本文对扩散控制变换（DICTRA）软件进行了概述。DICTRA是一个用于多组分合金扩散模拟的工程工具。模拟是基于多组分扩散和热力学数据，两者都是通过分析和评估实验信息得到的。这样，一旦获得基础数据，就可以对许多不同的案例进行研究。DICTRA不是一个完整的模拟工具，因为只能处理可以转换为一个空间变量的几何形状，但可以解决许多实际问题。该程序包含了几种不同的模型，本文对此进行了讨论。每个模型都有自己的应用，并给出了最近模拟的几个例子，以说明特定模型的用法。
In the present paper, a general survey of the diffusion-controlled transformations (DICTRA) software is given. DICTRA is an engineering tool for diffusion simulations in multicomponent alloys. The simulations are based on multicomponent diffusion and thermodynamic data, both obtained by analyzing and assessing experimental information. This allows for many different cases to be studied as soon as the underlying data are available. DICTRA is not a complete simulation tool because only geometries that can be transformed into one space variable can be treated, but many well posed problems of practical interest may be solved. The program contains several different models, which are discussed in the present paper. Each model has its own applications and several examples from recent simulations are given in order to demonstrate the usage of the particular models.
