The application of the thermal analysis technology in metallic materials was introduced, for example, to measure phase transition critical temperature of the metallic materials and the Curie temperature of the magnetic material and the thermal effect of the phase transition. Keywords: thermal analysis technique; metallic materials; research; application 1、前言 热分析是在程序控制温度下测量物质的物理性质与温度之间对应关系的一项技术。主要包括如下三个方面的内容:一是物质要承受程序控温的作用,即以一定的速率等速升温或降温;二是要选择一观测的物理量P,该物理量可以是热学、磁学、力学、电学、声学和光学的等;三是测量物理量P随温度T的变化,往往不能直接给出两者之间的函数关系[1]。 热分析主要用于研究物理变化(晶型转变、熔融、升华和吸附等)和化学变化(脱水、分解、氧化和还原等)。热分析不仅提供热力学参数,而且还能给出有参考价值的动力学数据。因此,热分析在材料研究和选择上,在热力学和动力学的理论研究上都是很重要的分析手段[2]。 按照测量的物理性质,国际热分析协会(ICTA)将现有的热分析技术分类[3-4],具体见表1。热分析技术种类繁多,应用甚广,本文将介绍主要的热分析技术及其在金属材料研究中的主要应用。 表1 ICTA关于热分析技术的分类 测试性质方法名称英文全称缩名称质量热重法Thermogravimetry Analysis TGA 等压质量变化测定Isobaric Mass-change Determination 逸出气检测Evolved Gas Detection EGD 逸出气分析Evolved Gas Analysis EGA 放射热分析Emanation Thermal Analysis TEA

利用aspen-plus进行物性参数的估算

1 纯组分物性常数的估算 1.1、乙基2-乙氧基乙醇物性的输入 由于Aspen Plus 软件自带的物性数据库中很难查乙基2-乙氧基乙醇的物性参数, 使模拟分离、确定工艺条件的过程中遇到困难, 所以采用物性估算的功能对乙基2-乙氧基乙醇计算。 已知: 最简式:(C6H14O3) 分子式:(CH3-CH2-O-CH2-CH2-O-CH2-CH2-OH) 沸点:195℃ 1.2、具体模拟计算过程 乙基2-乙氧基乙醇为非库组分,其临界温度、临界压力、临界体积和临界压缩因子及理想状态的标准吉布斯自由能、标准吉生成热、蒸汽压、偏心因子等一些参数都很难查询到,根据的已知标准沸点TB,可以使用aspen plus软件的Estimation Input Pure Component(估计输入纯组分) 对纯组分物性的这些参数进行估计。 为估计纯组分物性参数,则需 1. 在 Data (数据)菜单中选择Properties(性质) 2. 在 Data Browser Menu(数据浏览菜单)左屏选择Estimation(估计)然后选Input(输入) 3. 在 Setup(设置)表中选择Estimation(估计)选项,Identifying Parameters to be Estimated(识别估计参数) 4. 单击 Pure Component(纯组分)页 5. 在 Pure Component 页中选择要用Parameter(参数)列表框估计的参数 6. 在 Component(组分)列表框中选择要估计所选物性的组分如果要为多组分估计

选择物性可单独选择附加组分或选择All(所有)估计所有组分的物性 7. 在每个组分的 Method(方法)列表框中选择要使用的估计方法可以规定一个以上的方法。 具体操作过程如下: 1、打开一个新的运行,点击Date/Setup 2、在Setup/Specifications-Global页上改变Run Type位property Estimation
