Kita kabeh ngerti, diagram phase bisa diuji sacara eksperimental. Nanging, diagram tahap eksperimen mbutuhake sumber tenaga lan sumber daya sing akeh. Ing kondisi suhu dhuwur, tekanan dhuwur, lan gas nuju korosif, reaksi kasebut uga bakal nandhang kasulitan ing kontrol komposisi, pemilihan kontainer, lan pangukuran suhu sing dhuwur, lan tekad eksperimental tansah Limited, siji-sisi, ora bisa nggawe pangerten lengkap lan komprehensif saka diagram fase lan sifat termodinamika saka sistem. Gambar 1: Fe-C phase diagramKene, perhitungan diagram phase minangka solusi sing trep. Dheweke ng\u00e9tung keseimbangan fase sistem kanthi nggunakake prinsip termodinamika lan ngrancang diagram fase. Sawise pitungan diagram phase dienalake, mung data termodinamika saka sawetara wilayah kunci lan sawetara tahapan utama diagram phase saka sistem bisa diukur sacara eksperimental ngoptimalake param\u00e8ter modh\u00e8l energi b\u00e9bas Gibb, lan diagram fase kab\u00e8h bisa diekstraksi kanggo mbangun sistem kasebut. Database fase termodinamika fase lengkap. Akibat\u00e9, kasempatan saka studi diagram fase dikurangi, lan bisa uga ora bisa nyebabake kasus eksperimen. Ing istilah sing gampang, kalkulasi diagram phase bisa duwe 6 kaunggulan utawa makna sing penting (1) Bisa digunakake kanggo mbedakake fase aktual data diagram lan data termokimia kasebut dhewe lan konsistensi, supaya bisa nganakake evaluasi sing wajar saka asil eksperimen sing beda, lan kanggo menehi informasi informasi diagram fase sing akurat lan andhap; (2) Bagian metastable diagram diagram bisa diekstraksi lan diprediksi (3) Bisa extrapolate lan pr\u00e9dhiksi diagram multi-phase, ngitung keseimbangan multi-phase, lan nyedhiyakake referensi kanggo desain bahan sing bener lan teknologi pangolahan; (4) Kanthi ngitung kurva energi bebas Gibb, komponen transisi fase bebas difusi bisa diprediksi; (5) Bisa nyedhiyakake informasi penting kayata fase penggerak phase lan aktivitas sing dibutuhake kanggo panlit\u00e9n kinetika fase transisi; (6) Becike gampang kanggo nemokake macem-macem diagram phase karo variabel termodinamika minangka koordinat kanggo sinau lan ngontrol persiapan materi lan nggunakake proses ing kondisi sing beda. Dadi, ngapa bisa kita entuk diagram fase kanthi ngitung Tahap diagram kalkulus fase yaiku kanggo netepake model termodinamika saben phase miturut struktur kristal, susunan magnetik, lan transisi urutan kimia saben phase ing sistem target, lan mbangun Gibbs free expression energi saben phase saka model kasebut. Pungkasan, diagram phase diwiwiti kanthi kondisi keseimbangan. Antarane, param\u00e8ter sing ora ditemtokake ing saben modh\u00e8l termodinamika diduw\u00e8ni miturut imbangan fase lan data properti termodinamika sing dilapurak\u00e9 ing literatur lan dioptimalkan kanthi piranti lunak kalkulasi diagram phase. Adhedhasar param\u00e8ter termodinamika sing ditemokake ing sistem komponen cilik (umum sistem biner lan ternary), diagram fase lan informasi termodinamika saka sistem multikomponen bisa diduweni dening ekstrapolasi utawa nambahake sawetara parameter multivariate. Umum\u00e9, kita ngontrol suhu , tekanan, lan komposisi nalika proses materi. Mulane, kita milih Gibbs energi bebas minangka fungsi model ing perhitungan diagram fase. Kanggo sistem karo materi tartamtu nanging ijol-ijolan energi karo donya njaba (sistem tertutup), proses suhu lan tekanan konstan tansah ing arah Gibbs gratis pengurangan energi, lan total Gibbs energi free sistem iki paling kurang ing keseimbangn. Posisi kimia unsur-unsur konstituen ing fase sama. Yen kita ngerti kurva komposisi energi gratis ing kabeh temperatur, kita bisa ngitung diagram phase kanthi nemokake energi free minimal utawa sing setara karo bit kimia. Kanggo ngetung diagram phase, kita kudu ngerti bagian metastable kurva energi gratis , energi bebas saka konfigurasi metastable unsur murni lan titik transisi fase metastable. Optimasi diagram lan proses pitungan bisa mung dibagi dadi limang langkah: (1) Ngumpulake lan evaluasi data eksperimen. Asil penilaian kasebut yaiku kanggo ngadili akurasi data eksperimen adhedhasar metode eksperimen sing digunakake dening penulis, lan milih data eksperimen sing konsisten karo prinsip termodinamika lan relatif luwih akal. (2) Pemilihan model energi gratis. Miturut struktur fase, model sing cukup dipilih lan bisa diverifikasi kanthi ekstrapolasi sistem multivariate. (3) Nggunakake diagram phase diukur lan data termokimia kanggo ngoptimalake parameter sing ora ditemtokake ing ekspresi energi gratis Gibb; banjur nggunakake algoritma sing cocok lan program komputer sing cocog kanggo ngitung diagram phase ing komputer miturut kondisi keseimbangan fase. (4) Perbandingan lan analisis asil perhitungan lan data eksperimen. Yen ana prab\u00e9dan gedh\u00e9 ing antarane loro, nyetel param\u00e8ter sing bakal ditemtokake utawa bakal milih model termodinamika, banjur nindakake pitungan optimasi nganti asil perhitungan konsisten karo data diagram paling fase lan data termokimia sajrone rentang kesalahan eksperimen. (5) Sakwise optimisasi, kabeh diagram phase lan data termodinamika dihubungake karo model termodinamika dadi sakabehe konsisten, lan pungkasane disimpen ing parameter model kanggo mbentuk database termodinamika fase.
