Title: Tongue-and-groove type cold joint especially for aluminium alloy workpieces
Inventor: BRODAM MICHAEL
IPC: F16B17/00
Filed: 1997-06-04
Granted: 1999-01-07
Abstract: In a cold joint comprising a workpiece with a mushroom or sawtooth shaped projection (1) which fits into a matching recess of another workpiece and which abuts the recess bottom face with its front face, the novelty is that (a) at the to the projection (1) front face has a stud-like extension (2) of height (H) greater than the depth (T) of the recess (3); (b) the recess (3) has, at its edge zones (4a, b), two opposed flaps (5a, b) which are bent upwards towards the extension (2) so that their outsides act as slide faces (6a, b) for the abutment faces of the projection (1); and (c), in the joined state, the flaps fit into constrictions (7a, b) formed between the extension (2) and the projection abutment faces. Preferably, the joint is formed of an aluminium alloy containing 0.9-1.4% Mn, 0.6-1.2% Mg and/or 0.75-1.3% Si. Also claimed is a process for producing the above cold joint, in which the extension is pressed into the recess so that the bent flaps are deformed and upset and t he upsetting operation is continued until the extension has completely penetrated into the recess.

Abstract: FIELD: metallurgy. SUBSTANCE: method may be efficiently used when developing and improving technology of ingot formation under action of weak magnetic field on crystallizing melt. Method consists in that, when imposing constant magnetic field with induction B = (0.5-2.0)x10 -3  Tl on mathematical model derived from paramagnetic properties of crystalline nuclei in two-phase region of "structural diffusion" before crystallization front, nucleus receives magnetic moment influencing velocity of motion and corresponding to indicated induction value. Velocity of motion of nuclei, characterizing by its projection on vertical axis of ingot and linked with crystallization parameters, increases and is determined from equation: v =   + V cz  + V zos  where   is projection of average velocity of collective motion of "paramagnetic nuclei" in field possessing induction gradient; V cz  velocity of axial convective flow affected by field; V zos  loss of velocity caused by oscillation of magnetization vector in alternating field, equal to zero in constant magnetic field. Crystallization and segregation parameters: growth velocity of nuclei (V g ), overcooling (ΔT), and thickness of enriched layer (δ ef ) are determined from relationships: v = k 1 /V g , ΔT = k 2 / , δ ef  = D l /V       o   cr         , where k 1  and k 2  are coefficients depending on crystallization conditions; D l  coefficient of diffusion in liquid; V       o   er        velocity of hardening in zero field; k o = C s /C l  - equilibrium distribution coefficient; C s  and C l  concentration of impurity in solid and liquid phases; V n  and v projections of average velocity on axis of nuclei, respectively, enriched with impurity and solvent.
