“…As a heat insulator, layer of aluminum oxide is used to mask the metal and then as a subsector a layer of graphite is used to cover that metal part. After this set metal part is heat treated at some temperature and this temperature is controlled by temperature controller [2].…”

“…The effect of heat treatment on the advanced high-strength steels was analysed by D. Bublikova et al [2]. Four experimental steels were taken in which Mn, Si, Cr, Mo & Ni are the main elements and that steel was further treated by Q&P process with consequently interrupted by quenching which resulted in martensite and retained austenite mixture structure.…”

“…Every type of heat treatment process has a different impact on the performance of the metal and alloys. Literature has shown that the high fraction retained austenite can be achieved from (Q&P) quenching and portioning processes [2]. Generally, the strength and hardness of the metal and alloys must be high to be utilized for various engineering applications.…”

Heat treatment can be simply defined as heating, holding, and cooling of materials. The current review paper presents the various types of heat treatment processes done on the different metals and alloys. A comparative analysis of the effect of heat treatment on hard-ness, yield strength, and microstructure, etc. of the various metals and alloys has been presented in this paper. The literature has shown that the heat treatment resulted in the development of new phases along with the improvement of microstructural and mechanical properties of various metals and alloys. The paper also represents the consequence of microwave heat treatment done on various substrates. The final part of the paper discusses the suggested future work that can be done.

“…The principles of vehicle structural integrity also require from AHSSs' an increased shock resistance and impact energy absorption [3]. Unlike the conventional high-strength steels (HSSs) with YS between 210 and 550 MPa and HTS between 270 and 700 MPa with the structure of "ferrite+pearlite", AHSSs possess a multiphase structure comprising different structural constituents other than pearlite (ferrite, martensite, bainite, retained austenite) in different combinations [4,5]. AHSSs are mostly consumed by the automotive industry although they are used for construction and other applications (rail transport, energy, infrastructure, shipbuilding, etc.)…”

The present article is aimed at studying the austenite transformation kinetics and tensile properties of constructional 0.2 wt%C-Si2Mn2CrMoVNb TRIP-assisted steel subjected to isothermal holding in the subcritical temperature range (350-650 °C with the step of 50 °C) after intercritical annealing at 770 °C. The study was fulfilled using optical microscopy (OLYMPUS GX-71), electron scanning microscopy (JEOL JSM-), dilatometric analysis, tensile testing, Vickers hardness measurements. The critical temperatures of the steel were found to be Ac1=750-760 °C and Ac3=930 °C. The results showed that austenite demonstrated increased stability to pearlite and bainite transformations with an incubation period of decades of seconds at any of the mentioned temperatures. The bainitizing treatment at 400 °C with holding of 300-600 s resulted in ferrite/bainite/retained austenite structure with precipitates of nanosized carbide (V,Nb)C providing an improved combination of mechanical properties as compared to direct quenching (YS=548-555 MPa, UTS=908-1000 MPa, total elongation=16-18 %, PSE index=14.6-18.0 GPa%, YS/UTS ratio=0.55-0.60). The contributions of different strengthening components were estimated in order to reveal the benefits of a multi-phase microstructure for constructional applications.

“…The samples were to be used for making optimized test specimens (Fig. 1) for thermomechanical treatment [8], [11], [13] in a thermomechanical simulator [7], [14]. The crucial part of such specimens is the central region (its width and length are 8.2 mm and 11 mm, respectively).…”

This study examines the options available in the unconventional process of abrasive waterjet cutting for making thermomechanical test samples. A series of experiments was carried out to identify the impact of individual cutting parameters on machined surface integrity. When using abrasive waterjet cutting, most engineering companies only adjust the jet pressure, the stand-off distance, the feed rate and, to a limited extent, the type and amount of abrasive in order to meet customer requirements and the requirements of the workpiece material. Special technologies entitled ProgressJet, MFC (Material Feed Control) and DRC (Dynamic Radius Correction) were experimentally tested in this study. Cutting time without traversing, the average cutting speed, abrasive consumption and the roughness and topography of specimen surfaces were measured. This study of integrity of surfaces produced by abrasive waterjet cutting (AWJ) contributes to evaluation of performance of individual cutting optimization technologies.
