Ingxubevange ngokuvamile ibhekwa njengesixazululo esiqinile esiyingxenye noma esiphelele se-elementi eyodwa noma ngaphezulu ku-matrix yensimbi. Ama-alloys esixazululo esiqinile aphelele anikeza isigaba esiqinile se-microstructure, kuyilapho izixazululo eziyingxenye zinikeza izigaba ezimbili noma ngaphezulu ezingase zibe nokusabalalisa okufanayo kuye ngomlando wokwelashwa okushisa noma ukushisa. Ama-alloys ngokuvamile anezakhiwo ezihlukile kunezakhi zawo zengxenye. Ukuhlanganisa insimbi eyodwa nezinye izinsimbi noma okungezona insimbi kuvame ukuthuthukisa izici zayo. Ngokwesibonelo, insimbi inamandla kunensimbi, kuyilapho insimbi iyisici sayo esiyinhloko. Izakhiwo zomzimba, njengokuminyana, ukusebenza kabusha, i-Young's modulus, i-electrical and thermal conductivity ye-alloy ingase ingahlukani kakhulu naleyo yezakhi zayo, kodwa izakhiwo zobunjiniyela, njengokuqineka namandla okugunda zingase zehluke kakhulu kulezo zezinto ezihlanganisayo. Lokhu ngezinye izikhathi kungase kube ngenxa yobukhulu obuhlukene bama-athomu kungxubevange, ngoba ama-athomu amakhulu asebenzisa amandla acindezelayo kuma-athomu angomakhelwane, futhi ama-athomu amancane asebenzisa amandla aqinile komakhelwane bawo, esiza ingxubevange ukumelana nokuguquguquka. Ngezinye izikhathi ama-alloys angase abonise umehluko ophawulekayo ekuziphatheni ngisho nalapho amanani amancane e-elementi eyodwa ethulwa. Njengesibonelo, ukungcola kuma-alloys e-ferromagnetic ahambisa kancane kubangela izakhiwo ezihlukene. Amanye ama-alloys enziwa ngokuncibilika nokuxuba izinsimbi ezimbili noma ngaphezulu. I-Brass iyingxube eyenziwe ngethusi ne-zinc. Ithusi, elisetshenziselwa amabhere, izithombe, imihlobiso nezinsimbi zesonto, liyingxube yethusi nethini. Ngokuphambene nezinsimbi ezihlanzekile, ama-alloys ngokuvamile awanayo indawo yokuncibilika eyodwa. Esikhundleni salokho, banobubanzi bokuncibilika lapho okubalulekile kuyingxube yezigaba eziqinile neziwuketshezi. Izinga lokushisa lapho ukuncibilika kuqala khona kubizwa ngokuthi i-solidus kanti izinga lokushisa lapho ukuncibilika sekuphelile libizwa ngokuthi i-liquidus. Kodwa-ke, kuma-alloys amaningi kunengxenye ethile yezakhi (ezimweni ezingavamile ezimbili) enephuzu elilodwa lokuncibilika. Lokhu kubizwa ngokuthi ingxube ye-alloy eutectic.

 

I-AGS-Engineering inolwazi lwezinsimbi nama-alloys kulezi zihloko ezilandelayo:

• I-Metallurgy, ukucutshungulwa kwensimbi, ama-alloys, ukuphonsa, ukubumba, ukubumba, ukukhishwa, ukuguquguquka, ukukhanda, ukudweba izintambo, ukugoqa, i-plasma kanye nokucubungula nge-laser, ukwelashwa kokushisa, ukuqina (ukuqina kwezulu nemvula) nokuningi.

Amaqhinga afana nokuhlolwa kwemishini (i-elasticity, amandla aqinile, amandla e-torsion, ukuhlolwa kwe-shear, ubulukhuni, ukuqina okuncane, umkhawulo wokukhathala... njll.), ukuhlolwa komzimba, i-X-ray diffraction (XRD), i-SEM & TEM, i-metallurgical microscopy, ukuhlolwa kwamakhemikhali amanzi kanye amanye amasu ezinto ezibonakalayo. Ukuhlola okulimazayo nokungonakali. Uphenyo lwezakhiwo zomzimba, zemishini, ze-optical, ezishisayo, zikagesi, zamakhemikhali nezinye. Ukuthuthukiswa kokuhlolwa kwangokwezifiso kwezingxenye zesakhiwo, izibophelelo nokunye okunjalo.

• Uphenyo lokuhluleka kwensimbi, ukufunda ngokugqwala, i-oxidation, ukukhathala, ukungqubuzana nokuguga.

• Ukuhlonzwa Kwempahla Enhle, ukuqinisekiswa kanye nokuhlonzwa kwesisekelo sempahla yemikhumbi, amabhayela, amapayipi, amakhreni asebenzisa amasu afana nesandla esiphathwayo esingabhubhisi esibanjwe i-X-ray Fluoresce  Machine (XRF), XRF at alloy nganoma yisiphi isikhathi. Insimbi ye-XRF ingahlinzeka ngokuhlaziywa kwekhwalithi nobuningi, ingakwazi ukuhlonza izakhi, ilinganise ukugxiliswa kwento ngayinye futhi izibonise kuyunithi. Indlela yesibili esiyisebenzisayo i-Optical Emission Spectrometry (OES). Inzuzo eyinhloko ye-Optical Emission Spectrometry ukugxilisa okuguquguqukayo komugqa kokuhlaziya kusukela ezingxenyeni zamaleveli ebhiliyoni (ppb) kuya ezingxenyeni zamaleveli ayisigidi (ppm) kanye nekhono lokuhlaziya izici eziningi ngesikhathi esisodwa.

Sisebenzisa ukuhlaziywa kwezibalo kanye nokulingisa kwekhompuyutha ukuze sibikezele imiphumela futhi sinikeze isiqondiso kumakhasimende ethu. Senza nokuhlola ngelebhu noma nini lapho kudingeka. Ukuqhathanisa ukuhlaziya nezivivinyo zomhlaba wangempela kwakha ukuzethemba. Sisebenzisa amasu athuthukile ezibalo kanye nokulingisa, sibikezela i-kinematics (imodeli yokunyakaza), amaphrofayili aphoqelela (i-static kanye ne-dynamic), ukuhlaziywa kwesakhiwo, ukuhlaziya ukubekezelelana, i-FEA (i-dynamic, i-non-linear, i-thermal eyisisekelo) nokunye. Nazi ezinye izindlela nesofthiwe namathuluzi okulingisa esiwasebenzisayo ekusebenzeni ngezinsimbi nama-alloys ensimbi:

• Umsebenzi wokuthuthukisa i-2D ne-3D usebenzisa amathuluzi afana ne-AutoCad, i-Autodesk Inventor ne-Solidworks

• Amathuluzi asekelwe ku-Finite Element Analysis (FEA).

• Ukuhlaziya okushisayo nokulingisa kusetshenziswa amathuluzi afana ne-FloTHERM, i-FloEFD, i-FloMASTER, i-MicReD, i-Coolit, i-SolidWorks, i-CADRA, amathuluzi omklamo wangaphakathi.

• Izibalo zesipredishithi ezenziwe ngezifiso ze-MathCAD / ze-excel zokuhlaziywa kwesakhiwo nokuklama

• Amanye amathuluzi athile esihlokweni okusakaza kwensimbi, i-extrusion, forging….njll., njenge-FLOW-3D Cast, MAGMA 5, Click2Extrude, AutoForm-StampingAdviser, FORGE…..etc.

Minyaka yonke senza futhi sithumele iziqukathi eziningi zensimbi nezingxenye ezihlanganisiwe zensimbi, izingxenye ezivela emithonjeni yethu eseNingizimu-mpumalanga ye-Asia kuya kumakhasimende ethu emhlabeni wonke, ikakhulukazi emazweni ase-US nase-EU.  Ngakho-ke izinsimbi nama-alloys ensimbi yindawo esinesipiliyoni kuyo isikhathi eside. Uma unentshisekelo enkulu emandleni ethu okukhiqiza esikhundleni sobunjiniyela, sincoma ukuthi uvakashele indawo yethu yokukhiqiza ngokwezifiso.http://www.agstech.net
