Abstract

The major objective of this work is to study the hardness data at the domain of ferrite and Austenite phases. Nanoindentation and microhardness study has been conducted on austenite and ferrite present in the microstructure of hot rolled and heat treated duplex stainless steel (2205 DSS). Furthermore, Optical microscopy and field emission scanning electron microscope (FE-SEM) were used to identify the microstructural distribution and phases present. Austenite reveals higher nanohardness data value than ferrite, as oppose to ferrite average elastic modulus which is higher than that of austenite. Also, higher value of microhardness data was observed for austenite in comparison with the ferrite at different load application.

摘要

这项工作的主要目标是研究铁素体和奥氏体相区域的硬度数据。对热轧和热处理双相不锈钢（2205 DSS）微观结构中的奥氏体和铁素体进行了纳米压痕和显微硬度研究。此外，使用光学显微镜和场发射扫描电子显微镜（FE-SEM）来识别微观结构分布和存在的相。与铁素体平均弹性模量高于奥氏体相反，奥氏体显示出比铁素体更高的纳米硬度数据值。而且，在不同加载条件下，与铁素体相比，奥氏体的显微硬度数据值更高。
