Eutectic composition titanium metal matrix composites for laser powder bed fusion via surface remelt analyses

چکیده
Ti-based metal matrix composites (MMCs) represent a material class with highly desired performance for the aerospace industry, but implementation has been hindered by poor processability. It is now being realised that MMCs can be formed in situ through exploitation of rapid cooling rates laser powder bed fusion, and targeting invariant reaction compositions to minimise propensity solidification cracking. We perform line scans surface remelts arc-melted Ti–0.38C, Ti–1.67B, Ti–8.5Si Ti–32.5Fe wt-% eutectic assess potential amenability fusion (LPBF) process at low cost as well determining nanostructure hardness properties. The results indicate are amenable LPBF may outperform conventional alloys.

Evaluation of titanium carbide metal matrix composites deposited via laser cladding
Metal matrix composites have been widely studied in terms of abrasion resistance, but a particular material system may behave differently as particle size, morphology, composition, and distribution of the hardening phase varies. The purpose of this thesis was to understand the mechanical and microstructural effects of combining titanium carbide with 431 series stainless steel to create a unique...
متن کاملSome aspects on designing for metal Powder Bed Fusion
Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. This thesis is about some aspects of when and how to Design for Additive Manufacturing (DfAM) when using the PBF method i...
متن کاملFunctionalization of Biomedical Ti6Al4V via In Situ Alloying by Cu during Laser Powder Bed Fusion Manufacturing
The modern medical industry successfully utilizes Laser Powder Bed Fusion (LPBF) to manufacture complex custom implants. Ti6Al4V is one of the most commonly used biocompatible alloys. In surgery practice, infection at the bone-implant interface is one of the key reasons for implant failure. Therefore, advanced implants with biocompatibility and antibacterial properties are required. Modificatio...
متن کاملLaser Ultrasonics for Non-destructive Evaluation of Metal Matrix Composites
Laser ultrasonics is based on the generation of elastic waves by transient surface heating or ablation with short laser pulses. These waves are traveling through the sample, are reflected and scattered at interfaces and the backside of the sample. To realize an ultrasound measurement device we have used either an interferometer coupled to a continuous wave laser (contact-free) or the sample was...
