Characteristic Points of Stress-Strain Curve at High Temperature
Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...
متن کاملHigh Strain Ra 33 . High Strain Rate and Impact Experiments
Experimental techniques for high-strain-rate measurements and for the study of impactrelated problems are described. An approach to classifying these experimental techniques is presented, and the state-of-the-art is briefly described. An in-depth description of the basis for high-strain-rate experiments is presented, with an emphasis on the development of a range of strain rates and a range of ...
متن کاملHigh strain rate properties of metals and alloys
The high strain rate dependence of the flow stress of metals and alloys is described from a dislocation mechanics viewpoint over a range beginning from conventional tension/compression testing through split Hopkinson pressure bar (SHPB) measurements to Charpy pendulum and Taylor solid cylinder impact tests and shock loading or isentropic compression experiment (ICE) results. Single crystal and ...

متن کاملEffect of temperature on the high strain-rate fracture characteristics of ductile metals
Induction heating has been employed to rapidly raise the temperature of ferrous specimens prior to testing at strain-rates > 10 s". The results show a general tendency for the ductility of a specially-processed pure iron to decrease with temperature over the range tested (20400 C). Based on the experimental data and the results of numerical simulations of the experiment, an empirical fracture m...
