to characterize materials microstructure. In order to identify different microstructures, four plain carbon steel bars with different chemical compositions (AISI 1015, 1035, 1045 and 1080) were used in annealed condition. The pearlite percentage, car...
متن کاملMathematical Modeling of the α→γ Phase Transformation during Heating in Low Carbon Steels
The purpose of this research is to develop a model for the ferrite-to-austenite transformation on heating which would include the possibility of the change in the character of the transformation from diffusional to mixed-mode and would be less computationally demanding. A physics-based model is constructed for the ferrite-austenite phase transformation of low carbon steels. The model is descret...
