摘要

In this paper many studies have been carried out to ascertain the phenomenon of strain-induced precipitation and coarsening of carbides in AISI H13 hot-work die steel during the tests at 700 ℃. The microstructure of H13 with various loadings was studied to identify the effects of mechanical strain on the evolutionary behavior of carbides. SEM and TEM were used to observe the size and distribution of the carbides of each sample. It was found that the coagulation of carbides is more obvious in mechanical strained samples than that in mechanical strain-free sample which means mechanical strain promotes the precipitation and coarsening of carbides, and these processes are affected by the mechanical strain amplitude. Precipitation is increased by the strain enhanced because of more nucleation sites produced and accelerate the diffusion of solute atoms. Moreover, the results are shown that lower strain rates are more beneficial for precipitation and coarsening of carbides under the same strain because they provide a longer time to nucleate and grow into nuclei.
