1. 1. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

   University essay from KTH/Materialvetenskap

   Author : Atharva Kotasthane; [2023]
   Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

   Abstract : 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

3. 2. Microstructural, Mechanical and Tribological Studies of Ti-6Al-4V Thin Plates Produced by EBM Process

   University essay from Högskolan Dalarna/Materialteknik

   Author : Onimisi Calistus Sanni; [2019]
   Keywords : Additive manufacturing AM ; Electron beam melting EBM ; Mechanical properties; Tribological behaviour; Microhardness; Micro tensile; Thin sections; Ti-6Al-4V;

   Abstract : The titanium alloy, Ti-6Al-4V, is vastly studied and used in many applications because it has a transformation microstructure, which can be tailored for apt properties that are consistent up to 500°C. Compared to conventional steels, this alloy favours certain applications due to its high specific strength, hardenability, corrosion resistance, biocompatibility and weldability. READ MORE

4. 3. Development of a heat treatment method to form a duplex microstructure of lower bainite and martensite in AISI 4140 stee

   University essay from KTH/Materialvetenskap

   Author : Erik Claesson; [2014]
   Keywords : AISI 4140; 326C; 326F; Isothermal heat treatment; Martensite; Bainite; Molten salt; vacuum furnace; gas quenching.;

   Abstract : Research on bainite and martensite structures has indicated that lower bainite needles have a refining effect on the lath martensitic structure. Lower bainte needles partitions prior austenite grains and will consequently have a refining effect on the subsequent formed lath martensite. READ MORE

5. 4. The modelling of hardenability using mixture density networks

   University essay from Institutionen för systemteknik

   Author : Stefan Glawing; [2004]
   Keywords : Reglerteknik; Hardenability; Jominy; mixture density networks; Neural networks; Reglerteknik;

   Abstract : In this thesis a mixture density network has been constructed to predict steel hardenability for a given alloy composition. Throughout the work hardenability is expressed in terms of jominy profiles according to the standard jominy test. READ MORE
