“…For that reason, iron aluminides, such as FeAl and Fe 3 Al, have been considered for new hardmetals as alternative binders for cemented carbides. [4][5][6][7][8][9] In this study, densification behavior of TiB 2 -20 mass%-Fe 3 Al and TiB 2 -24 mass%FeAl that were prepared by mixing of mechanically alloyed TiB 2 -Fe powder and Al powder was investigated through pulsed-current sintering. Iron aluminide intermetallic compounds in TiB 2 -Fe-Al were fabricated through self-propagating high-temperature synthesis 10) during sintering.…”

Mechanical alloying and pulsed-current sintering were used to synthesize TiB 2-Fe-Al cermet alloys consisting of titanium boride and iron aluminide intermetallic compound. A mixture was obtained to which Fe was minutely distributed by mechanically alloying TiB 2 powder and Fe powder for 180 ks. Mixture powders of TiB 2-20 mass%Fe 3 Al and of TiB 2-24 mass%FeAl were prepared by mixing an Al powder with this mechanically alloyed powder using a mortar. The added Al reacted with Fe after it had melted when these mixtures were heated. These powders were sintered for a short time and at low temperature using pulsed-current sintering process, but these sintered compacts had pores. Several iron aluminide intermetallic compounds were generated in the TiB 2-20 mass%Fe 3 Al. Therefore, the TiB 2-20 mass%Fe 3 Al compact was hard and brittle. However, the TiB 2-24 mass%FeAl sintered body was composed only of TiB 2 and FeAl, and had better ductility. A slight weight increase resulted from oxidation even though it was heated to 800 K or more in the air, but both sintered compacts retained their pores.

“…The borosilicate glass (Pyrex) which is hard and brittle material and the free-cutting brass (BSBM) which is metallic material are used for work materials. Fe-Al intermetallic compound (FeAl) prospective as a heat-resistant alloy of the next generation is also used for work material [3,4].…”

A gelatin stone having a new polishing mechanism that can polish a free-form surface is proposed in this study. The gelatin based stone can easily control the hardness and the melting point by changing the density, the cooling condition and the kinds of additives. The main conclusions obtained in this study are as follows. The proposed gelatin stone can polish the surface of various materials. The high density of gelatin is suited for a gelatin stone. Surface roughness improves as the polishing time gets longer. Polishing by gelatin stone needs a high-speed relative motion.
