Structure and properties of -carbides in duplex lightweight steels
κ-carbide in lightweight steel is studied. Its thermal stability, crystal morphology, orientation relationship, degree of lattice misfit and mechanical properties are measured experimentally. The mechanisms for the microstructural evolution of κ-carbide are considered based on the crystal structure, lattice misfit, element diffusivity, and solute partition. The hard γ/κ grain and ductile α+κ gr...

متن کاملSolidification Phenomena and Properties of Some Cast Tool Steels
The freezing process. microstructures and phase relationships in some experimental cast tool steels have been investigated and developed under the various solidification conditions. Experimental steels were based on AISI M2 and M10 grades high speed steels. Addition of carbide forming elements such as niobium and titanium with and without extra carbon were made to the molten bath of the base st...
متن کاملTi-Cr-N Coatings Deposited by Physical Vapor Deposition on AISI D6 Tool Steels
In this study, physical vapor deposition (PVD) Ti-Cr-N coatings were deposited at two different temperatures 100 and 400ºC on hardened and tempered tool steel substrates. The influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and Young’s modulus were evaluated. Phase compositions were st...
متن کاملThermal-Shock Resistance and Fracturestrength Behavior of Two Tool Carbides
The thermal-stress resistance and fracture-strength behavior of TIC and WC after severe thermal shocking were investigated. The damage-resistance parameter, (K1c/af)2, for both carbides was determined over a wide range of loading rates and temperatures. The fracture-strength behavior of these two carbides in the quenching temperature range of 25" to 800°C follows Hasselman's model for an instan...
