The heat treatment processes are applied to the die steels including deep cryogenic treatment [ 6 , 7 , 8 ], spheroidizing annealing [ 9 , 10 , 11 ], austenitizatio solution [ 12 , 13 ] and sp.info Behavior of Oil Well Cement-Water Slurriesof 0.05%, 0.1%, 0.2% and 0.4% of cement weight. The mechanical, thermal, and microstructural of CNF-cement composites were studied by Mejdoub et al [14], in which CNFs were produced by homogenization from eucalyptus pulp. The results showed that most measured properties (i.e., mechanical, thermal, and microstructural) were significantly improved.sp.info Microstructural Characterization and Mechanical Properties

  • AbstractIntroductionMaterials and Experimental ProceduresResults and DiscussionConclusionsAcknowledgmentsDynamic plastic deformation (DPD) achieved by multipass hammer forging is one of the most important metal forming operations to create the excellent materials properties. By using the integrated approaches of optical microscope and scanning electron microscope, the forging temperature effects on the multipass hammer forging process and the forged properties of Ti-6Al-4V alloy were evaluated and the forging samples were controlled with a total height reduction of 50% by multipass strikes from 925°C to 1025°CMicrostructural evolution and grain refinement

Constrained groove pressing (CGP) is one of the SPD techniques that has gained prominence recently. However, the efficacy of the method in terms of homogeneity of microstructure and properties has not been well explored.sp.info Microstructural Control and Elevated Temperature Thermal treatments designed to increase the precipitation of the δ phase, minimize the formation of NbC, and increase the overall microstructural homogeneity were performed on SLM material. The changes were evaluated based on the same mechanical tests that revealed environmental sensitivity and were found to improve elevated temperature ductility.
