ISO 9042:2024 钢 用点网格统计估算成分体积分数的点计数方法

标准编号：ISO 9042:2024

中文名称：钢 用点网格统计估算成分体积分数的点计数方法

英文名称：Steels — Point counting method for statistically estimating the volume fraction of a constituent with a point grid

发布日期：2024-04

标准范围

该文件规定了一种点计数方法，用于借助于点网格通过钢的微观结构统计地估计成分的体积分数。它适用于可清楚识别的成分。默认情况下，计数是手动执行的，但可以是计算机辅助的或由经验证的计算机算法代替。笔记？在本文中，术语“成分”可以表示相以及由两个或更多个相组成的显微组分。

This document specifies a point counting method for statistically estimating the volume fraction of a constituent through the microstructure of a steel by means of a point grid.

It applies to constituents which are clearly identifiable.

By default, counting is performed manually, but can be computer assisted or substituted by validated computer algorithms.

NOTE            In this document, the word "constituent" can designate a phase as well as a micrographic constituent composed of two or more phases.
