Production and microstructural investigation of Al-nano TiB2 composite produced by powder metallurgy technique
Automotive and aerospace industries are required to light materials which have high properties. This causes to reduce production cost and fuel consumption. One of these advanced materials that have been attracted at these decades is particulate metal matrix nanocomposites. These materials have a combination of ductile matrix alloy properties and ceramic reinforcement nanoparticles. Powder metal...
متن کاملDetermination of Transformation Induced Heat Transfer Coefficients in Mechanical Properties of Powder Metallurgy Steels
Powder metallurgy has been used for the manufacture of fully dense, which have not reacted composites consisting of a matrix of copper containing 50 -60 vol% particles with negative thermal ZrW2O8 expansion. On cycling between 25 and 300°C, the compounds showed coefficients thermal expansion which varies rapidly with temperature and significantly larger than expected by theory. Improvements in ...

متن کاملEffect 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 کاملPorous, Superelastic NiTi Produced by Powder-Metallurgy
Near-stoichiometric NiTi was foamed in the solid state at elevated temperatures through creep expansion of highpressure argon pores previously entrapped during powder consolidation. A sample with 17% porosity was found to be superelastic up to a compressive stress of 800 MPa.
