An Analysis of the Mechanical Behavior of AISI 4130

ultra-high strength steels, such as AISI 4340 and SAE 300M, to reduce weight and improve mechanical properties at the weld beads. AISI 4130 steel had also been considered, since it is applied in landing gears, small aircrafts engine cradles, and also in the general industry [1, 3 5]. Effects of Laser Hardening Process Parameters on Case fact, the Nd:YAG laser allows a small spot size, a higher energy density and a higher energy absorption rate of the part [13]. Another study explored the laser heat treatment applied to AISI 4340 steel using various frequen-cies and amplitudes of oscillation scanning with a fiber laser power varying from 2 kW to 3 kW.

Oct 25, 2020 · AISI 4340 steel [ 1 ], a heat treatable, low alloy steel, is widely used in structural applications due to its high ductility and fracture toughness in addition to having a high yield strength [ 2 ]. AISI 4340 steel has alloy contents of Cr, Mo, Ni, Mn, and Si for a total alloy content of less than 5%. Metallurgical and Mechanical Research on Dissimilar

  • AbstractIntroductionResearch MethodResults and DiscussionConclusionsDissimilar electron beam welding of 316L austenitic stainless steel and AISI 4340 low alloy high strength steel has been studied. Studies are focused on effect of beam current on weld geometry, optical and scanning electron microscopy, X-ray diffraction of the weld microstructures, and heat affected zone. The results showed that the increase of beam current led to increasing depths and widths of the welds. The optimum beam current was 2.8mA which shows full penetration with minimum width.

    AISI 4340 steel was selected for the current work, as an example for hard-to-machine materials. Physical properties were defined as function of temperature, and were obtained from [13]. The well-known Johnson Coo k (J C) plasticity model, Eq. 1, was used to model the workpiece material plastic behaviour, whe re Table 1 shows the AISI 4340 values. Relationship between fracture toughness and fracture In AISI 4340 steel, martensite forms in laths on quenching. The final decomposed microstructure (generally achieved by long term exposure to elevated temperatures) is a mixture of iron and iron carbide in the form of layers (pearlitic) or carbide spheres in a iron matrix (spherodized).92 In between these two extremes there may exist a multitude

    (e.g., 430, 434, 442 and 446). Many of the highly alloyed ferritic stainless steels are only available in sheet and tube forms and are usually welded by GTA without filler metal. 3.2 MARTENSITIC STAINLESS STEELS The martensitic stainless steels contain 11 to 18% Cr, up to 1.20% C and small amounts of Mn and Ni and, sometimes, Mo. These steels The determination of dynamic fracture toughness of AISI DYNAMIC crack propagation experiments have been performed using wedge loaded double cantilever beam specimens of an austenitized, quenched and tempered 4340 steel.

    AISI 434 stainless steel is a modification of Type 430, one of the most widely used of the"non-hardenable" ferritic stainless steels. The addition of molybdenum increases this alloy's corrosion resistance and its attack from many deicing chemicals. AISI 434 stainless steel also provides good heat and oxidation resistance up to 1500°F (816°C) as well as good mechanical properties.
