Kev sib xyaw thiab kev faib tawm ntawm Metallurgical Microscopes
Metallurgical microscopes yog cov cuab yeej siv thev naus laus zis tsim los ntawm kev sib koom ua ke kho qhov muag microscopy, photoelectric hloov dua siab tshiab thiab lub computer duab ua thev naus laus zis. Metallographic dluab tuaj yeem yooj yim saib ntawm lub computer rau kev tsom xam metallograph, muab qhab nia, nrog rau cov duab xa tawm thiab luam ntawv. Lawv tau muab faib ua upright metallurgical microscopes (GPM-100, IDL-100), inverted metallurgical microscopes (MG-MI, GX51, GX41), portable field metallurgical microscopes (MG-100), thiab hais txog. Raws li paub zoo, alloy muaj pes tsawg leeg, cov txheej txheem kev kho cua sov thiab cov txheej txheem ua haujlwm txias / kub ncaj qha hloov cov txheej txheem sab hauv ntawm cov khoom siv hlau, uas hloov pauv cov khoom siv ntawm cov khoom. Yog li ntawd, kev soj ntsuam, tshuaj xyuas thiab tshuaj xyuas lub microstructure sab hauv ntawm cov hlau nrog lub tshuab ntsuas metallurgical yog ib txoj hauv kev tseem ceeb hauv kev tsim khoom.
Lub tshuab ntsuas hlau metallurgical feem ntau muaj cov khoom siv kho qhov muag, lub teeb pom kev zoo, lub tshuab hluav taws xob thiab cov khoom siv (nrog rau cov khoom siv yees duab lossis cov cuab yeej ntsuas microhardness, thiab lwm yam). Raws li cov yam ntxwv ntawm lub teeb pom kev sib txawv ntawm cov microconstituents nyob rau saum npoo ntawm cov qauv hlau, lub tshuab tsom iav ua cov kev tshawb fawb kho qhov muag ntawm cov khoom siv hauv qhov pom lub teeb pom kev zoo rau qhov zoo thiab ntau yam ntxwv. Nws tuaj yeem nthuav tawm cov yam ntxwv ntawm cov hlau microstructural ntawm cov nplai ntawm 500 μm mus rau 0.2 μm.
Thaum ntxov li xyoo 1841, tus kws tshawb fawb Lavxias PP Anosov tau kawm txog cov qauv ntawm Damascus steel ntaj hniav hauv qab lub iav loj. Nyob rau hauv 1863, lub
Tus kws tshawb fawb Askiv HC Sorby tau qhia txog cov txheej txheem petrological, suav nrog kev npaj cov qauv, polishing thiab etching, rau hauv kev kawm ntawm hlau thiab hlau thiab tsim metallography. Nws kuj coj ib tug series ntawm low-magnification metallographs ntawm microstructures. Kev tshawb fawb ua haujlwm ntawm Sorby, ua ke nrog nws cov neeg kawm A. Martens (Lub Tebchaws Yelemees) thiab F. Osmond (Fabkis), tau tsim lub hauv paus rau niaj hnub optical metallography. Los ntawm lub xyoo pua 20th, optical metallography tau loj hlob tuaj thiab tau siv dav rau microanalysis ntawm cov hlau thiab alloys, thiab nws tseem yog cov txheej txheem tseem ceeb hauv kev lag luam metallurgy rau niaj hnub no.
