1. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. LÄS MER
2. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER
3. Modelling Gas Flow Behaviour in Gas Atomizer
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

4. Powder Rheology within AM production : Evaluating Compressibility, Permability, & Aeration for 316L Powders Within SLM Processes
M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Additive manufacturing with the use of metals have been a steadily increasing field, being able to create products with a higher degree of complexity than traditional processing techniques. SLM is a popular AM process that uses metal powder as feedstock, and one of the key components of this process is the powder rheology. LÄS MER
5. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible as of today to be able to remove all of them. The inclusions are categorised into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of nonmetals: slag, mold). LÄS MER
