Tasirin fa'ida na ƙasa da ba kasafai akan kayan ƙarfe mara ƙarfe ba shine mafi bayyane a cikin gami da magnesium.Ba wai kawai ya ƙunshi nau'ikan nau'ikan alluran Mg-RE ba, har ma suna da tasirin gaske akan Mg-Al, Mg-Zn da sauran tsarin gami.Babban aikinsa shine kamar haka:
1. Tace hatsi
Madaidaicin lygs na ƙasa masu ƙarancin ƙarfi na iya tace hatsi na magnesium da magnesium gami.Na farko shine a tace ɓangarorin tsarin simintin.Tsarin tsarin simintin gyare-gyare na abubuwan da ba kasafai ba na duniya don tace sinadarin magnesium ba aikin kwayoyin halitta bane.Hanyar gyaran hatsi mai kyau na magnesium da magnesium gami da sinofs na abubuwan da ba su da yawa na duniya shine haɓakar sanyi a ƙarshen kristal.Na biyu shi ne don hana recrystallization da ci gaban hatsi a cikin aikin sarrafa zafi da kuma aikin annealing.
2. Yin tsarki yana narkewa
Abubuwan da ba a sani ba suna da alaƙa da ƙaiƙayi fiye da magnesium da oxygen, don haka ana iya ajiye su da Rare Earth oxides waɗanda ke amsawa da Mgo da sauran oxides a cikin narkewa sannan cire oxidizing.Yana amsawa tare da hydrogen da tururin ruwa a cikin narkewa, samarwa ko ƙarancin ƙasa oxides waɗanda suka kai niyya na deoxygenation.Tare kuma za su iya ƙara narke ruwa da rage simintin ƙullewa, ci gaba lafiya.
3. Ƙarfin gami da zafin jiki na ci gaba
Yawancin abubuwan da ba kasafai ba a cikin ƙasa a cikin magnesium suna da babban digiri na m solubility, kuma tare da raguwar zafin jiki akwai canji mai mahimmanci a cikin matakin solubility, don haka abubuwan da ba kasafai ba a cikin ƙasa ban da ƙarfafa ƙarfi-mai narkewa, har yanzu yana da amfani mai ƙarfi na ƙarfafa tsufa. na magnesium gami, wasu rare duniya mahadi da dispersive ƙarfafa.
4. Thermal kwanciyar hankali na ci gaba gami da inji ayyuka
Rare ƙasa abubuwa ne mafi amfani alloying abubuwa na ci-gaba magnesium gami zafi juriya, iya muhimmanci inganta high zafin jiki ƙarfi na Mg gami da kuma high zafin jiki creep juriya, da dalilan da suke da yawa: rare duniya stenome coefficient a magnesium ne kananan, iya rage gudu. saukar da recrystallization tsari da ci gaba recrystallization zazzabi, ƙara tsufa sakamako da desoluble lokaci thermal kwanciyar hankali, The rare ƙasa fili tare da high narkewa batu snouts da crystal iyaka, hana da misalignment na motsi, da kuma ci gaba da high zafin jiki creep juriya.
5. Progressive gami lalata juriya
Domin ana tsarkake narkewar, ana rage illolin baƙin ƙarfe na ƙazanta, da dai sauransu, sannan kuma an inganta juriyar lalata.
