... and the graphite in part showed a granular formation, so that strength of the material was low. In a second crankcase with the same crack formation the structure in the thick-wailed part was better. But it also showed granular graphite in the ferritic matrix in the thin-walled part between the dendrites...

... Abstract During the operation of tractors with cantilevered body, the lateral wall of the hypoeutectic cast iron cylinder blocks cracked repeatedly. Three of the blocks were examined. The grain structure of the thick-walled part consisted of uniformly distributed graphite of medium flake size...

..., 2.49Si, 0.51Mn, 0.485P, and 0.112S. The iron was thus distinctly hypereutectic. The galling of the pump parts therefore was favored by an unsuitable structure caused by improper composition and fast cooling. Distortion by casting stresses may have been contributory or may have played the principal part...

... to the heat of welding ( Fig. 3 ). But the cracked pipe showed a ferrite-free mixed structure in the unaffected part consisting of pearlite and bainite phases ( Fig. 4 ). In the vicinity of the weld seam it had become coarse grained and was transformed into martensite ( Fig. 5 ). The cracking open...

... in part a purely martensitic structure ( Fig. 3 ) in the transition zone of the pipe material, that originally had a fine-grained structure of ferrite and pearlite ( Fig. 4 ). Hardness (HV 5) in this zone reached values from 376 to 401 kp/mm 2 when compared to 199 to 206 kp/mm 2 in the original pipe...

... and prioritize those considerations. Once those considerations are identified, the creative design process can commence, and the part or assembly can take on its geometry and structure. Once the design of the ideal concept is near completion, reflection or review is an important step, to verify that the intent...

... revealed that areas near the parting line exhibited a large grain structure not present in the forged stock. High-temperature scale was also found in the cracks. It was concluded that the cracks were caused by material being folded over the parting line. The folding occurred because of a mismatch...

... Abstract Distortion failure occurs when a structure or component is deformed so that it can no longer support the load it was intended to carry. Every structure has a load limit beyond which it is considered unsafe or unreliable. Estimation of load limits is an important aspect of design...

... under this pressure, an investigation was conducted to establish whether material or processing errors had occurred. Microscopic examination showed that a ferritic-pearlitic structure in select locations was very fine-grained. Other signs of fast cooling as compared to normally formed structure...
