“…Based on the data obtained by Kwok et al [22] and Rajput et al [23], this exponent is close to 3. However, when this exponent was determined on the basis of the results obtained by Baghel et al [27], it was close to 1, while Moore'a [28]-to 0.4. Nevertheless, the exponent can range from about 0.5 to over 3 in both types of erosion.…”

S235JR steel is used in many applications, but its resistance to the erosion processes has been poorly studied. To investigate this resistance, cavitation, and slurry erosion tests were conducted. These tests were carried out at different erosion intensities, i.e., different flow rates in the cavitation tunnel with a system of barricades and different rotational speeds in the slurry pot. The steel was tested as-received and after thermal treatment at 930 °C, which lowered the hardness of the steel. To better understand the degradation processes, in addition to mass loss measurements, surface roughness and hardness were measured. Along with increasing erosion intensity, the mass loss increased as well. However, the nature of the increase in mass loss, as well as the effect of steel hardness on this mass loss, was different for each of the erosion processes. In the cavitation erosion tests, the mass loss increased linearly with the increase in flow velocity, while in the slurry tests this relationship was polynomial, indicating a strong increase in mass losses with an increase in rotational speed. Cavitation erosion resulted in stronger and deeper strain hardening than slurry. Surface damage from cavitation erosion tests was mainly deep pits, voids, and cracks during the slurry tests, while flaking was the most significant damage.

“…Partial decreases in hardness were determined as a result of grain coarsening with increasing forging temperature. 9,10 In addition, although the grain boundary sizes in the microstructure of sample A are smaller than the grain boundary sizes of sample E, the hardness value is lower. This situation is occurred due to the removal of micro spaces and pores after forging.…”

“…After the forging process of sample A, the hardness of the samples increased with the removal of microvoids and pores in the microstructure (Figures 2 and 3). 10 The hardness, strength, ductility of steel materials, microstructure of the material and secondary processes (such as forging with heat treatment) applied to the material affect the workability. Micro-structured carbide, the fine grain size of residues and the presence of homogeneous grain colonies cause high fracture toughness and consequently increase in material strength.…”

In this study, AISI 1045 steel material was hot forged at 1100, 1150, 1200 and 1250°C temperatures. The microstructure and hardness of the test specimens after forging were investigated. The non-forged samples and forged samples were drilled with 6.8 mm diameter solid tungsten carbide drills. Drilling tests were performed in 80 and 120 m/min cutting speed combinations and 0.15, 0.20 and 0.3 mm/rev feed rate. After drilling operations progress forces, surface roughness, roundness deviation, the deviation from cylindricity and taper were investigated. It has been determined that AISI 1045 steel consists of ferrite + pearlitic microstructure and its hardness increases due to the removal of microvoids and pores by forging. It was also determined that the hardness of the samples decreased due to the coarsening in grain size depending on the cooling time with the increase of the forging temperature. It was observed that the feed force obtained during the drilling of the untreated sample in the perforation process was less than the values obtained during the drilling of the hot forging process samples. However, it was found that the measured surface roughness, roundness, cylindricity and conicity values of an untreated sample were more than the hot forging treated sample. It was observed that this situation was caused by the difficulties experienced in sawdust evacuation due to the longer hole length of the untreated sample. Feed rates, surface roughness, roundness, cylindricity and taper values decreased with increasing forging temperature. This situation arises from the decrease in the feed rate due to the decrease in the hardness of the samples, which occurs with the increase in the forging temperature. With the hot forging process applied to the untreated A sample, the hardness values of the forged samples increased between about 8.7 and 10%. The increase in feed force was between 11 and 20%. Surface roughness, Circularity, Cylindricity and Taper values decreased between 40 and 98% compared to the untreated A sample.

“…Two models were used for the study of the matter in the Eulerian frame of reference, and the results indicated a great reliance on flow characteristics and erosion patterns on geometric variations. Kumar et al [17] studied the erosion behavior of AISI 316 pipe bend with the implication of a swirl of different vane angles, and Baghel et al [18] studied the erosion wear on hot forged materials.…”
