1. Image Analysis Methods For Additive Manufacturing Applications
Master-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)Sammanfattning : There is an upsurge of research interest on Ni-based superalloys additively manufactured (AM) in aerospace sectors. However, achieving the accuracy and quality of the AM part is a challenging task because it is a process of adding material layer by layer with different process parameters. LÄS MER
2. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. LÄS MER
3. Study of the effect of process parameters in laser blown powder with superalloys : Varying laser power and scanning speed, analyzing material properties
Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Sammanfattning : Additive manufacturing (AM) is a growing process interesting many companies in many industries. Thereare multiple processes within the familty of AM, but this study focuses on laser blown powder (LBP). LBP involves a laser beam focused on the substrate with powder being blown into the laser beam. LÄS MER
4. Evaluation of Heat Treatments for the Nickel-Based Superalloy Haynes® 282® Manufactured by Selective Laser Melting : A Study Based on Microstructural Examinations and Mechanical Testing
Master-uppsats, Linköpings universitet/KonstruktionsmaterialSammanfattning : Nickel-based superalloys have a wide range of applications, mainly in gas turbines for power generation and aircraft propulsion. They are superior to competing alloys in maintaining excellent mechanical properties for extended durations at extreme temperatures and loads, all while resisting corrosion and oxidation. LÄS MER
5. Design of Experiment for Laser cutting in Superalloy Haynes 282
Master-uppsats, Karlstads universitet/Science, Mathematics and Engineering Education Research (SMEER)Sammanfattning : This project aims to investigate the effect of varying different laser cutting parameters on the laser cut surface. The parameters that were varied were cutting speed, beam effect, gas pressure and focal point. LÄS MER
