Inconel 718 is a high-strength nickel-based alloy specifically designed for extreme conditions. It is characterized by excellent corrosion resistance, high-temperature strength and good weldability. These properties make it indispensable in the aerospace industry, for example in turbines or rocket engines. Inconel 718 is also frequently used in the energy and chemical industries. Its reliability under extreme stresses contributes significantly to the safety and efficiency of modern technologies and makes the material an important component of innovative developments.
The aim of metallographic preparation of the Inconel 718 alloy is to produce an artefact-free and representative surface to examine the microstructure accurately. Through grinding, polishing and etching, microstructures such as grain boundaries, precipitates and phases are made visible. This enables an assessment of heat treatments, mechanical properties and potential defects. Careful preparation is crucial for making reliable conclusions about the material quality and the behaviors of the alloy under service conditions.
This month, you will learn everything about the complete metallographic preparation of an Inconel 718 alloy.
对钛合金进行金相分析在质量保证方面起着至关重要的作用。精确的制备、蚀刻和显微镜分析能够可靠地评估微观结构、晶粒尺寸以及可能存在的缺陷。特别重要的是识别可能影响机械性能的相变和结构不规则性。因此，金相学能够及早发现材料偏差，优化生产工艺，并确保与安全相关的部件具有长期的可靠性。
在本月的制备中，您将学习如何仅通过三个步骤就无假象地制备钛合金。

双相钢是一种具有奥氏体和铁素体两相微观结构的不锈钢。它常用于化工厂建设、石油和天然气工业、海洋工程以及储罐和管道建设。由于其高强度和出色的耐腐蚀性，特别是抗应力腐蚀开裂性能，它适用于苛刻的环境。热处理通常通过高温固溶退火，然后快速淬火来实现，以确保平衡的相结构并防止有害析出相的形成。对双相钢进行金相检验是为了分析其奥氏体和铁素体的两相微观结构特征。目的是评估相比例（理想情况下约为 50:50）、晶粒度以及任何可能存在的析出相或结构缺陷。取样后，将样品镶嵌、研磨和抛光以获得无划痕的表面。使用合适的腐蚀剂使相以高对比度显现出来。然后使用光学显微镜或扫描电子显微镜对样品进行检查。特别关注诸如σ相之类的金属间化合物相，因为这些相会对耐腐蚀性和韧性产生不利影响。因此，金相分析是质量保证的重要组成部分。 在本月的制备报告中，您将了解如何从双相钢中制备出无金相假象的样品。
