“…Further, the observed changes are practically independent of the exposure time. That is why in the work the time of the samples' exposure to a magnetic field was 30 minutes and always happened at room temperature (Zhan et al, 2016).…”

Under the influence of a constant magnetic processes in the future lead to destruction. Therefore, the authors investigated these processes in more detail. When studying the creep of the samples, a lever temperature) simultaneously with the application of the load (carried out by steps), an elongation of the sample was recorded with a micrometer (division price 10 load during the measurement, as well as smoo it is found that creeping increases under stable magnetic field; the main features appear at the first creep stage. Thus, preliminary exposure of samples in a constant magnetic field (with induc room temperature) leads to an increase in the absolute deformation of the aluminum alloy to 35%. The material deformation constants are also determined under " constant at the first stage of creep was found to be more than 6 times. Investigation of these processes will help to predict time dependence of creep strain and its rate as well as durability and plasticity at destruction.

The necessity and urgency of studying plastic deformation of metals is determined by both scientific significance of the problem and requirements of practice. So the objective of this work is investigation of aluminum alloy creep under action of static magnetic fields. This subject matter is of practical importance for engineering since the parts of engineering constructions are subject to various loads which may lead to their damage or even creep rupture. Based on the experiments performed by us, it is found that creeping increases under stable magnetic field; the main features appear at the first creep stage. Investigation of these processes will help to predict time dependence of creep strain and its rate as well as durability and plasticity at destruction.

“…2219 aluminum alloy is commonly used as rocket fuel tank material in aviation and space industries because of its high strength-to-weight ratio, high-temperature mechanical properties, and high corrosion resistance [16,17,18]. In recent years, TIG welding [19], MIG welding [20], electron beam welding [21], friction stir welding [22], and variable polarity plasma arc-welding [23], etc., were employed to weld 2219 aluminum alloy.…”

Abstract:In order to expand the application range of laser welding and improve weld quality, an extra pulse current was used to aid laser-welded 2219 aluminum alloy, and the effects of pulse current parameters on the weld microstructure and mechanical properties were investigated. The effect mechanisms of the pulse current interactions with the weld pool were evaluated. The results indicated that the coarse dendritic structure in the weld zone changed to a fine equiaxed structure using an extra pulse current, and the pulse parameters, including medium peak current, relatively high pulse frequency, and low pulse duty ratio benefited to improving the weld structure. The effect mechanisms of the pulse current were mainly ascribed to the magnetic pinch effect, thermal effect, and electromigration effect caused by the pulse current. The effect of the pulse parameters on the mechanical properties of welded joints were consistent with that of the weld microstructure. The tensile strength and elongation of the optimal pulse current-aided laser-welded joint increased by 16.4% and 105%, respectively, compared with autogenous laser welding.
