The objective of this research work is to obtain the hot ductility behavior, and structural, microstructural mechanical characteristics one latest generation AHSS steels, a complex phase (CP) steel microalloyed with boron (0.006 wt.%), processed by cold rolling operations heat-treated using two different quenching partitioning (Q&P) treatments, one-step (quenching 420 °C) other two-step °C reheated 600 °C). results show that has marked effect on solidification process CP steel, refining...
A restorative process, where the nonmetallic fraction from e-waste printed circuit boards is reused as a raw material for conformation of new polymer matrix composite with increased properties favoring its industrial applications, proposed zero residues approach. Low density polyethylene pellets and particles were mixed, due to generation static electricity during mixing became attached pellets; blended was fed into screw extruder, producing filaments composite. Mechanical content increased,...
This research work reports the effect of boron micro-additions (180 and 470 ppm) on solidification structure, magnetic properties hot ductility behavior an advanced low-carbon highly alloyed twinning-induced plasticity (TWIP) steel. For this purpose, three experimental TWIP steels were fabricated by melting commercial raw materials casting into metallic molds. Solidification structure was characterized means optical scanning electron microscopy techniques, a statistical study carried out to...
In the present work, a Cr+Mo+Si low-alloyed low-carbon steel was fabricated at laboratory scale and processed to produce multiphase advanced high-strength steels (AHSS), under thermal cycles similar those used in continuous annealing galvanizing process. Cold-rolled samples with microstructure constituted of pearlite, bainite, martensite matrix ferrite, were subjected an intercritical (817.5 °C, 15 s) further isothermal bainitic treatment (IBT) investigate effects time (30 s, 60 120...
Abstract: Friction Stir Welding (FSW) is a solid-state joining process that uses non-consumable tool to join two facing workpieces without melting the workpiece material. FSW predominantly used for welding lightweight materials such as aluminum and magnesium alloys. In present investigation, AA6061-T6 AZ31B-H24 alloys were joined by using following parameters: rotational speed of 400, 800, 1200 1600 rpm, 30 60 mm/min tilt angle 1° 3°. some cases, offset 1 mm was into Mg-based alloy....
The present work presents a theoretical and experimental study regarding the microstructure, phase transformations mechanical properties of advanced high-strength steels (AHSS) third generation produced by thermal cycles similar than those used in continuous annealing galvanizing (CAG) process. evolution microstructure were discussed from behavior intercritical cooling transformation diagrams calculated with software JMatPro, further characterization steel scanning electron microscopy,...
Aluminum-based nanocomposites have been produced by mechanical milling, introducing silver nanoparticles within the matrix of a 7075 aluminum alloy using high energy ball mill. The milled products were compacted uniaxial load and pressure-less sintered under argon atmosphere, finally hot extruded. Silver are well dispersed into powder particles as in extruded material. Transmission electron microscopy (TEM) analyses used to corroborate understand hypothesis that second-phase finely...
Recent works about the development of carbide-free bainitic (CFB) steels use chemical compositions that require too long isothermal treatments for transformation, making it difficult their manufacture under industrial continuous annealing processes. The present work reports an approach designing CFB based on a computer simulation phase transformations as function chemistry. effect chemistry and treatment time microstructure mechanical properties are also investigated. Results show third...
