A編}, month = {}, note = {The objective of present study is to develop a prediction method of residual fatigue crack initiation life of cyclically loaded metallic materials in early stage of its life. Measurements were conducted on a change of intensity of ultrasonic back reflection wave from the material surface under cyclic loading. The microscopic surface observations using optical microscope and atomic-force microscope were also conducted to examine the relation of the change to a fatigue damage of the material. An decrease of the ultrasonic back reflection intensity occurred due to the evolution of fatigue damage at the slip bands. This technique enables one to evaluate the remaining life to the initiation period of fatigue crack at a number of cycles., rights: 社団法人日本機械学会 rights: 本文データは学協会の許諾に基づきCiNiiから複製したものである relation: IsVersionOf: http://ci.nii.ac.jp/naid/110006153352/, text, application/pdf}, pages = {1838--1845}, title = {ステンレス鋼における低サイクル疲労損傷発達の超音波顕微鏡による評価}, volume = {72}, year = {2006}, yomi = {アライ, ヨシオ and ツチダ, エイイチロウ and ナオミ, ヒデアキ} }
