Pressure Stress

The inverse magnetostrictive effect provides a chance to detect the stress by measuring some magnetic parameters. So it is important to learn the effect of stress on some magnetic parameters. A measuring system to measure magnetic permeability and magnetic loss and a device to load uniaxial tension and pressure stress were developed. The result shows that magnetic permeability and magnetic loss increase with uniaxial tension stress increase and decreases with uniaxial pressure stress increase. It is also concluded that the relative change of magnetic permeability and magnetic loss decrease with increase of the included angle between the directions of the stress and magnetic field. These results suggest that magnetic permeability and magnetic loss can be further used to evaluate the stress in low-carbon steel.

The Magnetic Field

The austenite steel after rolling was radiated by the alternating magnetism, and the effects that alternating magnetic on the austenite transition was studied. The result shows that the alternating magnetism promotes the austenitic grain growth of low carbon steel. If the magnetic field intensity is increased, it could provide better performance of raw materials to cold rolling processing.

Quench Hardening

In practice, welded low carbon steels do fail at the welded joints in use, thus leading to structural defects, material wastages, structural failure, and at times loss of lives, among others. This has been a great concern to practicing Engineers and Researchers. This study tends to proffer solution to this problem of concern through application of post welded thermal treatments. The welded samples were subjected to some post-weld thermal-treatment (TTP) operations such as normalizing, annealing and quench-hardening using different quenching media (Water, Palm oil, Quartz 5000 Total Engine oil, and Ground nut oil). The Tensile properties of the steel (such as tensile stress, tensile strain, and toughness) were determined before and after welding operations. At yield points, the thermal treatment processes adversely affected the strength of the welded steel. Meanwhile, normalizing and annealing processes enhanced the steel’s ductility and toughness, while quench-hardening process, irrespective of medium of quenching used reduced the steel toughness value. The toughness of the welded steel at the fracture point was also reduced through all the adopted thermal processes, except for normalizing process. The steel ultimate tensile stress and strain and its toughness values were equally reduced after TTP. Improvement of the properties of welded low carbon steel and the reduction of mechanical hazard were achieved through effective TTP. Thus, a better tensile property of welded low carbon steel was elicited by post-weld normalizing and annealing operations. Hence, butt-welded annealed and normalized low carbon steel specimens tend to be more resilient to failures at welded joints.

In this study, three welding methods are used. The purpose to investigation the effects of SMAW, SAW, and gas tungsten arc welding (GTAW) on the tensile stress of low carbon steel conforming to ASTM 283 c. 8mm thick plates are used as base material for butt welded joints. The tensile properties of the welded joints were evaluated and the results were compared by experts using the Taguchi method to design three levels of each parameter (current, voltage and displacement speed). From this research, it is found that compared to metal shielded arc welding and submerged arc welding, the pulling effect of the gas shielded welding joint of the tungsten electrode is the best. This is mainly due to the presence of The results of using analysis of variance (ANOVA) to estimate important parameters show that welding current and speed of the weld have a significant effect on tensile stress .the experimental results are in agreement with predicted results, and the maximum error is 3%..

The austenite steel was radiated by the intermediate frequency pulsating magnetism, and the effects that pulsating magnetic on the austenite transition was studied. The result shows that the pulsating magnetism promotes the austenitic grain growth of low carbon steel. If the magnetic field intensity is increased, it could provide better performance of raw materials to cold rolling processing.
