The bioactive glass S520 was applied to an ultrafine-grained Ti-6Al-7Nb titanium alloy by a laser-directed energy deposition (LDED) process, in order to create a biocompatible material without potentially toxic vanadium for use in load bearing biomedical implants. The laser cladding process influenc...
Laser directed energy deposition (LDED) technology provides an opportunity to break through the size and geometry limitations of bulk metallic glasses (BMGs). However, the microcracks, induced by the huge thermal stress during the LDED process, seriously damage the mechanical properties of deposited ...
In the framework of Additive Manufacturing of metals, Directed Energy Deposition of steel powder over flat surfaces and edges has been investigated in this paper. The aims are the repair and overhaul of actual, worn-out, high price sensitive metal components. A full-factorial experimental plan has...
aessential 根本[translate] a These ties are the same. 这些领带是相同。[translate] aWhen the high energy of laser light is directed towards a small area, it can act as a high-speed drill. 当高能激光将一个小范围指向时,它可能作为一个高速钻子。[translate]...
The effect of non-isothermal treatment in oxygen-containing air, via heating rates of 10, 50, and 1000 °C/min until 1000 °C followed by furnace cooling to room temperature on oxides formed on directed laser energy additively fabricated IN718 was studied. Another set of samples heated ...
Directed energy deposition Multimaterial Copper Steel摘要 Additive manufacturing (AM) of a nickel-aluminum-bronze (NAB)/15-5 PH multimaterial by laser-powder directed energy deposition (LP-DED) accomplished a combination of excellent mechanical performance and high corrosion resistance. An NAB/15-5 PH...
Laser diode driver modules by Directed Energy come in a range of form factors, compliance voltages & pulse configurations allowing for multiple applications.
This technology is a force-multiplying capability, ready to integrate into future missions to transition it into the hands of the warfighter. As threats evolve, the LLD shows how directed energy can add one more layer of defense to protect our world. ...
Here, we present directed energy deposition (DED) of wrought-like Al 5xxx AlMg alloy by Laser Engineered Net Shaping (LENS®). A transition from an Al 5083 gas atomized powder feedstock to Al 5754 characteristics of the as-deposited material due to selective evaporation of Mg was observed....
Thin-walled metallic structures produced by the Directed Energy Deposition (DED) Additive Manufacturing (AM) process are prone to various fabrication defects, which hinder the wider applications of the technique in practice. In-situ inspection and monitoring methodologies are in high demand for improved...
