Cast and annealed at

Kan] As-cast and annealed at 700°C alloys were studied by optical microscopy, XRD and DTA. The liquidus surface projection and isothermal section at 700°C were presented for the field Cr-Cr2B-Fc2B-Fe.

THF (5 g) mixed with 0.1 ml 10 NHC1 and added slowly to 5 g of titanium isopropoxide with fast stirring. This sol was then mixed with a 10 wt% solution of triethoxysilane capped PF or PEK in THF. The final solution was cast into poly(4-methyl-pentene) Petri dishes and covered for drying and curing at 60 °C for 24 h. Films were then removed and annealed at 200 °C for 15 min... 

Figure 1. Representative metallography of Ti/Mo samples before and after annealing, etched and magnified X125. Ti Mo is presented after meltingy crushing, and remelting six times. TiMo is presented after similar casting, then annealing at 1200°C for 48 hr.

Light Microscopy. Although films of the terpolymer were birefrin-gent, no spherulites could be detected regardless of the manner in which specimens were prepared. Samples cast from a 2% solution in tetra-hydrofuran (THF) and annealed at 60 °C overnight had optical melting points which ranged from 63° to 75°C. 

Cobalt is magnetic at all temperatures up to about 1150° C., at which point it becomes non-magnetic.1 When placed in a magnetic field a bar of cobalt increases in length,2 and it is interesting to note in this connection that this magnetic elongation for both cast and annealed cobalt becomes practically nil between 1100° and 1200° C.3... 

Figure 14. WAXD of a SGLC-coil with semifluori-nated groups SIH5F8-4I/64. The sample was simply cast from dilute solution with trifluoromethyl-ben-zene over a period of one week coupled with drying for 2 days at room temperature and annealing at 140 °C for 4 days in a vacuum oven (a) at 30 °C SmB phase (b) at 60 °C, SmA phase (c) at 80°C, isotropic phase (d) cooled to 30 °C from isotopic phase.

For the as-cast and annealed samples, the CaPbs phase was observed at the grain boundaries. The amount of this phase increased with increasing Ca content in alloy. In the annealed alloy, the Ag-rich phase was observed as round granules at the grain boundary, and the silver concentration of the Ag-rich phase increased for any increase in the annealing time. 

Ternary alloys in the vicinity of Y disilicides revealed different phase equilibria depending on the heat treatment the phase distribution as derived from alloys in as-cast condition is shown in fig. 49b. The solubility of Al in YSij 55 (AlB2-defect type) in both cases of as-cast and annealed alloys was claimed to proceed along an unusual path similar to the solution of Ni in YSij 55 (see Y-Ni-Si) the maximum solubility of Al at 500°C was shown to be at 15 a/o Al (Muravyova et al., 1971). 

The Rodent for testing was obtained by melting of the original alloys. At first a protot5q)e was made of wax then the mold was prepared. Casting and annealing of the mold was performed in a vacuum/pressure furnace. 

Test specimens for tensile property measurements (Instron tester) were prepared by either casting from dilute solution or molding at 150 C, 12,000 psi for 5 minutes in an hydraulic press and annealing at a rate of l C/minute. The cast film samples were stored in a vacuum oven at 60°C for 3 days prior to testing,... 

Ultimate tensile and tensile yield strength vs temperature with varying crosshead speed for p preform material. Specimens were 160 mm (6.3 in.) diameter bar processed from 818 kg (1800 lb) cast and extruded ingots, and annealed at 925 °C (1700 °F), 1 h, AC.
