为了支持加速新材料开发和鉴定的新方法，precpicalc TM软件已经开发成为一种高效、高保真的3D多相沉淀模拟器，该模拟器基于计算热力学和多组分扩散成核和结合界面耗散的生长模型。在联邦政府资助的一个主要项目下进行了广泛的验证，该软件已成功地应用于IN100镍基航空涡轮盘合金在复杂的商业热处理工艺下的多尺度（从nm到µm）、多模态γ -微观结构发展的精确和快速模拟。将precpicalc与有限元传热模拟和强度模型相结合，可以准确预测性能变化，从而加快工艺优化和设计最小性能的概率建模。
In support of a new methodology of accelerated development and qualification of new materials, the PrecipiCalc TM software has been developed as an efficient, high-fidelity 3D multiphase precipitation simulator grounded in computational thermodynamics and multicomponent diffusional nucleation and growth models incorporating interfacial dissipations. With extensive validation under a major federally sponsored program, the software has been successfully applied to the accurate and rapid simulation of multiscale (from nm to µm), multimodal γ � microstructure development in IN100 Ni-based aeroturbine disk alloys under complex commercial heattreatment processing. Integration of PrecipiCalc with FEM heat transfer simulation and a strength model has demonstrated accurate prediction of property variation for accelerated process optimization and probabilistic modeling of design minimum properties.
