Metallographic diagram of granular bainite 12Cr2Ni4A
Introduction
Grain-oriented ferritic alloys, also known as Grain Boundary Enhancement Alloys or GBEA, have been around for decades, but until recently their importance has been largely overlooked. These alloys are known for their high strength and their ability to absorb impact, making them ideal......
Metallographic diagram of granular bainite 15CrMo
Introduction
Grain size is an important factor that affects the properties of a material. The microstructure of ferrous alloys with different grain sizes of 15CrMo has been studied by metallography. The grain size and pattern structure of the ferrous alloy can be measured with a metallographic mi......
