Isi ihe nke Tungsten Alloy

Tungsten Alloy bụ ụdị alloy ihe na mgbanwe metal tungsten (W) dị ka ike na-adọ na nickel (Ni), iron (Fe), ọla kọpa (Cu) na ndị ọzọ metal ọcha dị ka bonding na-adọ. Ọ nwere ezigbo thermodynamic, kemịkalụ na eletriki ma ejiri ya mee ihe na nchekwa mba, agha, ikuku, ụgbọ elu, ụgbọ ala, ahụike, ngwa elektrọn na mpaghara ndị ọzọ. A na-ewebata ihe ndị bụ isi nke tungsten alloys n'okpuru.

1. Nnukwu njupụta
Njupụta bụ uka kwa nkeji olu nke ihe na njirimara nke ihe. Ọ bụ naanị ihe jikọrọ ya na ụdị ihe na-enweghị ihe jikọrọ ya na oke na olu ya. Njupụta nke tungsten alloy bụ n'ozuzu 16.5 ~ 19.0g / cm3, nke bụ ihe karịrị ugboro abụọ njupụta nke ígwè. N'ozuzu, ka ọdịnaya nke tungsten dị elu ma ọ bụ na-ebelata ọdịnaya nke metal bonding, nke dị elu nke njupụta nke tungsten alloy; N'ụzọ megidere nke ahụ, njupụta nke alloy dị ala. Njupụta nke 90W7Ni3Fe bụ ihe dịka 17.1g/cm3, nke 93W4Ni3Fe bụ ihe dịka 17.60g/cm3, na nke 97W2Ni1Fe bụ ihe dịka 18.50g/cm3.

2. Ebe mgbaze dị elu
Ebe mgbaze na-ezo aka na okpomọkụ nke ihe na-agbanwe site na siri ike gaa na mmiri mmiri n'okpuru ụfọdụ nrụgide. Ebe mgbaze nke tungsten alloy dị oke elu, ihe dịka 3400 ℃. Nke a pụtara na ihe alloy nwere ezigbo nguzogide okpomọkụ na ọ dịghị mfe ịgbaze.

3. Isi ike dị elu
Isi ike na-ezo aka n'ikike nke ihe nwere ike iguzogide nrụrụ indentation nke ihe ndị ọzọ siri ike na-akpata, ma bụrụ otu n'ime ihe dị mkpa na-egosi nguzogide ihe onwunwe. Isi ike nke tungsten alloy bụ n'ozuzu 24 ~ 35HRC. N'ozuzu, ka ọdịnaya tungsten dị elu ma ọ bụ na-ebelata ọdịnaya metal njikọ, otú ahụ ka ike nke tungsten alloy na-esiwanye ike ma na-eme ka ọ dịkwuo mma; N'ụzọ megidere nke ahụ, obere ike nke alloy ahụ, ka njọ na-eguzogide iyi. Isi ike nke 90W7Ni3Fe bụ 24-28HRC, nke 93W4Ni3Fe bụ 26-30HRC, yana nke 97W2Ni1Fe bụ 28-36HRC.

4. Ezi ductility
Ductility na-ezo aka na ike nrụrụ plastik nke ihe tupu ịgbawa n'ihi nrụgide. Ọ bụ ikike nke ihe iji meghachi omume na nrụgide na nrụrụ na-adịgide adịgide. Ihe ndị dị ka akụrụngwa akụrụngwa na teknụzụ mmepụta na-emetụta ya. N'ozuzu, ka ọdịnaya tungsten dị elu ma ọ bụ na-ebelata ọdịnaya metal njikọ, na-ebelata elongation nke tungsten alloys; N'ụzọ megidere nke ahụ, elongation nke alloy na-abawanye. The elongation nke 90W7Ni3Fe bụ 18-29%, nke 93W4Ni3Fe bụ 16-24% na nke 97W2Ni1Fe bụ 6-13%.

5. Ike ike dị elu
Ike tensile bụ uru dị oke mkpa nke mgbanwe site na nrụrụ rọba edo edo gaa na nrụrụ plastik etinyebere na mpaghara, yana ikike ibu ihe kachasị n'okpuru ọnọdụ esemokwu kwụ ọtọ. Ọ metụtara ihe mejupụtara, akụrụngwa akụrụngwa na ihe ndị ọzọ. N'ozuzu, ike nkwụsị nke tungsten alloys na-abawanye site na mmụba nke ọdịnaya tungsten. Ike ike nke 90W7Ni3Fe bụ 900-1000MPa, na nke 95W3Ni2Fe bụ 20-1100MPa;

6. Ọmarịcha ọrụ nchekwa
Ịrụ ọrụ nchekwa na-ezo aka n'ikike nke ihe iji gbochie radieshon. Tungsten alloy nwere ọmarịcha ọrụ nchekwa n'ihi njupụta ya dị elu. Njupụta nke tungsten alloy bụ 60% dị elu karịa nke ndu (~ 11.34g / cm3).

Tụkwasị na nke ahụ, akwa tungsten dị elu bụ ndị na-adịghị egbu egbu, enyi na gburugburu ebe obibi, ndị na-adịghị na redio, ọnụ ọgụgụ mgbasawanye ọkụ dị ala na ezigbo conductivity.
