Abstract: Disclosed is an elongated metallic article having a curved section therein which has a first part formed on an outside part of the curved section, and a second part formed on an inside part of the curved section. The first part was initially deformed beyond a region of twin boundary deformation, but was thereafter returned to the region of twin boundary deformation. The second part was left deformed beyond the region of twin boundary deformation. When a compressive load is applied to the thus prepared article, and the first part and the second part are both compressed, the first part can deform more readily than the second part so that the article deforms into a more straight shape as its deformation progresses. Thus, the article may be made resistant to buckling in spite of the presence of the curved section.

Abstract translation: 公开了一种细长金属制品，其具有弯曲部分，其中具有形成在弯曲部分的外侧部分上的第一部分，以及形成在弯曲部分的内侧部分上的第二部分。 第一部分最初变形超过双边界变形区域，然后返回到双边界变形区域。 第二部分变形超出双边界变形区域。 当对这样制备的制品施加压缩载荷，并且第一部分和第二部分都被压缩时，第一部分可以比第二部分更容易变形，使得制品在其变形进行时变形为更直的形状。 因此，即使存在弯曲部分，制品也可以抗屈曲。

Abstract: A method for refining the grain size of alloys which undergo ferromagnetic to paramagnetic phase transformation and an alloy produced therefrom. By subjecting the alloy to a timed application of a strong magnetic field, the temperature of phase boundaries can be shifted enabling phase transformations at lower temperatures.

Abstract: The present invention is directed to an iron, aluminum, chromium, carbon alloy and a method of producing the same, wherein the alloy has good room temperature ductility, excellent high temperature oxidation resistance and ductility. The alloy includes about 10 to 70 at.% iron, about 10 to 45 at.% aluminum, about 1 to 70 at.% chromium and about 0.9 to 15 at.% carbon. The invention is also directed to a material comprising a body-centered-cubic solid solution of this alloy, and a method for strengthening this material by the precipitation of body-centered-cubic particles within the solid solution, wherein the particles have substantially the same lattice parameters as the underlying solid solution. The ease of processing and excellent mechanical properties exhibited by the alloy, especially at high temperatures, allows it to be used in high temperature structural applications, such as a turbocharger component.
