Using intermediate, liquid-forming compositions in the approach focuses on the Si3N4–R2O3 binary, where R2O3 is any (Y,La)2O3–AlN system as additives, fully dense Si3N4 ceramrare-earth oxide (or Y2O3) used singly or severally. After sinics with high strength at high temperature have been tering, this composition forms -Si3N4 and some refractory rareobtained by pressureless sintering. The cerami...

Abstract This study focuses on investigating the relationship between sintering performance and bond layer thickness for hybrid Ag paste consisting of micrometer-sized particles sub-micrometer spherical particles. The surface morphology showed that would contribute to improving densification bonding strength sintered joint. x-ray results indicated quality was achieved when 50 μ m, whereas a thi...

Previously Al-Mg alloy was densified by hot isostatic processing and subsequently consolidated by hydrostatic extrusion. Through this process high strength and high formability nanostructured bulk Al-Mg alloy was fabricated. However, it is important to handle parametric control in powder metallurgical processing in terms of relative density, which is closely associated with its mechanical prope...
