    Abstract: A technique for optimizing metal extrusion process parameters includes receiving values representing properties of an extrusion press machine, and calculating an estimated surface exit temperature of a metal work product resulting from an extrusion of a metal billet using the extrusion press machine based on the machine property values, an initial temperature of the metal billet prior to the extrusion, an extrusion force applied to the metal billet during the extrusion, and an extrusion speed of the metal work product. The estimated surface exit temperature of the metal work product is compared with a target hot shortness exit temperature of the metal work product. The initial temperature of the metal billet, the extrusion speed, and the extrusion force are changed based on the comparison until the estimated surface exit temperature equals the target hot shortness exit temperature.

    Abstract: Systems and methods for quenching an extrudate using an atomized spray of liquid are described. A system includes a billet die at a proximal end configured to accept a billet and form an extrudate, a quench chamber located adjacent to the billet die for receiving the extrudate and comprising at least one pulsed width modulation (PWM) atomizing spray nozzle and a control module in communication with the at least one PWM atomizing spray nozzle and configured to independently control a liquid pressure, a gas pressure, a spray frequency, a duty cycle and flow rate of each at least one PWM atomizing spray nozzle.

    Abstract: 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.
