Mmepe na mmepụta nke ihe na-abụghị magnetik siri ike alloy bụ ngosipụta pụtara ìhè nke ihe ọhụrụ siri ike alloy. A na-eme alloy siri ike site na ijikọ carbide metal refractory nke IV A, VA, na VI A na tebụl oge nke ihe (dịka tungsten carbide WC), yana ngbanwe metal nke otu iron (cobalt Co, nickel Ni, Iron Fe) dị ka usoro njikọ site na ụlọ ọrụ metallurgy ntụ ntụ. Carbide tungsten dị n'elu abụghị magnetik, ebe Fe, Co, na Ni niile bụ magnetik. Iji Ni dị ka ihe nkedo bụ ọnọdụ dị mkpa maka imepụta alloys na-abụghị magnetik.
Enwere ụzọ ndị a maka ịnweta usoro WC Ni na-abụghị magnetik hard alloys:1. Jikwaa ọdịnaya carbon nke ọma
Dị ka WC Co alloy, carbon ọdịnaya bụ isi ihe na-emetụta ike ngwọta siri ike nke W na njikọ nke WC Ni alloy. Nke ahụ bụ, na-ebelata ọdịnaya carbon nke carbon compound na alloy, na-abawanye ikike ngwọta siri ike nke W n'oge njikọ njikọ Ni, yana mgbanwe dị iche iche nke ihe dịka 10-31%. Mgbe ngwọta siri ike nke W na usoro Ni bonded karịrị 17%, alloy na-aghọ demagnetized. Ihe kachasị mkpa nke usoro a bụ ịnweta alloys siri ike na-abụghị magnetik site na ibelata ọdịnaya carbon yana ịba ụba ngwọta siri ike nke W na usoro njikọ. Na omume, a na-ejikarị ntụ ntụ WC nke nwere carbon dị ala karịa ọdịnaya carbon carbon, ma ọ bụ W ntụ ntụ na-agbakwunye na ngwakọta iji nweta ebumnuche nke imepụta alloys dị ala. Agbanyeghị, ọ na-esiri ike imepụta alloys na-abụghị magnetik naanị site na ịchịkwa ọdịnaya carbon.
2. Tinye chromium Cr, molybdenum Mo, tantalum Ta
Igwe ọkụ dị elu WC-10% Ni (wt% n'ịdị arọ) alloy na-egosipụta feromagnetism na okpomọkụ ụlọ. Ọ bụrụ na agbakwunyere ihe karịrị 0.5% Cr, Mo, na 1% Ta n'ụdị ọla, nnukwu carbon alloy nwere ike ịgbanwe site na feromagnetism gaa na-abụghị magnetism. Site n'ịgbakwụnye Cr, ihe ndọta nke alloy na-adabere na ọdịnaya carbon, na Cr bụ n'ihi nnukwu ego nke ngwọta siri ike na njikọ njikọ nke alloy, dị ka W. Alloy na Mo na Ta nwere ike gbanwee naanị n'ime a. alloy na-abụghị magnetik na ụfọdụ ọdịnaya carbon. N'ihi obere ngwọta siri ike nke Mo na Ta na usoro njikọ, ọtụtụ n'ime ha na-ejide carbon na WC iji mepụta carbide kwekọrọ ekwekọ ma ọ bụ carbide siri ike ngwọta. N'ihi ya, ihe ngwakọta alloy na-atụgharị gaa n'akụkụ akụkụ carbon dị ala, na-ebute mmụba na ngwọta siri ike nke W na usoro njikọ. Usoro ịgbakwunye Mo na Ta bụ ịnweta alloy na-abụghị magnetik site na ibelata ọdịnaya carbon. Ọ bụ ezie na ọ dịghị mfe ijikwa dị ka ịgbakwụnye Cr, ọ dị mfe ịchịkwa ọdịnaya carbon karịa WC-10% Ni alloy dị ọcha. A gbasaala oke ọdịnaya carbon site na 5.8-5.95% ruo 5.8-6.05%.
