Thermal Softening Effects in Type 224 Carbon Steel
An extensive investigation has been carried out on the compressive mechanical behaviour of type 224-carbon steel (0.18 wt % C, 1.21 wt % Mn) over the temperature range -110°C to +300°C and strain-rate 10" to 5000s", making possible the determination of the thermal sensitivity of this material. In several tests, a thermocouple was mounted inside each small cylindrical specimen to observe any tem...
متن کاملThe Strain Dependence of Post-Deformation Softening during the Hot Deformation of 304H Stainless Steel
Experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304H stainless steel. Three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the DRX critical strain: strongly strain dependent softening by SRX alone with softening kinetics control...
متن کاملExperimental investigations on the softening and ratcheting behaviors of steel cylindrical shell under cyclic axial loading
In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...

متن کاملPREDICTION OF STATIC SOFTENING OF MICROALLOYED STEEL BY THE INTEGRATION OF FINITE ELEMENT MODEL WITH PHYSICALLY BASED STATE VARIABLE MODEL
Abstract Recovery and recrystallization phenomena and effects of microalloying elements on these phenomena are of great importance in designing thermomechanical processes of microalloyed steels. Thus, understanding and modeling of microstructure evolution during hot deformation leads to optimize the processing conditions and to improve the product properties. In this study, finite element...
