Exploring Metal-Metal Composites: A Study on AA5083 Matrix-Cr Particles Reinforced Composites.

The objective of this study is to develop chromium-reinforced metal-metal composites utilizing an AA5083 aluminum alloy matrix through powder metallurgy while also examining their properties. Samples were produced by incorporating varying quantities of chromium (5%, 10%, and 15% by weight) into the AA5083 matrix. In order to ensure a uniform distribution of chromium particles, the powders were blended in a ball mill and subsequently hot-pressed at 500 °C under 500 MPa for a period of two hours in an argon atmosphere.

Optimization of Dry Sliding Wear in Hot-Pressed Al/BC Metal Matrix Composites Using Taguchi Method and ANN.

The presented study investigates the effects of weight percentages of boron carbide reinforcement on the wear properties of aluminum alloy composites. Composites were fabricated via ball milling and the hot extrusion process. During the fabrication of composites, BC content was varied (0, 5, and 10 wt.

Effect of the usage of Er,Cr:YSGG laser with and without different remineralization agents on the enamel erosion of primary teeth.

The aim of the present study was to evaluate the effects of different remineralization agents associated with erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) (0.5 W power, 20 Hz frequency, 60% water, 40% air, 25 mJ pulse energy, 8.84 J/cm fluence, 60 μs pulse duration, 600 μm tip diameter, and an approximate 1-1.
