    Abstract: A method of sintering a metal injection-moulded, green aerofoil component. The method includes providing a setter having a stationary support arranged to support an aerofoil part of the component and a moveable platform arranged to support an end part of the component, the moveable platform being independently moveable relative to the stationary support. The method further includes locating the green component on the setter such that the aerofoil part and the end part are supported by respectively the stationary support and the moveable platform. The supported green component is then sintered, the moveable platform moving during the sintering relative to the stationary support to accommodate sintering-induced shrinkage of the component.

    Abstract translation: 一种烧结金属注射成型的绿色翼型零件的方法。 该方法包括提供具有固定支撑件的定位器，该固定支撑件布置成支撑部件的机翼部分以及布置成支撑部件的端部的可移动平台，所述可移动平台相对于固定支撑件可独立地移动。 该方法还包括将绿色部件定位在固定器上，使得机翼部分和端部分别由固定支撑件和可移动平台支撑。 然后将支撑的绿色部件烧结，可移动平台在烧结期间相对于固定支撑件运动，以适应组件的烧结引起的收缩。

    Abstract: A method of manufacturing a magnetically graded material, including depositing a steel filler material to a substrate, and applying a directed energy source to first and second regions of the filler material to thereby join the filler material to form a joined material. The energy source is directed to the first region while the first region is provided with an inert shield gas such that the material of the first regions includes a magnetic phase, and the energy source is directed to the second region while the second region is provided with a nitrogen containing shield gas to thereby impart an non-magnetic phase to the joined material.

    Abstract: An additive layer manufacturing method includes the steps of: a) laying down powder layer on powder bed, and b) focussing energy on an area of powder layer to fuse area of powder layer and thereby form a cross-section of the product; wherein steps a) and b) are repeated to form successive cross-sections of product, and wherein at least one of said steps b) involves focussing energy on an area of respective powder layer which is unsupported by a previously formed cross-section of product to thereby form a downwardly facing surface of product. Method is at least some of said successive steps b) involve focussing energy on a support area of respective powder layer, to fuse support area and thereby form successive cross-sections of a support pin within powder bed, support pin extending outwardly from downwardly facing surface of product when it is formed, so as to support downwardly facing surface.

    Abstract translation: 一种添加剂层制造方法，包括以下步骤：a）在粉末床上放置粉末层，b）将粉末层上的能量聚焦在粉末层的区域上，以熔化粉末层的面积，从而形成产品的横截面; 其中重复步骤a）和b）以形成产物的连续横截面，并且其中所述步骤b）中的至少一个包括将能量聚焦在相应粉末层的不被先前形成的产品横截面无支撑的区域上 从而形成产品向下的表面。 方法是所述连续步骤中的至少一些步骤b）包括将能量聚焦在相应粉末层的支撑区域上，以熔化支撑区域，从而形成粉末床内的支撑销的连续横截面，从向下的表面向外延伸的支撑销 的产品，以便支撑向下的表面。
