In this paper,Mo and Al alloying element were introduced into the intergranular region of sintered Nd-Fe-B by intergranular alloying technique to modify the alloy system and microstructure and thus enhance the coercivity of magnets.

Microstructure and Magnetostrictive Properties of Melt-spun Fe-Ga Alloy Ribbons;

A new magnetostrictive material of Fe-Ga alloy developed in recent years is introduced.

The effect of Ga atom on the mean magnetic moment per atom of Fe-Ga alloys was discussed.

Ni-Mn-Ga alloy is well known for its shape memory effect,and now is well-studied in magnetic refrigeration as a potential magnetic refrigerant for its giant magnetocaloric effect.

Using DSC, TEM and compress test, the effect of deformation on martensitic transformation and microstructure of the Ni-Mn-Ga alloy has been investigated.

The effects of exoteric factor including temperature, compressive stress and magnetic field on the martensitic transformation temperature and strain in Ni-Mn-Ga alloys have been studied by means of resistivity measurement, optical microscopy, strain measurement, atomic force microscopy, AC-susceptibility, DSC and X-ray diffraction.
