研究目的
Investigating the feasibility of using a pure V interlayer in pulsed laser welding to join TC4 Titanium alloy to SUS301L stainless steel without forming brittle Ti-Fe intermetallics.
研究成果
The use of a V interlayer in pulsed laser welding successfully joined TC4 Titanium alloy to SUS301L stainless steel without forming brittle Ti-Fe intermetallics. The joint consisted of two weld zones separated by an unmelted V interlayer, achieving a tensile strength of 587 MPa. The unmelted V interlayer acted as a barrier to mixing and diffusion, improving the joint's mechanical properties.
研究不足
The study focuses on the specific combination of TC4 Titanium alloy and SUS301L stainless steel with a V interlayer. The applicability to other material combinations or welding methods is not explored.
1：Experimental Design and Method Selection:
Pulsed laser welding was chosen with a V sheet as an interlayer to prevent the formation of Ti-Fe intermetallics. The laser was focused near the Ti alloy-V and V-SS interfaces to create two separate weld zones with an unmelted V interlayer in between.
2：Sample Selection and Data Sources:
TC4 Titanium alloy and SUS301L stainless steel plates were used, cleaned with acetone before welding. A 1 mm thick pure V sheet was used as the interlayer.
3：List of Experimental Equipment and Materials:
Nd:YAG pulsed laser with specific parameters, pure V sheet, TC4 Titanium alloy, and SUS301L stainless steel.
4：Experimental Procedures and Operational Workflow:
The laser beam was focused at specific distances from the interfaces to ensure partial melting of the V interlayer, creating two distinct weld zones separated by unmelted V.
5：Data Analysis Methods:
Microstructure analysis, XRD, EDS, and tensile testing were used to evaluate the joint's properties.
