Effect of Heat Treatment on Microstructure and

1 day ago · crostructure of the SLM processed GTD222. The microstructure and mechanical proper-ties of the as-built and heat-treated (HTed) GTD222 were investigated. The evolution of the microstructure and mechanical properties were discussed. This work can aid in opti-mizing the heat treatment process of the SLM processed GTD222. 2. Experimental

Effect of Powder Size on Microstructure and Mechanical

  • AbstractIntroductionExperimental ProceduresResults and DiscussionConclusionsThis paper studied the effects of powder size on densification, microstructure, and mechanical properties of the hot isostatic-pressed 2A12 aluminum alloy powder compact. The results show that the near-fully dense powder compact can be successfully achieved and the smaller the powder is, the higher the relative density is. In addition, as the powder size decreases, the precipitated phases in the powder compact change from continuously point-like distribution at the junctions among powder particles to thEffect of Cooling Rate on the Microstructure and May 02, 2016 · A variety of microstructures in medium carbon steels can be obtained depending on the forging parameters utilized and the post-forging cooling rate [4-7]. The present investigation is aimed to study the effect of cooling rate after controlled hot forging on the microstructure and mechanical properties of medium carbon steel 35C8 (AISI 1035). Effect of quenching temperature on the microstructure and Oct 01, 2019 · A low carbon steel microalloyed with Nb-V subjected to hot stamping process, then quenching to different temperatures (30 °C, 230 °C, 300 °C) followed by air cooling to room temperature was investigated. The method in this article was significantly simplified compared with the conventional quenching & tempering (QT) process. The results shown that the best comprehensive mechanical

    Microstructure and Mechanical Properties of Aged and Hot

    This study focused on the effects of ageing for various time at 175 °C before hot rolling on microstructure and mechanical properties of AZ80 magnesium alloys. The amount of -Mg17Al12 increased in line with ageing time and during the rolling process could facilitate the fine grains and sub-grains, which resulted in an inhomogeneous or bimodal microstructure, and weakening basal-type Microstructure and Mechanical Properties of Fe-18Mn-18Cr May 01, 2017 · Asymmetric hot rolling (ASHR) with a mismatch speed ratio of 1.15 in a single pass was applied to Fe-18Mn-18Cr-0.5N steel and was compared with symmetric hot rolling (SHR). The results indicated that a through-thickness microstructure gradient was formed in the plate due to the shear strain (0.36) introduced by ASHR. A fine-grained layer with the average size of 3 m was achieved at

    • AbstractIntroductionMaterials and MethodsResults and DiscussionConclusionsData AvailabilityConflicts of InterestAcknowledgments(1)The microstructure of the hot-rolled specimen becomes more and more homogenous with the increase of rolling temperature.(2)The homogenous hot-rolled microstructure is favorable for the subsequent cold rolling, which brings about the improved mechanical properties.(3)The specimen under the rolling temperature of 300°C possesses the highest tensile strength and hardness, 238MPa and 67.7 HV, respectively. The specimen under the temperature of 200°C possesses the highest elongation of 2Microstructural evolution and mechanical properties of Jun 03, 2021 · Open forging or hot pressing process is used to break the cast microstructure of ingot to improve the homogeneity and mechanical properties of die steels. Modeling of Microstructure and Mechanical Properties of An integral mathematical physically based model is developed for prediction of the microstructure and mechanical properties of steels processed in accordance with a given hot deformation and accelerated cooling regimes. The model predicts austenite microstructure evolution under hot deformation, as well as its transformation during subsequent cooling with account of formation of ferrite
