Cov hlau nplaum feem ntau tuaj yeem "ko" rau titanium alloys, tab sis feem ntautsuas yog qaug zog heev (lossis tsis yog). Lub tswv yim tseem ceeb yog tias feem ntau titanium alloys yogtsis yog ferromagneticzoo li hlau / hlau, yog li lawv feem ntau tsis teb rau cov hlau nplaum. Qee cov titanium alloys tseem tuaj yeem pomme ntsis attractionnyob ntawm impurities, ua, thiab kuaj tej yam kev mob.
1) Vim li cas titanium alloy hlau nplaum txawv ntawm cov hlau
Cov hlau nplaum nplaum nplaum rau cov khoom uas yogferromagnetic(cov khoom siv lub atoms zoo li ua ke rau hauv cov khoom sib nqus uas tuaj yeem nyob magnetized). Classic piv txwv:
Hlau
Cobalt
Nickel
Feem ntau carbon steels thiab ntau stainless steels
Los ntawm qhov sib txawv,titaniumthiab feem ntau titanium alloys yog feem ntauparamagnetic(tsis muaj zog txaus nyiam) ntau dua li ferromagnetic. Cov ntaub ntawv paramagnetic muaj cov atom uas tsis muaj zog rau cov hlau nplaum, tab sis cov nyhuv feem ntau me me - yog li cov hlau nplaum fridge ib txwm yuav tsis "tuav" lawv.
2) Yam koj yuav tau soj ntsuam hauv kev xyaum
Kev cia siab
Nrog rau feem ntaukev lag luam titanium alloys(piv txwv li, Ti-6Al-4V), ib tug muaj zog handheld hlau nplaum feem ntau qhiatsis pom tseeb lolos yog tsuas yog ib tug heev faint attraction.
Dab tsi yuav ua rau nws zoo li nws sticks ntau dua
Hauv -kev sim ntiaj teb tiag tiag, ob peb yam tuaj yeem tsim kom pom kev nyiam:
Qhov chaw paug(cov hlau me me/steel particles tshuav ntawm ib feem tom qab machining, sib tsoo, los yog tuav).
Residual stresses / microstructure hloovlos ntawm fabrication (feem ntau tsis txaus los tsim cov hlau nplaum muaj zog, tab sis nws tuaj yeem cuam tshuam li cas cov khoom coj).
Alloy impurities(qhov me me ntawm cov khoom sib nqus tuaj yeem ua rau muaj kev nyiam me ntsis).
Coatings los yog cov khoom siv txuas nrog(cov fasteners, inserts, los yog welded qhov chaw ua los ntawm steel).
Yog li yog tias koj cov hlau nplaum "sticks," thawj qhov kev xav hauv kev lag luam feem ntau yogtsis yog titanium alloy nws tus kheej, tab sis lwm yam nyob rau hauv / ib ncig ntawm ib feem.
3) Titanium vs. stainless hlau (kev sib piv muaj txiaj ntsig)
Ntau tus neeg sib piv cov hlau nplaum ntawm "titanium" thiab "stainless steel" thiab tsis meej pem vim:
Qee cov hlau tsis muaj hlau yog hlau nplaum(cov qib ferritic/martensitic).
Ntau cov austenitic stainless hlau tsis yog hlau nplaum lossis tsuas yog tsis muaj zog hlau nplaum.
Titanium alloys feem ntau nyob rau hauv qeb "tsis muaj zog / tsis muaj- hlau nplaum" zoo ib yam li austenitic stainless hlau, tsis yog "muaj zog sib nqus" qeb xws li carbon hlau.
4) Ib txoj hauv kev ntau dua los xav txog nws
Koj tuaj yeem kho cov lus teb magnet li:
Ferromagnetic (muaj zog tuav):hlau / hlau
Paramagnetic (tsis muaj zog heev):feem ntau titanium alloys
Diamagnetic (tsis muaj zog heev repulsion):Qee cov ntaub ntawv xws li tooj liab (tsis yog titanium)
Yog li titanium alloys tuaj yeem pomqeeteb, tab sis feem ntau tsis txaus los tsim kom muaj zog "grab."
5) Yuav ua li cas txheeb xyuas sai sai (kev lag luam- qauv kuaj)
Yog tias koj xav paub tseeb tias nws yog titanium alloy thiab tsis muaj kab mob:
Ntxuav qhov chaw(so, tshem tawm burrs/particles).
Ntsuas ntau lub ntsiab lusthiab sib txawv orientation.
Tshawb xyuas cov khoom txuas uas nyob ze(bolts, brackets, weld hlaws).
Yog muaj, siv azoo magnetometerlos yog paub meej alloy qib / tshav kub ntau los ntawm cov ntaub ntawv.
Hauv qab kab
Feem ntau cov titanium alloys tsis nyiam cov hlau nplaum.
Tej zaum koj yuav pomqaug zog attraction(cov nyhuv paramagnetic), tab sis feem ntau nws yuav tsis coj zoo li hlau.
Yog hais tias nws "sticks" noticeably, nws yog feem ntau vimCov kab mob sib kis los yog txuas cov khoom sib nqus, tsis yog titanium alloy nws tus kheej.
