METHOD OF FORMING ARTICLE, COATED POWDER AND ARTICLE
A method of forming an article includes producing a base powder including a plurality of base particles. Each base particle includes an external surface and a first material. The method further includes removing one or more oxides from the external surface of each base particle to form a cleaned powder including a plurality of cleaned particles. Each cleaned particle includes a cleaned external surface made of the first material. The method further includes coating the cleaned external surface of each cleaned particle with a second material having a greater oxidation resistance than the first material to form a coated powder including a plurality of coated particles. Each coated particle includes an external layer including the second material that fully covers the cleaned external surface made of the first material. The method further includes forming the article using the coated powder.
MACHINE LEARNING METHOD, MACHINE LEARNING DEVICE, MACHINE LEARNING PROGRAM, COMMUNICATION METHOD, AND CONTROL DEVICE
A machine learning method includes: calculating a reward for a result of decision of a cold isostatic pressing process condition based on an acquired state variable; updating, based on the reward, a function to decide at least one cold isostatic pressing process condition from the state variable; and deciding a cold isostatic pressing process condition which yields a highest reward, by repeating update of the function. The cold isostatic pressing process condition is at least one of a first parameter related to an object to be processed, a second parameter related to a preceding process of a cold isostatic pressing process, and a third parameter related to operating conditions of a cold isostatic pressing apparatus, and the at least one physical amount is related to at least one of sterilization and inactivation, shucking, improvement of taste and flavor, and improvement of texture and nourishment of the object to be processed.

Selective sinter-based fabrication of fully dense complexing shaped parts
The invention relates to a process for fabricating complex mechanical shapes from metal or ceramic, and in particular to fabricating complex mechanical shapes using a pressure-assisted sintering technique to address problems relating to variations in specimen thickness and tooling, or densification gradients, by 3-D printing of a sacrificial, self-destructing powder mold is created using e.g. alumina and swellable binders such as polysaccharides. The binder-free sintering powder that forms the manufactured item is injected into the mold, and high pressure is applied. The powder assembly can then be sintered by any pressure assisted technique to full densification and the self-destructing mold allows the release of the fully densified complex manufactured item.
