In order to achieve the microstructure homogeneity at a lower temperature and improve mechanical properties, novel post heat treatment was introduced Inconel 718 fabricated by laser direct energy deposition (LDED), means of δ aging + solution treatment. The analysis shows that fully precipitation phase in LDED superalloy can "cut" long strip Laves into small pieces. According with treated 1020 °C for 30 min, only tiny particle remained. equilibrium volume fraction after is about 1%, which...
In this study, the effect of Al addition on microstructure and microhardness Inconel 718 superalloy fabricated by laser additive manufacturing (LAM) was studied. The had little grain morphology orientation, but segregation Nb element intensified with increase content, which promoted formation Laves phase in inter-dendritic region. After HSDA (Homogenization + Solution Double aging) heat treatment, precipitation δ at boundaries changed from cross needle-like to rod-like, same time, more...
Laser cladding repair technology is valued for its ability to of damaged parts with high performance. However, there are so many parameters affect the quality that it takes a lot work determine optimal parameters. In this article, variety were combined as dimensionless heat input (Q∗), and effect Q∗ on microstructure mechanical properties 300M steel repaired samples studied. Results showed increase Q∗, affected zone transformed from tempered martensite low bainite. The untempered small...
The composite technology based on friction stir processing (FSP) can enhance the strength of Al alloys while retaining original toughness and ductility alloys, thus achieving an improvement in overall performance composites. Ni/Al composites were prepared three typical matrixes by optimized FSP, effect situ generated intermetallic compounds strengthening different substrates during FSP was investigated. It found that reinforcing phase mainly generation Al3Ni compound using energy dispersive...
Laser remelting can be used not only to improve the metal surface structure, but also repair defects. 34CrNiMo6 belongs European standard high strength alloy structural steel. It has been widely in manufacture of large-size shaft parts which are prone defects such as cracks and wear during service. This study proposed a method for these by laser filled block then performed heat treatment. The microstructure, m9icrohardness tensile repaired sample heat-treated were analyzed using scanning...
Dissimilar Al–Li alloys (2198 and 2060) were laser welded without the addition of filler material. The effects welding parameters on formation joints, microstructure evolution, solute segregation, porosity their relationships with mechanical properties joint investigated. It was found that reducing weld heat input can effectively prevent grain coarsening, while decreasing tendency for hot cracking, thereby enhancing joint. dissolution precipitates such as T1 phase θ′ in base metal,...
