Transformation Reversibility in Fe-Mn-Si Shape Memory Alloy
The change of the surface relief associated with stress-induced epsilon martensite before and after the reverse transformation in an Fe-33%Mn-6%Si alloy (Msz264K) has been investigated. The permanent strain of a 2.7% tensile-strained specimen was 1.1% after the reverse transformation. In this specimen, a large part of surface relief still remained after heating to 623K (above Af). When five tra...
متن کاملTRANSVERSE SPIN FLUCTUATIONS IN 7 - Mn ( 37 % Fe ) ALLOY
The neutron scattering studies of the sublattice magnetization in the vicinity of the N&l temperature in 7 Mno.6Feo.37Cuo.03 alloy reveal its marked critical behaviour. The staggered transverse susceptibility and correlation length remain finite at TN and some anisotropic features of critical scattering are observed. Although the critical magnetic scattering in y-Mn alloys was studied for the f...
متن کاملGrowth and Magnetic Oscillatory Exchange Coupling of Mn/Fe(001) and Fe/Mn/Fe(001)
The magnetic ordering and the interlayer exchange coupling in Mn and Fe/Mn wedge structures grown epitaxially on Fe(001) whisker substrates were investigated using scanning electron microscopy with polarization analysis (SEMPA). In bare Mn/Fe(001) samples, the magnetization of the top Mn layer is collinear with the Fe magnetization, and oscillates between ferromagnetic and antiferromagnetic ali...
متن کاملAnisotropy of Several Properties in a Polycrystalline Fe-Mn-Si Based Shape Memory Alloy
The tensile properties, 7-E transformation and shape recovery have been related to the orientation of tensile axes i.e., along rolling direction(specimen 'A') and toward 45" to the rolling direction(specimen 'B') in a cold-rolled and then annealed Fe-1SMn -10Co-SCr-3Si alloy. It is revealed that the deformation modes of the specimens 'A' and 'B' with respect to tensile axes are not the same; te...
متن کاملSimultaneous enhancement of magnetic and mechanical properties in Ni-Mn-Sn alloy by Fe doping
Both magnetic-field-induced reverse martensitic transformation (MFIRMT) and mechanical properties are crucial for application of Ni-Mn-Sn magnetic shape memory alloys. Here, we demonstrate that substitution of Fe for Ni can simultaneously enhance the MFIRMT and mechanical properties of Ni-Mn-Sn, which are advantageous for its applications. The austenite in Ni44Fe6Mn39Sn11 shows the typical ferr...
