Abstract: A method for detecting missing tooth in mining shovel, implemented using a processing device, includes receiving a pair of image frames from a camera disposed on a rope mine shovel configured to carry a mining load. A tooth line region corresponding to the pair of image frames is detected to generate a pair of tooth line regions based on a shovel template set. A difference image is determined based on the pair of image frames and the pair of tooth line regions. Further, a response map representative of possible tooth positions is determined based on the difference image using a tooth template matching technique. A tooth line is selected among a plurality of candidate tooth lines based on the response map. Further, a tooth condition is determined based on the tooth line and the difference image. The tooth condition is notified to an operator of the rope mine shovel.

Abstract: An additive manufacturing system includes a powder bed and at least one energy source configured to produce at least one energy beam for forming a build layer of a component from the powder bed. The additive manufacturing system further includes a computing device coupled to the at least one energy source. The computing device includes a processor and a memory device. The memory device includes instructions configured to cause the computing device to execute a manufacturing plan for manufacturing the component, receive component thermal data corresponding to at least a portion of the component during manufacturing of the component, and control the at least one energy beam in response to receiving the component thermal data to produce a predetermined microstructure within the portion of the component.

Abstract: A method for preparing an improved article including a nickel-based superalloy is presented. The method includes heat-treating a workpiece including a nickel-based superalloy at a temperature above the gamma-prime solvus temperature of the nickel-based superalloy and cooling the heat-treated workpiece with a cooling rate less than 50 degrees Fahrenheit/minute from the temperature above the gamma-prime solvus temperature of the nickel-based superalloy so as to obtain a cooled workpiece. The cooled workpiece includes a coprecipitate of a gamma-prime phase and a gamma-double-prime phase, wherein the gamma-prime phase of the coprecipitate has an average particle size less than 250 nanometers. An article having a minimum dimension greater than 6 inches is also presented. The article includes a material having a coprecipitate of a gamma-prime phase and a gamma-double-prime phase, wherein the gamma-prime phase of the coprecipitate has an average particle size less than 250 nanometers.

The cooled workpiece includes a gamma-prime precipitate phase having an average particle size less than 250 nanometers at a concentration of at least 10 percent by volume, and is substantially free of a gamma-double-prime phase. An article having a minimum dimension greater than 6 inches is also presented. The article includes a material that has a gamma-prime precipitate phase having an average particle size less than 250 nanometers, and is substantially free of a gamma-double-prime phase.
