The aim of this study was to investigate the weldability high-density polyethylene sheets via heat assisted friction stir welding and effect process parameters on microstructure mechanical properties welded plates. under were included pin rotational speed, transverse speed tool shoulder temperature. Tensile bend tests done in order evaluate behavior material. results showed that plates could be with joint characteristics similar base This accomplished by operating a high temperature as well...

Due to the higher production cost of monolithic carbide tools as well their brittle nature, cemented carbides such WC-Co are frequently joined tool steel. To overcome joining complications that arise due notable differences in thermal expansions between components and poor wettability, various investigators have used copper-based silver-based filler metals dissimilarly braze steels. However, researchers do not agree about selection material. This research investigates use pure copper, brass,...

In this study, austenitic 316L stainless steel produced by Selective Laser Melting (SLM) was reinforced with SiC nanoparticles using Friction Stir Processing (FSP). The microstructure and mechanical properties of the resulting nanocomposite were experimentally investigated, multiscale finite element modeling performed Mori-Tanaka homogenization method to predict its macroscopic based on microstructural interactions. SLM-fabricated samples via FSP 10 vol% subjected tensile tests. Results...
