Dɛn Nti na Solid Solution Treatment Ho Hia Ma Nickel-based Alloys?

Ɛkame ayɛ sɛ nickel afrafrade nyinaa hia solution treatment efisɛ solution treatment di dwuma titiriw wɔ alloys no adwumayɛ a ɛma ɛyɛ yiye no mu. Saa asɛm yi bɛkyerɛ nnyinasosɛm ne dwumadie a ɛwɔ ano aduru nipadua no mu afiri afã ahodoɔ mu.

 

Sɛ yɛhwɛ macroscopic a, solution nipadua no yɛ ɔkwan a wɔfa so de dade nneɛma afoforo (te sɛ dade, chromium, molybdenum, ne nea ɛkeka ho) gu nickel dade mu. Ɛte sɛ ɔkwan a wɔfa so de nkyene gu nsu mu no. Nanso, sɛnea ne din kyerɛ no, aduru nipadua no yɛ nneɛma a ɛyɛ den a wɔpete. Esiane ahoɔhare a atɔm a ɛyɛ den tu brɛoo nti, ano aduru a wɔde di dwuma wɔ ɔkwan a ɛkɔ akyiri so no hwehwɛ sɛ wɔma dade no yɛ hyew kodu ɔhyew pɔtee bi mu na ama atɔm no atumi akɔ baabiara a ɛnyɛ den, na wɔnam saayɛ so adu atirimpɔw a ɛne sɛ wɔbɛpete no ho.

 

Sɛ yɛhwɛ microscopic a, ano aduru nipadua no yɛ adeyɛ a dade nneɛma afoforo kɔ nikel ahwehwɛ no mu ma ɛyɛ anim-mfinimfini cubic nhyehyɛe foforo. Wɔfrɛ anim-mfinimfini cubic crystal wɔ solution akyi no austenite.

 

Wɔakyerɛ ano aduru nhyehyɛe no wɔ mfonini a edidi so yi mu:

Nneɛma titiriw nti a wɔyɛ solid solution treatment wɔ nickel-based alloys so no bi ne nneɛma a edidi so yi:

1. Dissolving ɔfã a ɛto so abien no na ama wɔanya homogenization
