Journal ArticleDOI
Influence of aging temperature on strength and toughness of laser-welded T-250 maraging steel joint
TL;DR: In this article, the effect of aging temperature on microstructures and mechanical properties of laser-welded T-250 maraging steel joints was investigated, and it was shown that the Ni 3 (Ti, Mo) precipitate and reverted austenite are the critical factors influencing the strength and toughness of welded joints.
Journal ArticleDOI
Effect of post-weld heat treatments on strength and toughness behavior of T-250 maraging steel welded by laser beam
TL;DR: In this article, the strength and toughness behavior of T-250 maraging steel welded by laser beam under different approaches of three post-weld heat treatments, i.e., aging (A), solutionizing+aging (SA), and homogenizing+solutionizing +aging (HSA), were investigated.
Journal ArticleDOI

TL;DR: In this paper, the tensile properties of 2219-T8 TIG welded joints were improved by adjusting the weld geometry using multi-pass welding with swing, and the effects of weld geometry on the properties of joint were investigated.
Journal ArticleDOI
Evolution behavior of liquid film in the heat-affected zone of laser cladding non-weldable nickel-based superalloy
Zhenlin Zhang,Yue Zhao,Yue Zhao,Jiguo Shan,Jiguo Shan,Aiping Wu,Aiping Wu,Yutaka S. Sato,Shun Tokita,Kota Kadoi,Hiroshige Inoue,Huaipeng Gu,Xin Tang +12 more
TL;DR: In this article, the authors studied the metallurgical evolution behavior of liquid film and liquefaction cracking mechanisms and showed that a kind of uncommon Ni21Hf8 phase was found in the incipient melting regions (IMR) of the intergranular region.
Journal ArticleDOI
The role of the pulsed-wave laser characteristics on restraining hot cracking in laser cladding non-weldable nickel-based superalloy
Zhenlin Zhang,Zhenlin Zhang,Yue Zhao,Yue Zhao,Yang Chen,Yang Chen,Zhen Su,Zhen Su,Jiguo Shan,Jiguo Shan,Aiping Wu,Aiping Wu,Yutaka S. Sato,Huaipeng Gu,Xin Tang +14 more
TL;DR: In this article, a paraxial powder-feeding system by employing a quasi-continuous fiber laser machine was established to repair non-weldable nickel-based K447A alloy.
