摘要

本文的目的是理论计算在600 ~ 1100℃温度范围内铁空位中氮气压力引起的机械应力及其对高温粘性流动膨胀现象的影响。定量的方法是理论性的,并基于对文献中报道的实验数据的分析。生成了与变量相关的两个方程:随时间膨胀指数和氮压应力。这两个变量都以递增的方式描述,并在99%的置信水平上显著相关。这些方程包括从以前的论文中得到的铁素体(Feα)为621,2 Kgf/mm2和奥氏体(Feγ)为727,6 Kgf/mm2的应力值。将这些值与商业样品的平均样品冷压缩强度相对比时的总体效果,随着相应的降低程度而变化,该参数的最终值在35.2和69.6 Kgf/mm2之间。

Effects of thermoviscous flow and mechanical stresses on nitrogen desorption during iron transformation
The objective of this paper is a theoretical calculation of the mechanical stresses due to nitrogen pressure in an iron vacancy in the temperature range of 600 to 1100 °C and its effect on the swelling phenomenon associated with the high-temperature viscous flow. The method for quantification is theoretical and based on the analysis of experimental data reported in the literature. Two equations related to the variable were generated: swelling index with time and the stress due to nitrogen pressure. Both the variables are described in increasing ways and correlated significantly at the 99% confidence level. The equations include the value of stresses obtained from previous papers for ferrite (Feα) of 621, 2 Kgf/mm2 and for austenite (Feγ) of 727, 6 Kgf/mm2. The overall effect when opposing these values to the average sample cold compression strength of commercial samples, which varies with the corresponding degree of reduction, the final value of this parameter results in the range of 35.2 and 69.6 Kgf/mm2.

期刊介绍: Ahora que el fenómeno de la disciplinarización institucional está cada vez más marcado, Athenea Digital promueve la reflexión interdisciplinar en la tradición de las ciencias humanas y sociales. La revista aborda los fenómenos sociales contemporáneos en sus múltiples dimensiones (política, económica, cultural, comunicacional...) y valora la reflexión rigurosa sobre la articulación entre los diferentes dominios de la actividad humana. El principal objetivo de la revista es potenciar el diálogo y la innovación en los estudios sociales y culturales.
