umphandle izixhobo zokwenza izinto ezilukhuni – isenzeko sonyango lobushushu obuphezulu

Ukushisa okuqhelekileyo: ukufudumala kweqondo lokushisa kwesixhobo sokwenza ukuqina komhlaba kuphezulu kakhulu okanye ixesha lokubamba kwiqondo lokushisa eliphezulu lide kakhulu, elibangela ukuba iinkozo ze-austenite zibe lukhuni, okubizwa ngokuba yi-overheating. Kwinkqubo yokucima, i-coarse austenite grains ikhokelela ngokulula ekunciphiseni amandla kunye nokuqina kwentsimbi, okwandisa ubushushu benguqu ye-brittle kwaye kwandisa amathuba okuba nokuguqulwa kunye nokuqhekeka.

Izizathu zokushisa ngokugqithiseleyo: ukungaphumeleli kwesixhobo sokushisa kwesithando somlilo okanye ukuxuba (ngokuqhelekileyo ukungazi kwenkqubo).

Ngaphantsi kweemeko eziqhelekileyo, i-superheated structure i-annealed, i-normalized okanye iphindwe ngokuphindaphindiweyo kwiqondo lokushisa eliphezulu, kwaye i-austenitized ukuze ihlambulule iinkozo.
