摘要

金屬製品為能達到應用時所需的機械性質，必須安排進行熱處理以調整其硬度、強度、金相組織等性質。近年來因模擬分析技術之進步，已可應用開放源或套裝軟體進行熱處理製程之模擬分析。搭配材料特性計算軟體，可針對不同材料成份，預估該配方材料在不同熱處理製程（如淬火、回火、滲碳／氮、表面硬化等）下，製品各處可達之硬度及金相組織。本研究主要探討不同軟體目前可進行之熱處理模擬分析能力，以及透過測試案例呈現在不同冷卻條件下，軟體對金屬材料熱處理後硬度或金相組織之預測能力。

In order to achieve the required mechanical properties, heat treatment processes are commonly introduced to metallic production to adjust hardness, strength and metallurgy. Recently, open-source analysis tools and packaged simulation software could be used to perform heat treatment simulation. Furthermore, the influence of alloy compound on the hardness and phase fractions through different heat treatment processes such as quenching, tempering, carburization or nitriding, and surface hardening can be predicted. In this study, the simulation capability of different software is evaluated, and demo cases are presented to illustrate the prediction capability of hardness and phase fractions under different cooling conditions.
