Kuzimya no kuvura bivuga uburyo bubiri bwo kuvura ubushyuhe bwo kuzimya hamwe nubushyuhe bwo hejuru, bugamije kwemeza ko igihangano gifite imiterere myiza yubukanishi. Ubushyuhe bwo hejuru bivuga ubushyuhe hagati ya 500-650 ℃. Ibice byinshi byazimye kandi bituje bikora munsi yumutwaro munini ugereranije, kandi bifite ingaruka zimpagarara, kwikuramo, kunama, torsion cyangwa kogosha. Ubuso bumwe nabwo bufite ubushyamirane, busaba kwihanganira kwambara, nibindi. Muri make, ibice bikora munsi yibibazo bitandukanye. Ubu bwoko bwibice nibice bigize imiterere yimashini nuburyo butandukanye, nkibiti, guhuza inkoni, sitidiyo, ibikoresho, nibindi, kandi bikoreshwa cyane mubikorwa byinganda nkibikoresho byimashini, imodoka, na traktori. Cyane cyane kubice binini mugukora imashini ziremereye, kuzimya no kuvura ubushyuhe bikoreshwa cyane. Kubwibyo, kuzimya no kuvura bigira uruhare runini mukuvura ubushyuhe. Mubicuruzwa byubukanishi, ibisabwa kugirango ibintu bizimye kandi bituje ntabwo ari bimwe rwose kubera imiterere yabo itandukanye. Ibice bitandukanye byazimye kandi bifite ubushyuhe bigomba kuba bifite imiterere yubukanishi bwuzuye, aribwo buryo bukwiye bwo guhuza imbaraga nyinshi no gukomera, kugirango ibikorwa byigihe kirekire bikore neza.
Kuzimya nintambwe yambere yuburyo, kandi ubushyuhe bwo gushyuha buterwa nibigize ibyuma, mugihe uburyo bwo kuzimya bwatoranijwe hashingiwe ku gukomera kwicyuma nubunini bwibigize ibyuma. Nyuma yo kuzimya, guhangayikishwa imbere kwicyuma ni muremure kandi koroheje, kandi ubushyuhe burakenewe kugirango ukureho imihangayiko, wongere ubukana, kandi uhindure imbaraga. Ubushuhe ninzira yingenzi muburyo busanzwe bwimikorere yicyuma kizimye kandi gifite ubushyuhe. Umurongo wibikoresho bya mashini yibyuma bitandukanye bihinduka hamwe nubushyuhe bwubushyuhe, bizwi kandi nka tempering curve yicyuma, birashobora gukoreshwa nkibanze kugirango uhitemo ubushyuhe bwubushyuhe. Kubushyuhe bwo hejuru bwubushyuhe bwibyuma bimwe na bimwe byazimye kandi bifite ubushyuhe, hagomba kwitonderwa kwirinda ko habaho ubwoko bwa kabiri bwuburakari bukabije kugirango ibyuma bikoreshwe.

Kuzimya no kuvura bikoreshwa cyane mubice byubaka bisaba imikorere myiza yuzuye, cyane cyane ikorera munsi yimizigo isimburana, nka shitingi yimodoka, ibyuma, moteri ya turbine ya moteri yindege, disiki ya compressor, nibindi. Ibyuma byubaka byubaka bisaba kuzimya ubushyuhe mubisanzwe bizimya no gutwarwa mbere yo kuzimya hejuru kugirango ubone sorbate nziza kandi imwe, ifasha kubutaka bukomeye kandi ishobora no kugera kubintu byiza byubukanishi bwibanze. Ibice bya Nitride bivurwa no kuzimya mbere ya nitriding, bishobora kunoza imikorere yicyuma no gutegura imiterere ya nitriding. Kugirango ugere ku buryo bworoshye bwigikoresho cyo gupima mbere yo kuzimya, kuvanaho imihangayiko iterwa no gukora imashini ikarishye, kugabanya guhindagurika kuzimya, no gukora ubukana nyuma yo kuzimya hejuru kandi imwe, kuvura no kuzimya bishobora gukorwa mbere yo gutunganya neza. Kumashanyarazi yibikoresho hamwe na karbide ya net cyangwa ibinyampeke nyuma yo guhimba, kuzimya no kuvura ubushyuhe birashobora gukoreshwa mugukuraho urusobe rwa karbide no gutunganya ibinyampeke, mugihe spheroid zing karbide kugirango itezimbere imashini kandi itegure microstructure yo kuvura ubushyuhe bwa nyuma.
