  1. 1. Characterization of Laser Deposited Alloy 718

    Master-uppsats, KTH/Materialvetenskap

    Författare :Pengcheng Cao; [2016]
    Nyckelord :Additive; Deposition; Alloy 718;

    Sammanfattning : Additive Manufacturing (AM) is a method of producing three-dimensional objects using additive processes. It allows great flexibility in the processes and reduces the design-to-production time. Laser Metal Deposition (LMD) is one of AM methods under development and is based on the deposition technology.

  3. 2. Homogenization of Precipitation Hardening Nickel Based Superalloys

    Master-uppsats, Materialvetenskap

    Författare :Olutayo Adegoke; [2012]
    Nyckelord :;

    Sammanfattning : Allvac 718 Plus and Haynes 282 are relatively new precipitation hardening nickel based superalloys with good high temperature mechanical properties. In addition, the weldability of these superalloys enhances easy fabrication. LÄS MER
