Ti6Al4V daim ntawv titanium

Ti6Al4V daim ntawv titanium phaj

Kub dov, annealed, descaled, thiab flattened, muaj ib tug deg tsos piv rau kev lag luam corrosion-

resistant steel No. 1 tag. Cov khoom lag luam phaj yuav tsum tau tsim los siv cov txheej txheem kev lag luam rau kev tsim cov phaj rau cov khoom tuab. Bar, billet, forgings, los yog forging Tshuag yuav tsis raug hloov rau lub phaj.

3.4 Kev sib tw

Cov khoom yuav tsum tau muab tshem tawm los ntawm cua sov mus rau qhov kub ntawm qhov ntau ntawm 1 300 mus rau 1 650 degree F (704 txog 899 degree), tuav ntawm qhov kub xaiv nyob rau hauv ± 25 degree F (±{5}} degree) rau ib lub sij hawm sib haum nrog cov khoom tuab thiab cov khoom siv cua sov thiab cov txheej txheem siv, thiab cua txias ntawm tus nqi uas yuav tsim cov khoom raws li qhov yuav tsum tau ua ntawm 3.5. Pyrometry yuav tsum ua raws li AMS2750.

3.5 Khoom

Cov khoom yuav tsum ua raws li cov cai hauv qab no thiab tseem yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm 3.5.1 thiab 3.5.2 tom qab rov ua cua sov rau 1325 degree F ± 1 5 (718 degree ± 8), tuav ntawm qhov kub li 20 feeb ± 2, txias ntawm tus nqi sib npaug rau cua txias lossis qeeb dua.

3.5.1 Tensile Properties

Yuav tsum ua raws li tau teev tseg hauv Table 2, txiav txim siab raws li ASTM E8 / E8M nrog tus nqi ntawm strain teem ntawm

{{0}} 005 nti/inch/feeb (0.005 mm/mm/minute) thiab tswj nyob rau hauv ib tug kam rau ua ntawm ± 0.002 nti/inch/feeb

({0}}.002 mm/mm/minute) los ntawm 0.2% offset yield strain.

3.5.2 Khoov

Ti6Al4V daim ntawv titanium phajnyob rau hauv {{0}}.1875 nti (4.762 mm) nyob rau hauv nominal thickness yuav tsum muaj ib tug xeem qauv npaj nominally {{10}}.750 nti (19.06 mm) nyob rau hauv dav, nrog nws axis ntawm bending parallel mus rau kev taw qhia ntawm dov. Cov qauv yuav tsum tau khoov mus kuaj ua raws li cov kev taw qhia khoov qhov ntsuas tau teev tseg hauv ASTM E290 los ntawm lub kaum sab xis ntawm 105 degrees. Cov kev txhawb nqa kev sim yuav tsum muaj lub vojvoog sib cuag 0.010 nti (0.25 hli) yam tsawg kawg nkaus, thiab lub plunger yuav tsum muaj lub vojvoog sib npaug ntawm qhov khoov qhov ntsuas tau qhia hauv Table 3 zaug ntawm nominal thickness. Kev kuaj xyuas ntawm tus qauv khoov yuav tsis pom cov pov thawj ntawm kev tawg thaum kuaj ntawm 1 5 txog 25X magnification.
