(PDF) Effect of Charpy Impact Test on Microstructure

The 4140 steel has been subjected to Charpy impact tests to investigate the microstructural properties of this steel, Chaouch et al. (2018); the effect of quenching and tempering heat treatments

Effect of microstructure and crystallographic texture on

Oct 01, 2016 · The Charpy impact test on rectangular sub-sized Charpy V-notch specimens parallel to the transverse direction of 55 mm × 10 mm × 7.5 mm (transverse × rolling × thickness direction), which was expected to be the lowest Charpy value, was conducted at room temperature by a WPM Leipzig pendulum impact tester of 500 J capacity (model:PSd 150 Effects of Cooling Rate during Quenching and Tempering but it has a detrimental e ect on low temperature toughness due to the formation of a hard secondary phase. Thus, tempering has been used to obtain a balance of strength and toughness by optimizing the toughness is di cult to obtain due to the non-uniform microstructure and the complicated e ects of and a Charpy impact test at 46 C. The

Evaluation of microstructural e ects on mechanical

The charpy impact test was carried out on the sub-size specimens with dimensions of 2:55 10 55 mm by a Zwick Roell testing apparatus. The fatigue specimens are shown in Figure 1, and evaluate the e ect of microstructure and grain size on the performance of steel coiled tubes. Ry= Ec y; (1) r= Ry 8:(2) The Effect of Tempering on the Microstructure and The E ect of Tempering on the Microstructure and Mechanical Properties of a Novel 0.4C Press-Hardening Steel Charpy-V impact toughness reduced section of the tensile test specimens were 10 mm 20 mm 120 mm. Charpy-V impact toughness testing was conducted at room temperature and at 40 C with three specimens for each

Effect of microstructure on the Charpy impact properties

Oct 01, 2019 · The Charpy V-notch samples had the dimensions of 10 × 10 × 55 mm. A 2 mm deep Charpy V-notch was cut through the thickness direction perpendicular to the deposition direction, and its schematic was shown in Fig. 3. Charpy impact tests were performed by a Charpy impact testing machine (JB-W300 J) at room temperature.
