“…It improves the tensile strength due to the mechanisms like precipitation hardening and grain size refinement. Anther studies also support these results [6]. The values of UTS increase remarkably after warm pressing due to grain refinement and predominantly attributed to the grain boundary strengthening, formation of microstructure and decrease porosity.…”

In this work, the effect of pressing technique on the microstructures and tensile behaviors of powder metallurgy (PM) steel with different composition were investigated. Weighed powders for the desired chemical composition were mixed in an industrial conic mixer for 1 h and then cold and warm pressed at 700 MPa with a die. The pressed PM steels were sintered at 1400 • C. PM steels with different pressing technique were analyzed in terms of micrstructure and tensile test. Results indicated that PM steels with warm pressing technique showed the highest values in yield strength (YS) and ultimate tensile strength (UTS).

“…In steel B22 pearlite reaction is for the most part inhibited, even though samples were cooled at still air (about 60 C/min). Manganese is well known to have the strongest retarding effect on diffusional decomposition of austenite, for elements present in both steels [11][12][13]. Since its content is practically equal in both steels, the higher hardenability in steel B22 is attributed to higher carbon content.…”

The aim of this work was to establish the deformation behavior of two vanadium microalloyed medium carbon steels with different contents of carbon and titanium by tensile testing at 77 K. Samples were reheated at 1250 C for 30 min and continuously cooled in still air. Beside acicular ferrite as the dominant morphology in both microstructures, the steel with lower content of carbon and negligible amount of titanium contains considerable fraction of grain boundary ferrite and pearlite. It was found that Ti-free steel exhibits a higher strain hardening rate and significantly lower elongation at 77 K than the fully acicular ferrite steel. The difference in tensile behavior at 77 K of the two steels has been associated with the influence of the pearlite, together with higher dislocation density of acicular ferrite.

“…4) Depending on the cooling intensity of the metastable austenite even before its phase transformation different microstructures with different properties are obtained, 5) especially throughout the cross-section of the products with large diameters. 6) To predict final microstructure and properties it is worth to obtain the exact thermal history of exact section of the product by means of direct temperature measurements, 7) numerical calculations 8) or combined experiments.…”

Applying the finite difference method for numerical solution of one dimensional heat transfer equation provides a simple way for cooling process simulation of hypoeutectoid low alloy steel rod (round long length bar). The obtained results are comparable with ones calculated using finite element modeling commercial software. The temperature difference of the proposed model and literature experimental data for 50…270 mm diameter bars cooled in still air and conventional oil does not exceed 25°C for the whole examined time-temperature regions before the phase transformation.
