The classic sliding wear model, represented by Archard's equation, has long been used to estimate the service life of equipment and guide selection modification tribo-materials. However, model was developed based on asperity contact geometry without directly dealing with wearing energy, rendering it unable precisely describe under some conditions, e.g., fails predict strain-hardened materials, which never clarified. In this study, incorporating plastic deformation–electron work function...
The hot compression tests of medium carbon V and V–Ti microalloyed steels are carried out at the temperature 900–1100 °C strain rate 0.01–10 s −1 . Three physical constitutive models based on creep theory studied, prediction accuracy is compared analyzed by employing correlation coefficient ( R ) average absolute relative error (AARE), deformation/diffusion mechanisms discussed. results show that Ti has obvious hardening effect in steel retards onset dynamic recrystallization. model...
Hot compression tests of low carbon (0.055C) and medium (0.37C) V-microalloyed steels were carried out in the temperature 900∼1100 C° strain rate 0.005∼10 s –1 . The influence on thermal deformation behaviour deformation/diffusion mechanism steel was studied by three physical constitutive models based creep theory. It is found that increase content has softening effect at rate, but hardening high rate. Different may lead to changes steel. 0.37C dislocation climb, while other appear 0.055C...
The hot deformation behavior of 22Cr‐25Ni austenitic heat‐resistant steel at the temperatures 950–1150 °C and strain rates 0.01–10 s −1 is studied by isothermal compression test. It found that dynamic recrystallization (DRX) degree increases with increase temperature. DRX decreases rate from 0.01 to 1 , whereas 10 . activation energy as high 624.25 kJ mol due addition a large number alloying elements. typical compensation Arrhenius constitutive model established can be used roughly predict...
The hot deformation behavior, dynamic recrystallization mechanism and processing maps of Ti-V complex microalloyed high strength steel under temperatures ranging from 840 to 1040 ℃ strain rates varying 0.01 10 s-1 were studied by using thermal-mechanical simulation (Gleeble-3800), optical microscopy (OM), electron backscatter diffraction (EBSD). results show that the rheological stress curves are type at 960~1040 rate 0.1 s-1, peak decreases gradually with increase temperature decrease rate....
The spring steel for automotive stabilizer bars has a great responsibility in that its quality directly affects the stability, safety, and comfort of vehicle operation. isothermal thermal compression behavior novel lean Si was used to manufacture an anti-roll bar investigated with DIL805A/D quenching dilatometer this research. A hyperbolic sine type constitutive model established, hot processing maps were produced evaluate experimental steel’s workability properties. results suggest dynamic...
Abstract In view of the low success rate logging in annulus fluid production profile domestic oil fields, relationship between instrument string and well deviation is carried out Requirements downhole instruments for annular testing construction highly deviated wells; The lifting lowering technology entry wells has been systematically studied. After field application, updated improved. By using large diameter cable, flexibly connecting splitting instruments, reducing outer configuring...
