  1. 1. Improved Release Mechanisms for Aerospace Applications

    Kandidat-uppsats, Uppsala universitet/Tillämpad mekanik

    Författare :Baran Hamad; Markus Englund; [2021]
    Nyckelord :release mechanisms; hdrm; split spool initiator; reusable; smart materials; shape memory alloy; sma; pyrotechnic; non-explosive; spacecraft; nitinol; releasemekanismer; hdrm; fästelement; split spool-initierare; återanvändbar; minnesmetall; pyrotekniska; icke-explosiva; rymdfarkost; nitinol;

    Sammanfattning : Hold down release mechanisms (HDRMs) are used for tightly attaching segments of bodies together when it is desired to release them rapidly at some point. When transporting sensitive payloads on launch vehicles, the challenge arises of releasing the fastened segments of the spacecraft without risking damage to the costly equipment. LÄS MER

  3. 2. Intermetallic Compound Formation in Ni-Ti-Fe Powder Mixtures

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Tea Bertilsson; [2018]
    Nyckelord :Phase Evolution; Ni-Ti-Fe System; Intermetallics; Powder Metallurgy; Reactive Sintering; DSC; SEM; EDS; XRD; Technology and Engineering;

    Sammanfattning : The Ni-Ti system has a broad range of applications, in areas as diverse as biomedicine and robotics. This is in large due to the NiTi intermetallic compound, which exhibits the shape memory effect. In addition to this property, the intermetallic compound is also biocompatible, has good mechanical properties and good corrosion resistance. LÄS MER

  4. 3. Evaluation of a new instrument for measuring segmented radial force of SE-stents implemented in the LGF

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Yousef K. Arfaoui; [2018]
    Nyckelord :Technology;

    Sammanfattning : Endovascular surgery is a relatively new, rapidly growing, clinical technique and research area. A new endovascular tool has been developed by Endovascular Development AB, the Liungman Guidewire Fixator (LGF) that secures the distal position of a guidewire. LÄS MER

  5. 4. Development of a Data Transformation Method for a Customized Stent usingAdditive Manufacturing

    Master-uppsats, KTH/Industriell produktion

    Författare :Julius Tepe; [2018]
    Nyckelord :Stent; Nitinol; Additive Manufacturing; customized implants; electron beam melting;

    Sammanfattning : Conventionally manufactured stents are available in uniform sizes and straight forms. These standard products are not suitable for all patients and research indicates that this is the reason for migration of stents in the vessel, and tubular structure in general, after deployment.

  7. 5. Evaluation of a production route for cold-drawn Nitinol wires

    Master-uppsats, KTH/Industriell produktion

    Författare :Sara Olsson; [2016]
    Nyckelord :;

    Sammanfattning : This master thesis has summarized articles and patents found that have been evaluating and optimizing cold-drawing of nitinol wire. The nitinol wire of interest is where the nitinol is used as a core-wire in guidewires. The super-elastic and linear-elastic property of nitinol is attractive in this application. LÄS MER
