چکیده
The present investigation is dealing with the evolution of simultaneous dynamic and metadynamic recrystallization (DRX)& (MDRX) phenomena by physical simulation for a 4-strock hot compression process, where flow curves were presented for each stroke. The primary alloy is a penetrator steel containing 0.3% C in addition to some Cr, Mo, Ni and 1.63 W. Calculated grain size after the onest of DRX & occurrence of MDRX decreases continuously with the increase of cumulative strain reaching to 0.289 µm. However, Electron Backscatter Diffraction (EBSD) investigation established that 99% of the grains, after the last compression stroke, were detected as <1.0 μm, with an average grain size 0.31 μm. Microstructure after simulation presents fine lath martensitic structure, coexisting with Cr-W carbides, which are crammed at the inter- martensite laths. Furthermore, 56% of the grains showed grain boundaries misoriention creating High Angle Grain Boundaries (HAGBs), which are promoting MDRX. The flow curve of each stroke definitely contains two complementary microstructure events, namely a DRX , and a MDRX phenomenon, where the peak stress (σp) of DRX is inversely proportional to the mean temperature of stroke.
