Background: The migrant intervention in India was initiated during the National AIDS Control Program (NACP) Phase-2 (2002-2007). Even by the end of NACP Phase-3 (2010-11); the service uptake among migrants remained very low (14% referred for HIV test

The technique of Self-propagating High-temperature Synthesis (SHS) was used to prepare NiAl from compacts using elemental powder mixtures in stoichiometric amounts under vacuum and argon atmosphere. Considerable changes in the oxygen contents of the

The complete identity of a second-phase precipitate detected by transmission electron microscopy in combustion-synthesized NiAl was established. The crystal structure, including the point group, the space group and the lattice parameters, was determi

The martensitic microstructures of Ni Ti shape memory alloys were examined by transmission electron microscopy and found to be self accommodating conglomerates of large primary (or first formed) plates and smaller secondary martensite plate clusters.

Neutron diffraction measurements, performed in presence of an external magnetic field, have been used to show structural evidence for the kinetic arrest of the first-order phase transition from (i) the high temperature austenite phase to the low temp

Because of their austenitic-ferritic microstructures, duplex stainless steels offer a good combination of mechanical and corrosion resistance properties. However, heat treatments can lower the mechanical strength of these stainless steels as well as

The course of the martensitic transformation is affected by strain fields in the untransformed parent phase, One of the consequences of this NiTi shape memory alloys is the “Thermal Arrest Memory Effect” (TAME), where the martensite to parent

The ordering transformation in the Cu 69 Zn 14 Al 17 shape-memory alloy has been studied with Doppler-broadened annihilation-radiation line-shape-parameter (S) and lifetime measurements. The S-parameter profile as a function of temperature, S(T), fro

The significant property of shape memory alloys (SMA) is the ability to recover after deformation and upon unloading or heating, the predeformation microstructure or the microscopic shape. This property is essentially due to the self-accommodating na
