Abstract: This disclosure relates to swage type fasteners including a pin having a plurality of combination locking and breakneck grooves and a collar adapted to be swaged into the grooves with one of the grooves acting as a breakneck whereby the excess length of pin is severed generally at the end of the collar and also relates to a method of making the pin. The multigrip pin is formed generally into its final shape and then is subject to a heat treating process to provide a desirable microstructure whereby more consistent breaks at the selected groove occurs. In one form of the invention a desirable microstructure consists of predominantly pearlite colonies with a proeutectoid ferrite matrix interspersed at the boundaries of pearlite colonies.

Abstract: An article is hardened or tempered in a localized zone. Where the article is a thread-forming device the zone is that part of its thread that does the thread-forming in the workpiece. The hardness of the remainder of the body of the article is left unchanged. The localized hardening is carried out by a method that includes high frequency induction heating only of the zone followed by quenching of the zone whereby the hardened zone is a skin of predetermined depth. A machine for making articles in accordance with the method comprises means for delivering the articles in succession to an induction heating element, a mechanism for advancing the articles through the heating element for progressive heating of the surface of the article in the localized zone to a predetermined depth, a quenching manifold for applying a spray of quenching liquid to the heated article, and means for removing the heated articles from the heating element and conveying them to the quenching manifold.

Abstract: The present invention provides an improved structural assembly constructed of a plurality of structural members secured together. At least one of the plurality of structural members defines a first region characterized by comparatively high operational stress and a second region having a locally refined grain structure positioned such that the second region at least partially encompasses the first region to thereby enhance the strength, toughness and fatigue resistance of the at least one structural member in the first region. The present invention also provides a method for selectively improving the strength, toughness and fatigue resistance of a structural member in a region of high operational stress including the steps of casting the structural member in a pre-selected configuration. Regions of the structural member having comparatively high operational stress are identified. The structural member is secured to prevent movement. The region of the structural member having comparatively high operational stress is then mixed with a rotating friction stir welding probe to locally refine the grain structure of the structural member within the region of high operational stress to thereby improve the strength, toughness and fatigue resistance of the structural member in the region. The structural member can be secured to other structural members to form the frame of an aircraft. The improved structural assembly will have an increased operational life, as well as require less stock material with a corresponding decrease in the overall weight of the assembly.

Abstract: To produce threaded steel tension members, steel is used with a C-content of 0.50 to 0.80%, preferably 0.75%, a Si-content of 0.20 to 0.50%, preferably 0.25%, and a Mn content of 0.30 to 0.80%, preferably 0.60%. Exiting from the rolling heat at the outlet side of the finishing stand after hot rolling, the tension member or rod is subjected to surface quenching by a cooling medium, preferably water, so that the steel in a rim zone R.sub.1 is transformed immediately and completely into martensite, while the heat content remaining in the core zone K.sub.1 does not effect a tempering of the martensite rim zone during the subsequent cooling beyond the range of the intermediate stage. Steel tension members of this type have a high ductility and toughness at a high yield limit and high strength, they are corrosion-resistant to a great degree and have a wear resistant surface which makes them particularly suitable for threaded tension rods in which the threads are produced either by a cold forming operation or hot rolled ribs.
Abstract translation: 为了制造螺纹钢张力构件，使用C含量为0.20〜0.50％，优选为0.25％，Mn含量为0.30〜0.80％的C含量为0.50〜0.80％，优选为0.75％ 0.60％。 从热轧后的精轧机出口侧的轧制热量出发，通过冷却介质，优选水进行表面淬火，使得边缘区域R1中的钢被立即变形并完全变形 马氏体，而在随后的冷却过程中，在核心区域K1中残留的热量不会使马氏体边缘区域回火到超过中间阶段的范围。 这种类型的钢张力构件在高屈服极限和高强度下具有高延展性和韧性，它们在很大程度上具有耐腐蚀性，并且具有耐磨表面，使得它们特别适用于螺纹的螺纹拉杆 通过冷成型操作或热轧肋制造。
