... on a commercial MIM production line has been carried out. Steel-based feedstocks gathering on titanium green parts diffused into the titanium giving rise to liquid phase sintering, which disfigured the appearance of the titanium products. The trial production of titanium parts on a steel-based mass production...

... and brittle material, sintered tungsten carbide. The findings suggest that the same concept can be applied for the ductile cutting of other hard and brittle materials. brittleness cutting tools ductility finishing machining sintering tungsten compounds ultrasonic machining vibrations...

... prepared under a series of sintering conditions. The contents of Si 3 N 4 powder ranging between 0 wt % and 15 wt % and the sintering temperature were varied in the experiments in order to understand the dependence of densification kinetics and changes in properties on these process parameters...

...M. Barletta; A. Gisario; S. Guarino; G. Rubino The manufacture of open cell metal foams by dissolution and sintering process (DSP) is the matter of the present work. Aluminum foams were produced by mixing together carbamide particles with different mesh sizes (i.e., space-holder) and very fine...

...John E. Wentz; Shiv G. Kapoor; Richard E. DeVor; N. Rajagopalan In this paper, the fouling of sintered α -alumina membranes by an uncontaminated semisynthetic metalworking fluid (MWF) is addressed. Experimental evidence of the form of flux reduction curves, scanning electron microscope images...
