An Investigation of the Use of Ni3Al Intermetallic Compound for Fabrication of Al Matrix Composites

Fabrication and characterization of aluminum matrix composites containing different volume fractions of Ni3Al powder (5-40 Vol%) were investigated. Ni3Al powder was produced by mechanical alloying of elemental nickel and aluminum powder mixture. Al-Ni3Al composite parts were prepared using a powder metallurgy route involving two stages Al and Ni3Al powder mixtures were first compacted under 500...

Microstructural Characterization of Carburized Steels

*Member of ASM International arburizing has been a popular method for obtaining a unique balance of properties in steels for many years. Steels with low carbon contents are characterized by good toughness and good ductility, but low strength and low wear resistance. By locally increasing the carbon content at the surface, followed by heat treatment to produce a very high hardness in this layer ...

Confirming the Composition of Shape Memory Alloys by Microstructural Characterization

It is well known that the properties of shape memory alloys, such as binary Ni-Ti (nitinol), are very sensitive to composition.[1-3] Especially on the Ni-rich side of stoichiometry, the martensite/austenite phase transformation temperature decreases abruptly when Ni is increased only a few tenths of a weight percent.[4] In ternary high temperature shape memory alloys (HTSMAs) containing Pt, Pd,...
