The loss of mechanical properties in heat treatable aluminum alloys categories during arc fusion welding processes is a critical issue, which limits the direct application in contrast to different post-treatments methods. This work involved a strategy for the novel and distinctive formation of fillers using 3-mm-diameter (AA6061) tubes having MWCNTs and TiO2 nanoparticles coating on the inner surface...
In this study, mechanical and physical properties of hybrid composites were analyzed by using a data acquisition technique like artificial neural networks. Matlab software was used to examine the effects of test parameters on infiltration temperature and pressure. Bending strength, hardness and density of hybrid composite were affected in neural network training and test. Firstly, training set was...
This study is focused on the role of hydroxyapatite (HA) nanoparticles and graphene oxide (GO) nanoplates on the flexural and compression properties of epoxy-based hybrid nanocomposites. In the first step, epoxy-based hybrid nanocomposites were reinforced by different HA nanoparticles and GO nanoplates up to 7 wt% and 0.5 wt%, respectively. Filler’s weight fractions that used as design parameters...
In this study, aluminium hybrid composites were fabricated by reinforcing eco-friendly agrowaste, groundnut shell ash and boron carbide using squeeze casting method. Groundnut shell ash and boron carbide were added in ratios of 2.5:7.5, 5:5 and 7.5:2.5 percentages by weight. The impact on mechanical properties namely density, hardness, tensile strength, impact strength was studied, and the results...
Aluminium matrix composites (AMCs) have great potential for critical applications within aerospace, automotive, defence, marine, agriculture and nuclear engineering sectors. The composite materials are very attractive because of their good balance between lightweight versus high strength and machinability. Depending on the particular application, these properties can be further enhanced by adding...
In the present work is studied the influence of titanium dioxide on the microstructure and mechanical properties of submerged arc weld P91 steel weldment. To manipulate the chemical composition of the weldment, the titanium dioxide (TiO2) powder was added with fresh welding flux in various proportions (2.5–12.5%). The results of optical emission spectroscopy test showed that Ti wt% is systematically...
