摘要： Disclosed is a method for forming shapes and contours at least in a section of a metal part via a peening forming treatment, wherein in a closed loop the part can be formed fully automatically, including an overall evaluation of the treated (formed) part and loops for redefining the treatment process, if design requirements are not met after the forming. Before starting the treatment on the real part, a peening forming treatment profile (peening treatment strategy) is established via simulation on a digital twin of the part to be formed. Further disclosed is a working station for executing the method.

摘要： The present invention discloses a monocrystalline shape memory alloy consisting of: 11.5 % - 14.0 % Al by weight; 2.5 % - 5.5 % Ni by weight; 0.02 % - 0.58 % Be by weight, the Cu content and impurities being unavoidable. The alloy of the invention may have a martensitic transformation temperature between 400 K and 4.2 K, by adjusting the concentration of the elements thereof. The invention further discloses a method for preparing the alloy comprising the following steps: (i) Obtaining a first homogeneous alloy from a molten mixture of the Cu, Al, Ni and Be elements under an inert atmosphere; (ii) Placing an oriented monocrystalline seed, having a concentration similar to that of the monocrystalline shape memory alloy to be obtained, in a monocrystal growth equipment, by means of the vertical Bridgman or other growth method, and growing an oriented monocrystal by incorporating the first alloy obtained in step (i) into the equipment; (iii) Subjecting the monocrystal obtained in the preceding step, in a precipitated state, to a solubilisation treatment; (iv) Subjecting the monocrystal obtained in the preceding step to a tempering treatment, and (vi) subjecting the monocrystal obtained in the preceding step to an aging treatment until the monocrystalline shape memory alloy is obtained. The invention also discloses various uses of the alloy under temperature conditions from 400 K to 4.2 K.

摘要： The present disclosure provides assemblies (10), systems and methods for a single-step process for selective heat treatment of metals (16). More particularly, the present disclosure provides assemblies (10), systems and methods for a single-step process for selective heat treatment of metals (16) using multiple heating sources (12, 14). A hybrid modeling-test approach can be used in the design process to improve or optimize the process parameters to achieve location specific and improved/optimal microstructure and residual stress to enhance the part performance. It is also noted that performing the selective heat treatment in a single step can reduce the cycle time significantly. Moreover, large thermal gradients can be avoided in the part (16) as different volumes (22, 24) of the part (16) are heated to their desired temperature simultaneously.
