“…8) The increase of the twin boundaries in the M2052 alloy with static strains may result in the increment of the damping capacity. 9) In contrast, the stress-induced movement of the magnetic domain boundaries by magnetostrictive coupling has been considered as the origin of the high damping capacity in ferromagnetic alloys. When preload strains or external magnetic fields are applied, the domain boundaries in the ferromagnetic alloys tend to be constrained and the magnetoelastic damping of the alloys is considerably suppressed.…”

Influences of static strain on the damping capacity in Mn-based M2052 and Fe-6Al alloys were studied with the forced flexural oscillation method by using a dynamic mechanical analyzer (DMA). The static surface strain was applied on the 3-point bending specimens in the range of 1.0 × 10 −5 -2.0 × 10 −4 . The damping capacity of the M2052 alloy showed a continuous increase, but that of the Fe-6Al alloy showed a continuous decrease with increasing static strain in the range below 1.0 × 10 −4 . The variation of the damping capacity with increasing static strain was fitted with an exponential function, and the exponential index turned out to be 0.25 and −0.5 for the M2052 and Fe-6Al alloys, respectively. Static strains in the vicinity of 1.0 × 10 −4 caused the formation of a damping peak, which accelerated the increase of the damping capacity in the M2052 alloy, but softened the decrease of the damping capacity in the Fe-6Al alloy. A significant reduction of the damping capacity appeared at static strains above 1.0 × 10 −4 in both high damping alloys.

“…The loss tangent is a sensitive indicator of cross-linking. The height and area of the tan d peak associated with a transition could be related to the degree of the cure and cross-link density [53,54] . The incorporation of C4 e-BMI increases the tan d value from 0.6 for neat epoxy to 0.5844 and 0.7109 for the 10 wt.% and 15 wt.% C4 e-BMI=epoxy matrices, respectively.…”

The scope of the present work is to toughen the commercial epoxy resin using ether linked bismaleimide (e-BMI) with varying chain lengths C4 and C8. The C4 e-BMI toughened system proves to exhibit synergistic effect on both tensile and impact strengths. Hence the secondary objective of the work is to study the effect of nano alumina on C4 e-BMI toughened epoxy. To overcome the disadvantages generated by the loose nanoparticle agglomerates dispersed in polymer composite, the nanoparticles were functionalized using 3-Glycidoxypropylmethoxysilane (GPS). The nanoindentation behavior of the C4 e-BMI epoxy matrix filled with GPS alumina was studies using Nanoindentation. The strengthening of the matrix interaction by the means of covalent bonding and better dispersion of nanoparticles resulted in enhanced nanohardness and elastic modulus. The addition of GPS Al 2 O 3 nanoparticles to 15 wt.% C4 e-BMI/epoxy matrix increases the nanohardness and elastic modulus up to 5 wt.% of filler loading beyond which the hardness and elastic modulus decrease.

Shape memory alloys offer attractive potentials such as: superelastic behaviour, reversible strains of several percent during heating or cooling over a limited temperature range, generation of high recovery stresses, and a work output with a high power/weight ratio. This paper describes the origin of those properties and gives an overview of the shape memory functions and shape memory applications. Fig. 1. Schematic representation of the volume transformed as a function of temperature.
