1. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels
University essay from KTH/MaterialvetenskapAbstract : 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. READ MORE

2. DILATOMETRIC EVALUATION OF SOME CRITICAL PHYSICAL PROPERTIES OF OT75 AND OT101 STEEL GRADES
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Due to its hardness, martensite, perhaps, is the most desirable structure, but at the same time, martensite is very brittle. Balancing between hardness and brittleness is a challenge that steel manufacturers must deal with it. To decrease brittleness and to solve this problem, designers purposely temper the steel. Heat treatment, e. READ MORE

3. Combined CALPHAD and Machine Learning for Property Modelling
University essay from KTH/MaterialvetenskapAbstract : Techniques to improve the speed at which materials are researched and developed has been conducted by investigating the machine learning methodology. These techniques offer solutions to connect the length scales of material prop- erties from atomistic and chemical features using materials databases generated from collected data. READ MORE

4. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing
University essay from KTH/MaterialvetenskapAbstract : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. READ MORE

5. Thermodynamic modelling ofmartensite start temperature in commercial steels
University essay from KTH/MaterialvetenskapAbstract : Firstly, an existing thermodynamic model for the predicting of martensite start temperature of commercial steels has been improved to include more elements such as N, Si, V, Mo, Nb, W, Ti, Al, Cu, Co, B, P and S and their corresponding composition ranges for Martensitic transformation. The predicting ability of the existing model is improved considerably by critical assessment of different binary and ternary systems i. READ MORE
