“…PM processes can be used to produce special alloys and metal matrix composites [6]. To achieve homogeneity of reinforcement particle distribution, several methods may be employed, such as a proper choice of the particle size and the use of polar solvents that neutralize the charge on the surface of the particles [7]. Ravichandran et al synthesized Al-based MMCs reinforced with TiO 2 and Gr at different weight percentages and studied the characteristics and strength coefficient during cold upsetting [8].…”

Aluminium metal matrix composites reinforced with TiO2 were synthesized using powder metallurgy route. The compositions such as Al-2.5%TiO2, Al-5%TiO2, Al-7.5%TiO2 and Al-10%TiO2 were milled using ball mill for 1 hour. The green compacts were prepared using 400 kN hydraulic press. The sintering was done by using electric muffle furnace at a temperature of 550°C for 1 hour. Hot extrusion was carried out for the sintered composite samples with suitable punch and die. The mechanical properties such as ultimate tensile strength, yield strength, percentage elongation and hardness have been studied for the hot extruded samples. The microstructures of the extruded composites were analyzed using optical microscope and reported. The high compressive strength was obtained for the Al-5%TiO2 composite.

In material science and engineering the fatigue of metal is quite di cult to deal with and that of welded joint is an even more complex phenomenon. This complexity arises from different main factors: thermal cycles during welding, which will strongly affect the base material and induce residual stresses and distortion, the fusion process with the ller metal leads to heterogeneity to microstructure which will affect or change the original mechanical properties and chemical composition through out of the welded joint. In this study isothermal mechanical fatigue of welded reactor steel has been contemplated. The samples of the welded joint have used in this study is 15H2MFA steel type of VVER-440 reactor pressure vessel operating at Paks Nuclear Power Plant, Hungary. The reactor vessel is made of low-alloy heat resistant steel and austenitic steel with a corrosion-resistant inner (clad) surface. Reactor pressure vessel (RPV) made of 2 ¼ Cr -1Mo-V bainitic steel having a good mechanical strength and creep resistance.
