The magnification is found to be dependent significantly on the value of measurement. The magnification selected is quite different upon the zigzaging.R_S, of fracture surface. The corresponding impact value of material may match the roughness.R_S, of the fracture surface measured only with a magnification properly selected. Using the present measuring method and based on the convension of coefficients R_S and R_L, a fair measurement of the fractal dimension, D_S, for fracture surface may be also obtained. The comparison of R_S value, measured by this method, with the derived ones from the relation between R_S vs R_L, deduced by Wright and Soudani, may further confirm the effectiveness of this method. Moreover, a method may be proposed to estimate R_S by the plating thickness of the fracture surface.(Correspondent: LI Xiaowu, Institute of Metal Reasearch, Chinese Academy of Sciences, Shenyeng 110015) Key words： fracture surface    surface roughness    fractal dimension for surface    magnification    plating thickness      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李小武 田继丰 康雁 王中光 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1995/V31/I19/311 1UnderwoodEE．BanerjiK．ASMMetalsHandbook9thed．OH:MetalsPark,OH,1987;12:1932CosterM,ChermantJL．InternationalMetalsReviews,1983;28:2283GokhaleAM,UnderwoodEE．MetallTrans,1990:21A:11934GokhaleAM．DruryWJ．MetallTrans,1990;21A:12015GokhaleAM,DruryWJ．Materialscharacterization,1993;30:2796MandelbrotBB,PassojaDE,PanllayAJ．Nature,1984;308:7217AlexanderDJ．In:StaussBM,PutatundaSKeds．,QuantitativeMethodsinFractography,ASTMSTP1085,Philodelphia:AmericanSocietyforTestingandMaterials,1990:398UnderwoodEE,BanerjiK,ASMMetalsHandbook9thed．,OH:MetalsPark,1987;12:2119WrighK,KarlssonB．StereolIugosl,1981;3(Suppl1):24710El-SoudaniSM．Metallography,1978;11:247x [1] 宋文硕, 宋竹满, 罗雪梅, 张广平, 张滨. 粗糙表面高强铝合金导线疲劳寿命预测[J]. 金属学报, 2022, 58(8): 1035-1043.
