奥氏体的稳定化是一种经常发生的现象，使得从奥氏体到马氏体的转变变得困难。分析特定因素对奥氏体稳定化的影响的直接方法是通过其对马氏体开始温度M-S的影响。本工作概述了使用人工神经网络来模拟基于其化学成分和奥氏体晶粒尺寸的工程钢的M-S。结果集中于阐明钢中合金元素在奥氏体稳定中的作用，包括不太常见的元素如钒和铌，以及奥氏体晶粒尺寸。此外，物理解释的结果。
The stabilisation of austenite, a phenomenon that frequently occurs, renders the transformation from austenite to martensite difficult. The straightforward method of analysing the effect of a specific factor on the stabilisation of austenite is through its influence on the martensite start temperature M-S. The present work outlines the use of an artificial neural network to model the M-S of engineering steels based on their chemical composition and austenite grain size. The results are focused on elucidating the role in the stabilisation of austenite of alloying elements in steels, including less common elements such as vanadium and niobium, as well as the austenite grain size. Moreover, a physical interpretation of the results is presented.
