Abstract: A method for producing a particulate titanium alloy product can include preparing a composite particulate oxide mixture with TiO2 powder and at least one alloying element powder. The composite particulate oxide mixture can be co-reduced using a metallic reducing agent under a hydrogen atmosphere at a reduction temperature for a reduction time sufficient to produce a hydrogenated titanium alloy product. The hydrogenated titanium alloy product can then be heat treated under a hydrogen atmosphere and a heat treating temperature to reduce pore size and specific surface area to form a heat treated hydrogenated titanium product. The heat treated hydrogenated titanium product can be deoxygenated to reduce residual oxygen to less than 0.2 wt % to form a deoxygenated hydrogenated titanium product as a particulate. The deoxygenated hydrogenated titanium product can optionally be dehydrogenated to form the titanium alloy product as a particulate.

Abstract: Provided is a method for promoting densification of a metal body by utilizing metal expansion induced by hydrogen absorption. The hydrogen absorption expansion refers to a volume expansion effect produced by absorbing hydrogen on some metal blocks or metal powder in a hydrogen atmosphere under certain temperature conditions. Hydrogen is introduced into a rigid closed mold filled with a hydrogen absorption expansion material or filled with the hydrogen absorption expansion material and a material to be densified, and the mold and/or the material to be densified are/is densified by using the volume expansion effect of the hydrogen absorption expansion material. The present method may be used for eliminating residual pores from a metal material so as to improve the properties of the material.

Abstract: The technology relates controlling an autonomous vehicle through a multi-lane turn. In one example, data corresponding to a position of the autonomous vehicle in a lane of the multi-lane turn, a trajectory of the autonomous vehicle, and data corresponding to positions of objects in a vicinity of the autonomous vehicle may be received. A determination of whether the autonomous vehicle is positioned as a first vehicle in the lane or positioned behind another vehicle in the lane may be made based on a position of the autonomous vehicle in the lane relative to the positions of the objects. The trajectory of the autonomous vehicle through the lane may be adjusted based on whether the autonomous vehicle is positioned as a first vehicle in the lane or positioned behind another vehicle in the lane. The autonomous vehicle may be controlled based on the adjusted trajectory.

Abstract: Methods of removing oxygen from a metal are described. In one example, a method (100) can include forming a mixture (110) including a metal, a calcium de-oxygenation agent, and a salt. The mixture can be heated (120) at a de-oxygenation temperature for a period of time to reduce an oxygen content of the metal, thus forming a de-oxygenated metal. The de-oxygenation temperature can be above a melting point of the salt and below a melting point of the calcium de-oxygenation agent. The de-oxygenated metal can then be cooled (130). The de-oxygenated metal can then be leached with water and acid to remove by-products and obtain a product (140).

Abstract: An approach for identifying and managing tasks in an e-mail system. An e-mail task manager, receives an e-mail and creates n-grams based on e-mail data content and metadata content. The e-mail task manager identifies the e-mail as a task e-mail based on analyzing the n-grams to detect a task and a task owner. The e-mail task manager determines task details associated with the task e-mail based on the n-grams and determines a collection of recommended actions based on the task details. The e-mail task manager stores the collection of recommended actions and associated action states in a task history store. The e-mail task manager outputs the collection of recommended actions and the action states associated with the task e-mail based on the task owner and updates the collection of recommend actions and the associated action states based on interactions by the task owner.

Abstract: A method for producing a substantially spherical metal powder is described. A particulate source metal includes a primary particulate and has an average starting particle size. The particulate source metal is optionally ball milled and mixed with a binder in a solvent to form a slurry. The slurry is granulated to form substantially spherical granules, wherein each granule comprises an agglomeration of particulate source metal in the binder. The granules are debinded at a debinding temperature to remove the binder from the granules forming debinded granules. The debinded granules are at least partially sintered at a sintering temperature such that particles within each granule fuse together to form partially or fully sintered solid granules. The granules can then be optionally recovered to form a substantially spherical metal powder.
