Several different heat treatment processes were used to obtain various microstructures for investigation. Tensile tests and impact tests were conducted at elevated temperatures to determine the mechanical properties of the samples, while optical microscopy and scanning electron microscopy were used to analyze the microstructure of the materials.IntroductionAs a critical component in power generation, boilers play an essential role in providing safe and reliable power to various industries. The high-temperature environment and harsh working conditions of boilers demand that materials used in their construction exhibit excellent high-temperature mechanical properties and durability. As a result, high-strength low-alloy steels have become the preferred choice for boiler materials.12Cr1MoV is a type of low-alloy steel that has been widely used in the manufacture of high-pressure boilers due to its excellent high-temperature mechanical properties and good weldability. The material exhibits good oxidation resistance and has a high creep strength, making it an ideal candidate for use as the main material in high-pressure boilers.ObjectivesThe primary goal of this study is to investigate the high-temperature mechanical properties and microstructural characteristics of 12Cr1MoV boiler steel pipes. More specifically, we aim to achieve the following objectives:- Analyze the microstructure of 12Cr1MoV steel pipes using optical microscopy and scanning electron microscopy- Conduct tensile tests and impact tests on the steel samples...
