The basic aim of this work is to perform characterization of the powder obtained from surface of waste plastic brick which in turn provides a base to study the physical and chemical composition of bricks made from waste plastic bags and sand (Plastic bricks). The powder used for characterization was obtained from the surface of waste plastic bricks by scratching the surface of bricks with knife-like stainless-steel instruments. Before characterization, this powder was strained through a double layer strainer (mesh number 325, pore size 44 microns) to obtain fine powder particles. This fine pow

Laser cutting technology is one of the basic approaches used for thermal processing of parts fabricated from almost all engineering materials. Various types of lasers are utilized in the industry with different attendant gases such as nitrogen or argon. When the laser beam interacts with a metal surface, the area underneath is heated to the melting point. This liquid or vaporized metal is ejected from the kerf area to the surrounding atmosphere by attendant gas and becomes undesirable waste in the form of powder.

To interpret highly superimposed diffraction patterns, the Rietveld method together with conventional X-ray powder diffraction techniques were carried out on a series of heat-treated weldments of cast super duplex stainless steel. High temperature processing of this type of alloys causes embrittlement and loss of corrosion resistance owing to precipitation of intermediate phases, principally sigma-phase. The annealing processing of the samples proceeded at temperatures in the range of 800–950 °C for periods of time from 1 to 96 h. This procedure permitted an accurate quantification of the micr
