【摘要】：建立了有限元-有限體積耦合的熱處理流場、溫度場、組織場、應力場數(shù)值模型,并采用真空高壓氣淬工藝對該模型進行了驗證。模擬結果與實測不同位置的冷卻曲線和顯微組織吻合較好。本研究擴展了熱處理模擬的求解域,克服了傳統(tǒng)淬火模擬需預先獲得淬火介質換熱系數(shù)的局限。模擬可獲得工件熱處理后的顯微組織分布和殘余應力分布,進而為熱處理工藝的制定提供參考。
[Abstract]:A finite element finite volume coupled heat treatment flow field, temperature field, microstructure field and stress field are established, and the model is verified by vacuum high pressure gas quenching process. The simulation results are in good agreement with the cooling curves and microstructure measured at different locations. This study extends the solution domain of heat treatment simulation and overcomes the limitation that the traditional quenching simulation needs to obtain the heat transfer coefficient of quenching medium in advance. The microstructure distribution and residual stress distribution of workpiece after heat treatment can be obtained by simulation.
