In manufacturing process of rocket components, quenching and tempering process can be used to achieve suitable hardness, ultimate tensile strength and yield strength of raw material. The trial and error of quenching and tempering process to succeed suitable properties of raw material will waste of budget and time. In this study, numerical analysis of quenching and tempering process on AISI 4130 steel was investigated comparative to actual heat treatment process to evaluate the agreement between them.

Abstract:
In this work, an experimental study of wear evaluation in combination with a finite element analysis (FEA) was carried out for austempered ductile iron (ADI) used in gears. Two different ADI materials were used to produce gears which were tested in a FZG back-to-back test rig. The experimental results were compared to those of carburized AISI 8620 steel and induction hardened AISI 4140 steel gears. The wear resistance for pitting and spalling on the gears surfaces were measured using image analysis. Comparing the two types of ADI, the one with smaller nodules showed a higher pitting resistance

Abstract:
The microstructure and mechanical properties of AISI 4130 and austenitic stainless-steel overlay dissimilar weld joint using Shield Metal Arc Welding (SMAW) process were investigated. Two different filler alloys have been employed (ENiCrFe-3 and E309 MoL-17). A type II boundary was formed close to the fusion boundary at the AISI 4130 side, due to the diffusion of carbon from the carbon steel (CS) base metal towards the weld metal. On the other side, the joints strength and hardness profiles were almost independent of filler alloy, where the highest hardness value was recorded in the area betwe

Laser surface transformation hardening (LSTH) of AISI 4130 was investigated by a Nd:YAG pulsed laser. Laser focal height (LFH), pulse width (LPW), scanning speed (LSS), and power (LP) varied during the experiments. The microstructure of the treated zone was characterized by optical (OM) and field emission scanning electron microscopy (FESEM). Micro-hardness was measured in the width and depth directions. Results showed that the hardness and depth of hardened layer increased by decreasing the LSS and the laser focal position (LFP), and by increasing the LPW. The results were compared with those

Abstract AISI 8630 steel used in subsea applications is subject to hydrogen embrittlement from externally applied cathodic protection. In this work, susceptibility variation on three grades of 8630 steel of different yield strength (YS), 100 ksi, 110 ksi and 120 ksi, were evaluated in terms of fracture toughness. Two different testing methods, slow rising displacement and incremental step loading testing, were used to generate J-R curves and determine the fracture toughness. The tests were performed at 40°F in air and simulated sea water (3.5 wt.% NaCl) with applied CP of −1050 mV SCE. The nor

Abstract:
Abstract Nowadays welding is the most common way to connect metal parts and structures. One of the challenges connected to welding it that heat output from the welding alters the microstructure of the metal creating the heat affected zone (HAZ) near the weld. In steel welds HAZ is often harder and more brittle than the base material due to formation of martensite. This might cause hydrogen induced cracking and speed up the fatigue of the weld. To mitigate the martensite formation in the HAZ different heat treatments, like preheat, interpass and PWHT are often applied. However, for 4130 steel,

In subsea oil and gas systems, low-alloy steel (LAS) forgings need to be welded to leaner steels such as X and F-65. While the LAS needs to be post-weld heat treated (PWHT) to relieve stresses and temper the HAZ microstructure in order to avoid hydrogen cracking, the same heat cycle would, in general, result in the degradation of the properties of the leaner alloy. A buttering technique is, therefore, usually used so that the buttered LAS forging can be heat treated before the closure weld is carried out.
