Cov tswv yim tshiab txuag hluav taws xob txav tau hu rau kev tsim kho kom zoo dua los ntawm kev txo qis ntawm cov khoom thiab xaiv cov khoom siv tiv thaiv corrosion uas muaj lub zog siab rau qhov sib piv. Kev txo qis ntawm cov khoom siv tuaj yeem ua tau los ntawm kev tsim cov qauv kev ua kom zoo dua qub lossis los ntawm kev hloov cov khoom hnyav nrog cov sib zog ua kom muaj zog. Nyob rau hauv cov ntsiab lus no, forging plays lub luag haujlwm tseem ceeb hauv kev tsim cov khoom lag luam-optimized structural Cheebtsam. Ntawm lub koom haum ntawm Hlau Forming thiab Hlau-Forming Machines (IFUM) ntau yam tshiab forging technologies tau tsim. Hais txog kev ua kom zoo ntawm cov txheej txheem, cov tswv yim sib txawv rau kev txhim kho hauv cheeb tsam ntawm cov khoom raug tshawb xyuas. Hauv zos induced strain hardening los ntawm txoj kev txias forging nyob rau hauv ib tug superimposed hydrostatic siab yuav tsum realised. Tsis tas li ntawd, tswj martensitic zones tuaj yeem tsim los ntawm kev tsim cov theem hloov pauv hauv metastable austenitic steels. Lwm qhov kev tshawb fawb tau tsom mus rau kev hloov ntawm cov hlau hnyav nrog cov hlau tsis muaj zog lossis cov khoom sib xyaw ua ke. Ntau cov txheej txheem forging ntawm magnesium, aluminium thiab titanium alloys rau kev siv aeronautical thiab tsheb sib txawv tau tsim. Tag nrho cov txheej txheem saw los ntawm cov khoom ua cim los ntawm kev simulation-raws li txheej txheem tsim rau kev tsim cov khoom tau raug txiav txim siab. Qhov ua tau ntawm forging complex zoo li tus geometries siv cov alloys tau lees paub. Txawm hais tias muaj teeb meem tshwm sim vim lub suab nrov ntawm lub tshuab thiab qhov kub thiab txias, cov txheej txheem acoustic emission (AE) tau ua tiav rau kev soj ntsuam online ntawm forging tsis xws luag. Tshiab AE tsom xam algorithm tau tsim, kom cov qauv teeb liab sib txawv vim muaj ntau yam xwm txheej xws li khoom / tuag tawg lossis tuag hnav tuaj yeem kuaj pom thiab cais. Tsis tas li ntawd, qhov ua tau ntawm kev hais txog kev siv thev naus laus zis tau ua pov thawj los ntawm kev txheeb xyuas qhov kawg (FEA). Piv txwv li, kev ncaj ncees ntawm forging tuag nrog rau kev sib tsoo pib vim yog thermo-mechanical qaug zog nrog rau kev puas tsuaj ntawm forgings tau tshawb xyuas nrog kev pab los ntawm cov qauv kev puas tsuaj. Nyob rau hauv daim ntawv no, ib co ntawm cov uas hais txog mus kom ze tau piav.
