The Effects of Cr and Al Addition on Transformation and Properties in Low-Carbon Bainitic Steels
Three low-carbon bainitic steels were designed to investigate the effects of Cr and Al addition on bainitic transformation, microstructures, and properties by metallographic method and dilatometry. The results show that compared with the base steel without Cr and Al addition, only Cr addition is effective for improving the strength of low-carbon bainitic steel by increasing the amount of bainit...
متن کاملAN 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 کاملMicroscopic modelling of simultaneous two-phase precipitation: application to carbide precipitation in low-carbon steels
A thermodynamically-based precipitation model, employing the classical nucleation and growth theories, has been adapted to deal with simultaneous precipitation of metastable and stable phases. This model gives an estimation of the precipitation kinetics (time evolution of radius and density of precipitates for both phases, as well as the evolution of solute fraction) in a wide range of temperat...
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...
