Effect of Density on the Microstructure and Mechanical Behavior of Powder Metallurgy Fe-mo-ni Steels
The microstructure and mechanical properties of Fe-0.85Mo-Ni powder metallurgy (P/M) steels were investigated as a function of sintered density. A quantitative analysis of microstructure was correlated with tensile and fatigue behavior to understand the influence of pore size, shape, and distribution on mechanical behavior. Tensile strength, Young’s modulus, strain-to-failure, and fatigue stren...
متن کاملSynthesis and liquid phase sintering of TiN/TiB2/Fe–Cr–Ni nanocomposite powder
Nanostructured TiN/TiB2/Fe–Cr–Ni composite powder has been prepared via high energy ball milling. Ti and BN powders are reacted to form uniform mixture of TiN and TiB2 within 2 h of milling by a mechanically activated self-sustaining reaction (MSR). The crystallite sizes of TiN nd TiB2 are about 7 and 16 nm, respectively, after 32 h of milling. Through liquid phase sintering and optimizing the ...
متن کاملAnalyzing and Modelling the Corrosion Behavior of Ni/Al2O3, Ni/SiC, Ni/ZrO2 and Ni/Graphene Nanocomposite Coatings
A study has been presented on the effects of intrinsic mechanical parameters, such as surface stress, surface elastic modulus, surface porosity, permeability and grain size on the corrosion failure of nanocomposite coatings. A set of mechano-electrochemical equations was developed by combining the popular Butler-Volmer and Duhem expressions to analyze the direct influence of mechanical paramete...
متن کاملFabrication of TiC particulate reinforced Ni-50Fe super alloy matrix composite powder by mechanical alloying
Mechanical alloying is a powder metallurgy processing technique involving cold welding, fracturing, and rewelding of powder particles in a high-energy ball mill. In this work, NiFe-TiC composite powders were prepared by mechanical alloying process using planetary high-energy ball mill. The effect of TiC addition by weight percent on the NiFe solid solution formation, grain size, lattice paramet...
متن کاملSimulation of Transient Temperature Field in the Selective Laser Sintering Process of W/Ni Powder Mixture
Selective laser sintering (SLS) is an attractive rapid prototyping and manufacturing (RP&M) technology as well as two-component metal powder has high melting pointer, high mechanical properties and high wear resistance. Hence, it’s meaningful to analyze its temperature field distribution and dynamical evolution rule in sintering process. A three-dimensional transient finite element model of SLS...
