1. Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels
University essay from KTH/MaterialvetenskapAbstract : The development of tool steels for making and shaping other materials requires a better understanding of the material's properties during manufacture. These high-quality steels include many alloying elements, which give increased hardness during tempering. For producing hardened microstructures, austenite generation is essential. READ MORE

2. Investigation of Microstructure and Mechanical Properties in Hot-work Tool Steels
University essay from KTH/MaterialvetenskapAbstract : Hot-work tool steels make up an important group of steels that are able to perform with good strength and toughness properties at elevated temperatures and stresses. They are able to gain this behavior through their alloy composition and heat treatment, which relies on the precipitation of alloy carbides to counter the loss in strength as the tempered material becomes more ductile.

3. WC grain size distribution during sintering of WC-Co cemented carbides
University essay from Lunds universitet/MaterialteknikAbstract : The grain growth of WC in WC-7%Co cemented carbides with Cr-addition was investigated for cemented carbides synthesized from four different raw materials varying in grain size. Cr additions were 4%of the Co binder phase. To investigate the effect of Cr on grain growth two of the raw materials were also synthesized without Cr-additions. READ MORE

4. An Atom Probe Investigation of Addition of Nitrogen in Hot Work Tool Steel
University essay from Lunds universitet/Fysiska institutionenAbstract : Two different hot work tool steels, QRO 90 and QRO 80N were investigated using atom probe tomography. QRO 90 is a commercial alloy while the other QRO 80N is an experimental test alloy. The main composition of QRO 90 is 0.38C-2. READ MORE
