 Apakah MHC aloi tersebut?
Aloi MHC, iaitu karbon aloi molibdenum hafnium, Hf ditambah dan bukannya menggunakan kaedah membentuk dua fasa aloi Ti pengukuhan organisasi molibdenum.
Aloi Prestasi MHC (molibdenum, hafnium aloi karbida) mempunyai hubungan yang baik dengan tahap pemprosesan ubah bentuk, keadaan rawatan haba. Jika sistem MHC, aloi Mo-1Hf-0.05C, dengan spindles diperbuat daripada serbuk metalurgi, menjalin kapasiti ubah bentuk sebanyak 60%, kekuatan tegangan pada suhu 950 ~ 1250 ℃ lebih tinggi daripada TZM 20% arah pemanjangan 10%.
