EP2737971A1 - Tailor welded blank, manufacturing method

Disclosed are a tailor welded blank and a manufacturing method thereof. The tailor welded blank is manufactured by connecting blank elements of different materials or thicknesses, thereby eliminating quality problems in a welded zone. A hot stamped component is manufactured by hot stamping the tailor welded blank formed by laser-welding blank elements made of coated steel plates having Impact of Vacancies on the Mechanical Properties of Dec 22, 2016 · Tailoring the Mechanical Properties of Earth-Abundant Transition Metal Borides via Bonding Optimization. Microstructures and mechanical properties of wear-resistant titanium oxide coatings deposited on Ti-6Al-4V alloy using laser cladding.

Influence of heat treatment on microstructures and

Jun 25, 2019 · Pores, which form easily during laser cladding, significantly deteriorate the mechanical properties of nickel-based alloys . Pore formation can be minimized and even eliminated by hot isostatic pressing (HIP), which closes pores at high temperatures and high hydrostatic pressures . Influences of depositing materials, processing parameters The effects of different cladding materials, processing parameters and heating regimes on the underlying microstructural features and mechanical properties of laser-cladded premium rails were investigated by using a hypereutectoid rail grade as a substrate, which is extensively used in heavy-haul rail systems.

Investigation of a novel functionally graded material for

In this study, the effects of cladding direction, preheating and post heat treatment on microstructural and mechanical properties of laser cladded rail repairs are presented. Laser cladding of a premium hypereutectoid rails grade with 410L stainless steel powder were conducted using a fibre laser gun with a Laser Cladding of Metals SpringerLinkLaser cladding is an additive manufacturing technology capable of producing coatings due to the surface fusion of metals. The selected powder is fed into a focused laser beam to be melted and deposited as coating. This allows to apply material in a selected way onto

Feature Papers represent the most advanced research with significant potential for high impact in the field. Feature Papers are submitted upon individual invitation or recommendation by the scientific editors and undergo peer review prior to publication. Microstructure and wear resistance property of AlFeCrNiMox Aug 09, 2019 · Limited by mechanical properties, the content of Mo in the alloys must be kept at a low level if used as structural material. However, if the alloys are used as coating materials for wear or corrosion resistance, the Mo content can be raised to even higher level because of the relatively low tensile strength requirements.

Microstructures and mechanical properties of wear

In this work, a freeze-dried TiO 2 nano-sized powder was used as the coating material and single tracks of TiO x coating were cladded on Ti-6Al-4V substrates using a diode laser. The microstructure, chemical composition, and mechanical properties of the coatings were characterized and Microstructures and tribological properties of laser Oct 15, 2016 · @article{osti_22689626, title = {Microstructures and tribological properties of laser cladded Ti-based metallic glass composite coatings}, author = {Lan, Xiaodong and Wu, Hong and Liu, Yong and Zhang, Weidong and Li, Ruidi and Chen, Shiqi and Zai, Xiongfei and Hu, Te}, abstractNote = {Metallic glass composite coatings Ti{sub 45}Cu{sub 41}Ni{sub 9}Zr{sub 5} and Ti{sub 45}Cu{sub

LASEr CLADDING 2013 WILEY-VCH Verlag GmbH & Co. KGaA, mechanical properties, wear and corrosion resistance. Detailed process development is required to tailor the coating properties for each application within the steel works (Fig. 3). The initial results from line trials were Phase Evolution and Properties of Al 2 CrFeNiMo x High Sep 09, 2015 · A series of Al2CrFeNiMo x (x = 0 to 2.0 at.%) high-entropy alloys coatings was synthesized on stainless steel by laser cladding. The effect of Mo content on the microstructures and mechanical properties of Al2CrFeNiMo x coatings was studied. The results show that the laser clad layer consists of the cladding zone, bonding zone, and heat-affected zone.

Real-time laser cladding control with variable spot size

Mar 06, 2014 · Laser cladding processing has been used in different industries to improve the surface properties or to reconstruct damaged pieces. In order to cover areas considerably larger than the diameter of the laser beam, successive partially overlapping tracks are deposited. Tailoring Microstructures and Mechanical Properties of Abstract:The microstructures and mechanical properties of AlCoCrFeNi0.3 high-entropy alloys (HEAs) are tailored through heat treatment. During heat treatment, the dendrite phase with a body-centered-cubic (bcc) structure transformed into the interdendrite phase with a bcc structure. Due to the element accumulation with higher hardness in the interdendrites and the increase of volume fraction of

Evaluation of the mechanical properties of laser cladded

Local material properties of the cladding layer, heat affected zone and substrate of laser cladded hypereutectoid steel rails were evaluated by uniaxial tensile tests on miniature specimens. Three laser cladding materials, i.e. 410 L, SS420 and Stellite 6, and two
