Precision measurement of dimensional changes in beryllia on neutron diffraction

Neutron diffraction measurement of stress-induced transformation in superelastic NiTi

The formation of stress-induced martensite in superelastic NiTi was studied by neutron diffraction during uniaxial compressive loading and unloading. The respective phase fractions were determined as a function of the applied stresses using a Rietveld refinement with a March–Dollase texture formulation. Before loading, the specimen was fully austenitic. At the highest applied stress of 2625 MPa...

Neutron diffraction analysis on FINEMET alloys

Neutron diffraction has been used to study in situ the nanocrystallization process of Fe73.5Cu1Nb3Si22.52xBx (x55, 9, and 12! amorphous alloys. Nanocrystallization results in a decrease of both the silicon content and the grain size of the Fe~Si! phase with increasing value of x. By comparing the radial distribution function peak areas with those predicted for ideal bcc and DO3 structure, it ca...
