Evaluation of toughness in AISI 4340 alloy steel

(untempered) AISI 4340 steel has shown that compared to conventional austenitizing at 870~ increasing the austenitizing temperature to 1200~ can raise the plane strain fracture toughness (Kic) by a factor of two (without reduction in yield strength). However, concurrent with this improvement in Kic there is an INTERNATIONAL JOURNAL OF M SCIENCES AND Keywords Austempering Temperature, AISI 4340 Steel, Bainite and TAGUCHI I. INTRODUCTION ISI 4340 is a medium carbon steel with a carbon content ranging from 0.38 to 0.43 % Carbon and usually referred as nickel - chromium molybdenum high tensile steel. AISI 4340 are used widely in aircraft, particularly in critical

Laser Surface Treatment of SAE 4340 and 300M Steels

The 300M steel has emerged from the high strength SAE 4340 steel, which had been developed in order to obtain increased toughness and weldability in applications requiring better mechanical properties; some minor changes in the alloy elements were introduced:addition of vanadium, and raise in the silicon content. The laser surface hardening is a process in which the steel surface is heated Relationship between Fracture Toughness and Fracture 260 Relationship between Fracture Toughness and Fracture Surface Fractal Dimension in AISI 4340 Steel . phy. 3.
