Kushandiswa
1. Inonyanya kushandiswa se nodularizer yekugadzira simbi yakakandwa ine ductile.
2. Magnesium iri muNi-Nb inogona kuwedzerwa musimbi yakanyungudutswa zvinobudirira uye zvakachengeteka kuitira kuchengetedza kubuda kwayo uye hunhu hwakakosha hwesimbi yakakandwa.
3. Iyo Nb inogona kunyungudutswa musimbi ye nickel pasina kupatsanurwa, uye kushanda zvishoma nezvishoma kweNb musimbi yakanyungudutswa kunoita kuti ive chinhu chinoshanda zvakanaka, chinodhura uye chakachengeteka muchigadziko. Kana ichienzaniswa nezvimwe zvinhu zvisina Nb, ine kudzoreredzwa kuri nani uye inogona kuona kuti kugadzirwa kwayo kwakagadzikana.
4. Nickel iri muNi-Nb alloys inoshanda segraphitizator uye perlite stabilizer, saka simba rekudhonza uye hunhu hwemakanika hwechinhu ichi zvinogona kuderedzwa. Zvakare nekushandiswa kweNi-Nb, musiyano wechinhu chakareruka uye chinorema chinokandwa unodzikira mukugadzirwa. Uyezve, ine mhedzisiro yakanaka muaustenite nebainite ductile simbi.
