Vacuum laser welding of titanium alloys is currently being explored for use in UAVs and military-related fields, but the impact post-weld heat treatment has been seldom studied. In this paper, Ti-6Al-4V alloy was welded by vacuum welding(VLW)with IPG 50kW fiber laser, analyze microstructure properties welds as-welded state post-welding (850°C/2h/FC(FC:furnace cooling)and 980°C/10min/FC+720°C/2h/FC).The results show that weld composed primary columnar crystal (primary β phase) grain boundary...
Ti-6Al-4V (TC4) titanium alloy parts were successfully fabricated by laser melting deposition (LMD) technology in this study. Proper normalizing temperatures presented detailed for bulk LMD specimens. Optical microscope, scanning electron microscopy, X-ray diffraction, and electronic universal testing machine used to characterize the microstructures, phase compositions, tensile properties hardness of TC4 treated using different temperature. The experimental results showed that as-fabricated...
A Nd:YAG laser robot cladding system, which combines a 6-axis robot, powder supply equipment and special delivery nozzle has been used for process. The Stellite 6 + WC mixed were clad on to mild carbon steel plate (SM400B). depth of penetration, cracking behaviour, microstructure, Vickers hardness wear resistance investigated. found increase with volume fraction in the range 0–90%. microstructures layer can be divided into hypoeutectic (0–40%WC) hypereutectic (50–100%WC) regions.
Titanium alloys with high specific strength have widespread applications within the aerospace industry. However, direct fabrication of titanium excellent performance is very difficult using traditional manufacturing techniques. In present work, we adopted advanced laser additive (LAM) technology to fabricate Ti–6Al–4V alloy via addition Niobium (Nb), which result in improvement mechanical properties. The effects Nb additions on microstructure, phase composition, and properties were...
Abstract A bimetallic structure (BS) made of Inconel625 (IN625) nickel-base superalloy with excellent high temperature properties and Ti6Al4V (TC4) titanium alloy a light weight strength has broad application prospects in aerospace engineering. However, the integrated manufacturing IN625/TC4 BS is difficult research topic industry. In this work, laser melting deposition (LMD) technology was used to prepare an without cracks other metallurgical defects by adding Cu/V interlayers. The results...
In the present research, laser robot system was set up for cladding and repairing using a pulsed YAG laser, 6-axis robot, an optical fiber special nozzle powder supply. With this system, SUS304, Colmonoy No 5 FP160 alloy powders were cladded on SM400B steel plate. The shape of clad layer, microstructures performances layer investigated by changing process parameters. A sound with fine microstructure low dilution obtained. Moreover, study technology rapid prototyping performed multi-layers...
