1. 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
2. Characterizing flowability of metal powders
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Powder metallurgy is a growing field with much potential. The core purpose and problem in this work is attempting to describe and understand what and how metal powder properties impact powder flowability. LÄS MER
3. Modelling the influence of porosity on fatigue strength of sintered steels
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : The pores in pressed and sintered components constitute weak points in the material since the stress concentration is larger than the nominal stress there. Therefore, fatigue cracks initiate at the pores. Specifically, it can be assumed that the fatigue cracks initiate at the largest pore in the stressed volume. LÄS MER
4. Property Optimization of PM-gearing
Kandidat-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : The purpose of this bachelor thesis is to design and optimize a powder metal gear through FEM-analyzes. The moment of inertia and weight of the gear shall be reduced at the same time as the demands on tension and bending stiffness are met. LÄS MER
5. A model-based design approach to redesign a crankshaft for powder metal manufacturing
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : A crankshaft is a component which is used to convert a reciprocating movement into rotating or vice versa. Through the past years classical manufacturing techniques did not leave space for a new approach regarding manufacturing this component. LÄS MER
