Effect of networked Cu-rich ferrite phase on proof stress and ultimate tensile strength of sintered bodies of Fe–Cu hybrid-alloyed steel powder with graphite
Autor: Y. Shigeta, Masatoshi Aramaki, Yoshifumi Ikoma, K. Ashizuka, Yukiko Ozaki
Publikováno v: Powder Metallurgy. 64:134-141
To improve the yield strength of powder metallurgy steel, this work investigated the effect of a Cu-rich networked phase. Mixtures of 0.7% graphite and Fe–3% Cu hybrid-alloyed steel powders, compos...

Synchrotron X-ray laminography was used to examine the time-dependent evolution of the three-dimensional (3D) morphology of micropores in sintered iron during the tensile test. 3D snapshots showed that the networked open pores grow wider than 20 µm

Effects of Nitriding-Quenching and Carburizing-Quenching on Wear Properties of Industrial Pure Iron
Autor: Osamu Furukimi, Muhammad Kozin, Masatoshi Aramaki, K. Yoshida
Publikováno v: HTM Journal of Heat Treatment and Materials. 73:131-143
The wear properties of industrial pure iron treated by nitriding-quenching and carburizing-quenching were investigated. Both the nitrogen martensite and carbon martensite produced by each treatment exhibited the same high degree of wear resistance. T

Elucidation of pore connection mechanism during ductile fracture of sintered pure iron by applying persistent homology to 4D images of pores: Role of open pore
Autor: Shinji Munetoh, Isshin Ando, Yukiko Ozaki, Akihisa Takeuchi, Kyosuke Hirayama, Masatoshi Aramaki, Yasutaka Mugita, Takeshi Tsuji, Fei Jiang, Masayuki Uesugi
Publikováno v: Materials Science and Engineering: A. 828:142112
4D pore configurations including an open pore were visualized by synchrotron X-ray laminography during the ductile fracturing process and then interpreted quantitatively using persistent homology (PH), a topological measure. In particular, this study

Void nucleation behavior of single-crystal high-purity iron specimens subjected to tensile deformation
Autor: Masatoshi Aramaki, Shinji Munetoh, Chatcharit Kiattisaksri, Osamu Furukimi, Yuji Takeda, Masaki Tanaka, Satoshi Oue
Publikováno v: Materials Science and Engineering: A. 701:221-225
Void nucleation plays an important role for determining local deformation properties of ductile materials. In this study, the void nucleation behavior of single-crystal iron was examined in tensile tests. Two micrometer-size single crystals having a
