Abstract:

 

Invar  alloys  have  great  importance due  to  their  low thermal expansion coefficient.    The  effect of Al doping on Fe65 Ni35   Invar  alloy was investigated by temperature-dependent   magnetization and  elastic  modulus  measurements. First, 0.44 at%  and  2.24 at%  of Al were   substituted for Ni.  Then  X-ray  diffraction measurements, Rietveld refinements, and  scanning    electron  microscopy  studies  were  performed to  understand the  effect  of Al-doping  on  the    face-centered cubic  structure.  The  elastic  modulus  of Fe65 Ni35    and  the  Al-doped    samples  were measured in the  temperature range  300 ≤ T  ≤ 870 K using impulse  excitation. The  temperature dependence of magnetization and    elastic  modulus  results  for the  Al-doped  Invar  alloys were compared with  those  of nondoped Invar  alloy.  Al doping    to Fe65 Ni35   Invar  alloy led to volume  shrinkage and  decreasing  Curie  temperature as seen   in the  effect of hydrostatic pressure  application.
