ADDITIVE MANUFACTURING APPARATUS USING A SEMI-SOLID EXTRUSION OF WIRE
20180290194 · 2018-10-11 ·

An additive manufacturing apparatus to build a three-dimensional metal object using a semi-solid filament extrusion method is disclosed. A frame comprises a carriage capable of moving in Y-axis and Z-axis direction. The frame further comprises an extruder head, which is attached to a support section of the carriage is configured to move in X-axis direction to continuously print a filament in a layer by layer fashion using a thixo-extrusion process on a print bed in a pre-defined three-dimensional path. The filament is a treated metal alloy fed into the extruder head via a feeder mechanism and heated to a semi-solid state to allow the controlled flow of the slurry via a nozzle section to build the three-dimensional extruded object with the predetermined microstructure. The metal alloy is pre-processed using a heat treatment and a mechanical deformation technique to enhance the properties of the filament used in the semi-solid extrusion process.

COMPOSITE FILAMENTS HAVING THIN CLADDINGS, ARRAYS OF COMPOSITE FILAMENTS, FABRICATION AND APPLICATIONS THEREOF

A method of fabricating composite filaments is provided. An initial composite filament including a core and a cladding (such as a Pt-group metal) is cut into smaller pieces (or is first mechanically reduced and then cut into smaller pieces). The smaller pieces of the filaments are inserted into a metal matrix, and the entire structure is then further reduced mechanically in a series of reduction steps. The process can be repeated until the desired cross sectional dimension of the filaments is achieved. The matrix can then be chemically removed to isolate the final composite filaments with the cladding thickness down to the nanometer range. The process allows the organization and integration of filaments of different sizes, compositions, and functionalities into arrays suitable for various applications. Materials and components made from such composite filaments and arrays of composite filaments are also disclosed.

Method for Producing Polishing Bar Made of Valve Steel 53Cr21Mn9Ni4N

This invention provides a method for producing a polishing bar made of valve steel 53Cr21Mn9Ni4N. The process flow is as below: electric furnace smelting.fwdarw.outside-the-furnace refining.fwdarw.continuous casting.fwdarw.heating.fwdarw.high-speed wire rolling.fwdarw.heat treatment (off-line/online).fwdarw.straightening.fwdarw.polishing.fwdarw.inspection.fwdarw.storage. The production method of the invention adopts a casting method of continuous casting to overcome the poor high-temperature plasticity and the great deformation resistance of 53Cr21Mn9Ni4N which leads to a difficulty in continuous casting. The continuous casting is directly carried out on casting billets for rolling, which greatly reduces the material loss and energy consumption of this step, and improves the yield of the billets. The high-speed wire precision rolling technology is directly used on the continuous casting billets to improve the production efficiency, and greatly improve the size precision control of rolled and finished wire rods.
