中文名称：金属和合金的腐蚀 环境助生小裂纹生长速率的测定
英文名称：Corrosion of metals and alloys — Measurement of environmentally assisted small crack growth rate
发布日期：2018-11
标准范围
This document specifies a method for determining the growth rate of small surface cracks in an
aqueous environment (including atmospheric exposure) based on measurement of the change in size of
the crack with exposure time.
The methodology can be applied to stress corrosion and corrosion fatigue crack propagation.
It also describes the varied methodologies for the generation of crack precursors including accelerated
generation of single pits.
Industries for whom this document is relevant include power generation (including nuclear), oil and
gas, aerospace and automotive.
