Kuv. Core Chemical Composition thiab Alloy Design Principles
1.1 Precise Chemical Composition Control (Loj Fraction, %)
| Lub ntsiab | Standard Control Range | Core Metallurgical Role | Kev cuam tshuam tshwj xeeb rau cov khoom |
|---|---|---|---|
| Alcov | Seem (≥98.5%) | Base hlau, tsim cov khoom matrix. | Xyuas kom yooj yim hluav taws xob / thermal conductivity thiab formability. |
| Fecov | 0.7 Tom mu 1.3cov | Core reinforcing keeb.Ua ntau yam sib txuas intermetallic nrog aluminium, Feem ntau zoo koob / pas nrig zoo li Al₃Fe theem. | 1. Dispersion Strengthening:Al₃Fe theem pin dislocations thiab grain ciam thaum lub sij hawm txias dov thiab annealing, ho nce zog thiab hardness. 2. Grain Refinement:Inhibits recrystallized grain loj hlob, ua rau ib tug uniform, zoo microstructure. 3. Txo Pinholes:Fe kho hydrogen hauv cov yaj, txo porosity nyob rau hauv lub ingot, yog li ntawd txo pinholes nyob rau hauv lub kawg ntawv ci. 4. Txhim kho Thermal Stability:High-melting-point Al₃Fe theem tiv thaiv coarsening thaum ua tom ntej (E.G., rov hais dua, ua kom tsis muaj menyuam), tswj cov khoom ruaj khov. |
| Thiabcov | ≤ 0.10cov | nruj me ntsis tswj impurity/trace alloy caij.cov | 1. Tswj Fe/Si Ratio:Cov ntsiab lus Si tsawg heev yog qhov tseem ceeb kom ua tiav qhov siab Fe / Si piv (feem ntau >7). Qhov no tsis txhob ua ntxhib, brittle α-Al(FeMn)Si los yog β-AlFeSi theem thaum lub sij hawm solidification. 2. Txhim kho kub ua haujlwm:Coarse Si-nplua nuj theem ua rau kub dov tawg. Tus qauv qis-Si tshem tawm qhov kev pheej hmoo no, ho txhim kho kub-rolling tawm los. 3. Txhim kho Ductility:Txo cov theem nkig, muab cov ntawv ci zoo ductility thiab tob-drawability txawm nyob rau ntawm ultra-nyias gauges. |
| Lwm yam impurities (Cu, Mn, Zn, lwm.) | Txhua qhov ≤0.05, Tus nqi ≤0.15 | Kev tswj nruj nruj rau purity. | Tiv thaiv kev tsim cov teeb meem hauv zos galvanic cell, kom ntseeg tau zoo heev corrosion kuj thiab ua raws li cov khoom noj / tshuaj tiv thaiv kev nyab xeeb. |
Qhov tseem ceeb ntawm Alloy Design: “Siab Fe, Low Si”.Qhov no tsis yog qhov yooj yim ntxiv / rho tawm ntawm cov ntsiab lus tab sis qhov sib npaug me me. Nws ua kom muaj zog ntxiv ntawm Fe (ntawm Al₃Fe theem) thaum txo qhov cuam tshuam tsis zoo ntawm Si (tshem tawm nkig Si-nplua nuj theem), tso cai 8079 kom ua tiav qhov zoo sib npaug ntawm lub zog, formability, pinhole kuj, thiab thermal stability.
II. Txheej txheem ntau lawm, Microstructure, thiab Kev Sib Raug Zoo
2.1 Core Ntau Lawm Txheej Txheem Flow
Melting & Casting (Precise Fe/Si ratio control) → Homogenization Annealing (Uniform composition) →
