Re: some qustions of recrystallisation

Dear Bernd

Thank you for your suggestions...actually I just sent the article of my experimental evidences to you...I will adopt your advices to change my code and let you know the results
Regards

Re: some qustions of recrystallisation

Dear Brend I come back with some findings and also other question I have send for you my code privately as a message...I could find out that in my model, considering the heating rate of 100 K/s and very fast austenite reversion coinciding with delayed recrystallization. mobility of each phase has m...

Re: some qustions of recrystallisation

Dear Brend my work is phase transformation through austenite reversion from an initial full martensitic microstructue in the flash heating... by applying flash heating around 100 K/s we have overlap between post started recrystallization and austenite reversion (which can form above Ac1) it is natu...

Re: some qustions of recrystallisation

Dear Brend thank you for your prompt reply maybe I should clarify my work at first: actually, I want to simulate flash annealing at 100K/s heating rate. so, I have single phase cold rolled martensitic microstructure, I have consider martensite as supper saturated ferrite with elliptical shape in gr...

Re: some qustions of recrystallisation

Dear Brend I have a question in case of REX considering for a single phase full martensitic steel (and using Energy thereshold for REX in phase data description, higher amount for min and max REX energy in input grain section and considering 0 as max and min of REX energy plus critical energy for R...

Re: Recrystallisation

Thank you Brend for your prompt reply but, actually my simulated grains are in elliptical shape and there is not minimum and maximum grain radius, there should be curvature for elliptical martensite, but it is not accepted during simulation. unfortunately I could not see straight explanation for ell...

Re: Recrystallisation

Dear Brend I have some question and I will appreciate if you answer to them + my private message to you :) 1) in the case of recrystallization, due to lack of some data for dislocation density on my work (at this level) and same as for stored energy, I have used below item and I have estimated it f...

Re: Geometry of Grain

Dear Brend thank you for your prompt reply...actually, I implemented your advices and here is my code and resulted microstructure :arrow: ...but I still have a problem to simulate cold rolled martensite because I want them all elongated in one direction (X direction) and stick to each other just lik...

Geometry of Grain

Dear Brend I am engaging with an interesting simulation using MICRESS and I need your help in some items...my initial microstructure comprises tempered cold rolled martensite without considering cementite (in this step and for simplifying simulation and reducing time)...It should be noted that I hav...
