Melt processing of (Sm-123) is done by infiltrating liquid phases into an Sm-211 preform and allowing the growth of Sm-123 to take place. The melt-textured samples are found to be free of macrodefects, and the microstructure contains uniformly distributed fine-sized Sm-211 particles. The behaviour of the critical current density of the samples in high fields is reported here.

Composites made of light materials are of great interest and this material replaces almost all the monolithic materials while posing challenges for machining. While machining these composites, the failure of cutting tool is attributed for the presence of hard particles in the work materials. Further, cryogenic treated cutting tools are recognized for machining of monolithic materials. Thus, present paper presents the results on tool life of cryogenically treated and untreated K10 grade carbide inserts while machining Al6061-fly ash composites containing 0-15 percent reinforcement in steps of 5. Intermittent facing operation were carried out with the cutting speed of 220m/min, 314m/min & 446m/min, by using the feed rate of 0.06mm/revolution, 0.12mm/revolution, 0.24mm/revolution with a depth of cut of 2mm following dry machining method. Parametric studies have been carried out as per ISO3685 standards. The results reveal that cryogenically treated tungsten carbide inserts exhibits higher toughness & improved wear resistance when compared to untreated tungsten carbide inserts.
