T10 steel (920 ℃ solid boronizing 4h air cooling) metallographic diagram
Abstract
The martensitic transformation behavior of a type ofFriction Stir Welding C-Mn-Si-Cr-Mo-V-Ti-B hot rolled (HR) steel (grade T10 NW) was studied. The samples were heat treated at 920°C for 4 hours followed by air cooling. Microstructural characterization was performed by optical microsco......
Metallographic diagram of T12A
A microscopic examination is carried out on a specimen of the steel grade AISI 4340 which was heat treated in the lab. This steel grade is a low alloy, heat treatable steel grade containing chromium, nickel, molybdenum, and other alloy elements. A polishing of the specimen was completed in the lab......
