Influence of Deep Cryogenic Treatment on Microstructure and Properties of 7A99 Ultra-High Strength Aluminum Alloy

INFLUENCE OF NANO SILICA ON PROPERTIES AND MICROSTRUCTURE OF HIGH ALUMINA ULTRA-LOW CEMENT REFRACTORY CASTABLES

Colloidal silica bonded refractory castables have been developed recently. It was found that colloidal silica is one of the best binders can substitute other binders such as cement in No Cement Castable (NCC) and Ultra Low Cement Castable (ULCC) refractories. Also composition of colloidal silica with appropriate additives resulted in a gel form which makes the initial strength. Moreover, the na...

The effect of deep cryogenic treatment on mechanical properties of 80CrMo12 5 tool steel

Cryogenic treatment can be used as a supplemental treatment that is performed on some tool steels between quenching and tempering as an effective method for decreasing retained austenite and increasing wear resistance. In this research, the effect of deep cryogenic treatment (DCT) on dimensional stability and mechanical properties of 80CrMo12 5 tool steel was investigated. The martensitic trans...

effects of solution treatment on the microstructure and wear behavior of 332 aluminum alloy

the effect of t6 heat treatment on the microstructure and wear behavior of al-332 piston alloy containing 1.2wt% iron was investigated. the results showed that the t6 heat treatment changed the morphology of acicular eutectic si particles to a more spherical form. the heat treatment also reduced the average length and blunted the needle-like ?- phase intermetallics through dissolution and fragm...
