Autor: GAO Le, ZHAO Bin, ZHOU Xiangwen, LI Zhenlei, SONG Dazhao, YAN Pengfei, TIAN Xianghui

Publikováno v: Meikuang Anquan, Vol 53, Iss 2, Pp 219-225, 233 (2022)

Selecting reasonable coal pillar size is the premise of success and safety of gob side entry driving. Taking 30503 working face of a coal mine as the background, the reasonable size of narrow coal pillar in gob driving roadway under the condition of

Experimental Investigation on the LCF Behavior Affected by Manufacturing Defects and Creep Damage of One Selective Laser Melting Nickel-Based Superalloy at 815 °C

Autor: Xian-Feng Ma, Cheng-Li Dong, Jia Huang, Fencheng Liu, Xiaoan Hu, Yun Jiang, Gao-Le Zhao

Publikováno v: Acta Metallurgica Sinica (English Letters). 33:514-527

Uniaxial tensile tests and stress-controlled low-cycle fatigue (LCF) and creep–fatigue interaction (CFI) tests of Inconel 625 alloy manufactured by selective laser melting (SLM) were performed at 815 °C in air environments. The microstructure was

Microstructure and mechanical behavior of Inconel 625 alloy processed by selective laser melting at high temperature up to 1000 °C

Autor: Gao-Le Zhao, Fen-Cheng Liu, Xiaoan Hu, Wei-Xiong Liu

Publikováno v: Rare Metals. 39:1181-1189

Mechanical behavior of Inconel 625 alloy manufactured by selective laser melting (SLM) was experimentally studied. Tensile tests were performed at various temperatures (20, 540, 760, 815, 870, 950 and 1000 °C). The microstructures and fracture mecha
