要約
応力腐食割れ(SCC)の発生と進展の機構解明に向けて,SCC 亀裂先端に引張応力を加えた状態で走査型透過電子顕微鏡(STEM)観察・分析を実施する手法(Ultra-micro Tensile test system for Crack Tip; UTCT)を開発した.

キーワード    SCC 亀裂先端のミクロ組織,STEM 内引張試験, SEM-TKD

Abstract
To elucidate the mechanism of stress corrosion cracking (SCC) initiation and propagation, an Ultra-micro Tensile test system for Crack Tip (UTCT) was developed to observe and analyze SCC crack tips with a scanning transmission electron microscope (STEM) under tensile stress.

Keywords   SCC crack tip microstructure, tensile testing in STEM, SEM-TKD.
