In this paper, submicron-porous NiTi and NiTiNb shape memory alloys were firstly fabricated by a new top-down process, including solidified phase controlling and etching process.
The system makes use of low temperatures at night to solidify the phase change material, and store it solid for a later cooling supply to the interior of the building.
In sRE123 specimens, the metastable high-temperature phase, the RE4Ba3O9 (RE430) phase, solidified primarily from undercooled melt, while the nRE123 phase solidified primarily in nRE123 specimens.
Then the polymer-rich phase solidifies quickly, whereas the solvent-rich phase delays the solidification.
The results show that particularly fine and homogeneous microstructures without strong segregation can be obtained for certain alloy compositions solidifying through the β phase.
A special advantage of MA is to produce alloys of immiscible elements such as Cr-Cu[4], Ag-Cu, Cu-Fe[5], Cu-W[6, 7], and Al-Pb[8], which are difficult to produce by conventional methods because of the problem of heavy segregation while solidifying from the liquid phase.
The degree of elements segregation in liquid films determines whether liquid films solidify into eutectic phases or cause hot cracks.
Cu, Pb and Cd were mainly solidified within interstitial phases of the clinkers forming solid solutions with the variable compositions.
54, 55 The value of anti-VEGF therapy in the treatment of DME emerged from the Phase II ranibizumab trials (RESOLVE and READ-2) 56– 59 and was solidified in several Phase III trials (RESTORE, DRCR.net Protocol I, and RISE/RIDE).
Intermetallic TiAl alloys solidifying via the disordered β phase, such as the TNM alloy, are promising γ-TiAl based materials as balanced mechanical properties are attained by conventional manufacturing routes and subsequent heat-treatments.
