摘要： A method of brazing a Ti-15 Mo-3 Nb-3 Al-0.2 Si base material includes the steps of coating a braze material onto a base material. The braze material comprises substantially only a Ti--Cu--Ni--Zr mixture, with the mixture comprising about 40 wt % Ti. In particular, the braze material may comprise 40Ti-20 Cu-20 Ni-20 Zr. A following step includes heating the braze material and then forming a braze joint between the braze and base materials. The heating step can occur from about 760 to 932.degree. C. and over 15 to 90 minutes.

摘要： Selected scene regions are imaged. IMAGING CHANNEL: mirrors (preferably MEMS) address an imaging sensor to regions. CALIBRATION CHANNEL: the mirrors direct radiation from a source to a calibration sensor, along an imaging-channel segment. Beam splitter(s) let the channels share optical path at the mirrors. To minimize imaging-channel diffractive blur, the calibration channel modifies wavefront angle and smoothness at the mirrors—measuring (and setting mirrors to optimize) PSF sharpness, then applying these measurements (and settings) to optimize imaging-channel settings by iterative multidimensional gradient search. An afocal lens receives scene radiation, magnifying deflection at the scene. An FOR is imaged on the imaging sensor; the mirrors address the sensor to a narrow FOV within the FOR; the lens enlarges deflections to cover the FOR. Plural diffraction-grating orders communicate between calibration source and sensor when the selected region is in plural scene portions, regardless which FOV is addressed.

摘要： A braze material and method of brazing titanium metals. The material may consist of Ti, Ni, Cu Zr, PM and M where PM is a precious metal and M may be Fe, V, Cr, Co, Mo, Nb, Mn, Si, Sn, Al, B, Gd, Ge or combinations thereof, with the (Cu+PM)/Ni ratio around 0.9. Optionally, a second brazing may be performed to rebraze any braze joint that did not braze successfully. The second brazing material has a lower braze temperature than the first and may consist of a mixture of Ti, Ni, Cu, Zr PM and M with from 1-20 wt % more Zr, PM, M or combinations thereof than the first braze. The braze material may be placed on a base material, in a vacuum furnace, and heated to form a braze joint between the braze and base material. The heating step may occur from about 800-975° C. and over 3 to 15 minutes.
