The Effect of Desflurane on Myocardial Contractility and Coronary Flow in Isolated Rat Hearts

Damping Capacity of Co-Mn System

“…7, indicating that no magneto-mechanical damping contributes to the damping capacity of Co-(21-26%)Mn alloys. Therefore, the damping capacities of Co-Mn alloys except for the " free Co-26%Mn alloy are probably due to the movement of defects associated with " martensite itself, such as the movement of =" interfaces and the movement of stacking fault boundaries in " plate, as reported in the previous studies [7][8][9][10] about Fe-Mn alloys. In the case of Co-26%Mn alloy, the movement of stacking fault boundaries existing in the phase is considered to contribute to the damping capacity of the alloy because of no existence of " martensite.…”

“…Recently, we have reported [7][8][9][10] that an Fe-17%Mn alloy undergoing (fcc) ! "(hcp) non-thermoelastic martensitic transformation possesses a high damping capacity which is strongly dependent on the amount of " martensite.…”

Mechanical Properties of Fe–Mn–Si Based SMA and the Application

“…The particular attention will be paid for the shape recovery strength and the large damping effect governed by motion of the Shockley partial dislocations. Concerning the latter property, Fe-Mn and Fe-Mn-Cr alloys [21][22][23][24] are reported to show a high damping effect due to existence of " (" 0 ) phase. The shear deformation governed by motion of the Shockley partial dislocations plays an important role in the highmanganese (15-25 mass%) steels.…”

Effect of Deformation on Damping Capacity and Microstructure of Fe–22%Mn–8%Co Alloy

“…In previous studies, [1][2][3][4] some of the authors have reported that Fe-Mn alloy undergoing (fcc) ! "(hcp) martensitic transformation possesses a high damping capacity, which is strongly dependent on the amount of " martensite.…”

“…martensitic alloys are attributed to the movement of the stacking fault boundary in " martensite, " martensite variant boundary and =" interface, in single or multiple. [1][2][3][4] In the present study, cobalt (8% in mass) which is known to reduce the stacking fault energy of the austenite phase in Fe-based alloys, 10) was added to Fe-22%Mn, and the coldrolling was carried out on the alloy at room temperature to increase the volume fraction of " martensite by the stressinduced martensitic transformation. Then the damping capacity and microstructure of the alloy were investigated as a function of deformation degree.…”
