Journal ArticleDOI
Control of intermetallic compound layers at interface between steel and aluminum by diffusion-treatment
Shigeaki Kobayashi,Takao Yakou +1 more
TL;DR: In this article, the growth mechanism, morphology and mechanical properties of Fe-Al intermetallic compound layers on the surface of carbon steel were systematically evaluated for specimens diffused at temperatures ranging from 873 to 1323 K after hot dip aluminizing.
Journal ArticleDOI
Grain boundary engineering based on fractal analysis for control of segregation-induced intergranular brittle fracture in polycrystalline nickel
TL;DR: In this article, the effect of grain boundary microstructure on the fracture resistance of sulfur-doped polycrystalline nickel was investigated using specimens with different grain boundary macrostructures.
Journal ArticleDOI
Grain boundary engineering for control of sulfur segregation-induced embrittlement in ultrafine-grained nickel
TL;DR: In this article, the brittleness associated with segregation of sulfur to grain boundaries in ultrafine-grained nickel was investigated and grain boundary engineering was applied to control the brittleness.
Journal ArticleDOI
Effects of grain boundary- and triple junction-character on intergranular fatigue crack nucleation in polycrystalline aluminum
Shigeaki Kobayashi,Toshiyuki Inomata,Hiroyuki Kobayashi,Sadahiro Tsurekawa,Sadahiro Tsurekawa,Tadao Watanabe,Tadao Watanabe +6 more
TL;DR: In this paper, the effects of grain boundary and triple junction character on intergranular fatigue crack nucleation were studied in coarse-grained polycrystalline aluminum specimens whose grain boundary microstructures were analyzed by SEM-EBSD/OIM technique.
Journal ArticleDOI
Grain boundary hardening and triple junction hardening in polycrystalline molybdenum
TL;DR: In this paper, the grain boundary and triple junction hardenings in molybdenum with different carbon content were studied in connection with the character and the connectivity of grain boundaries at triple junctions by the micro-indentation test.
