The Application of High Pressure in Metal-deformation Processing
Author: F. W. Boulger
Publisher:
ISBN:
Category : Hydrostatic pressure
Languages : en
Pages : 82
Book Description
On October 3, 1963, a symposium was sponsored by the Bureau of Naval Weapons, Metalworking Processes and Equipment Program, on the application of high pressure in metal-deformation processing. Past research has shown that superimposed hydrostatic pressure can significantly increase the ductility at fracture of various materials. These observations have stimulated considerable interest in applying this hydrostatic-pressure effect to metal deformation processing, where it was anticipated that improved ductility and fabricability of brittle materials could be realized. Hydrostatic extrusion and hydrodynamic compressive forging were two such fabrication techniques discussed at the symposium, and preliminary results were found to be encouraging. Another fabrication process that will be investigated in the near future is sheet drawing, where the effect of superimposed pressure improves the ductility to fracture, it was noted that pressure cycling did not improve either the strength or ductility of steels containing various amounts of carbon. In addition to the mechanical-property effects, hydrostatic pressure has been found to affect measurably, numerous metallurgical properties of metals and alloys. (Author).

Metal Removal by Electrochemical Methods and Its Effects on Mechanical Properties of Metals
Author: John A. Gurklis
Publisher:
ISBN:
Category : Chemical milling
Languages : en
Pages : 52
Book Description
This report assembles and correlates information on the effects of electrochemical metal-removal (ECMR) processes on mechanical properties. Of special interest and concern are the effects of ECMR on fatigue strength. The report covers four electrochemical metal-removal processes: electrochemical machining (ECM), electrolytic grinding (EG), electrochemical milling, and electropolishing. General characteristics and applications of the four methods are presented and discussed; special emphasis is placed on ECM. The ECMR processes are especially useful in shaping high-strength and difficult-to-machine metals and alloys, as well as in shaping parts with unusual, complex, or fragile characteristics. (Author).

A Discussion of the Physical Metallurgy of the 18 Per Cent Nickel Maraging Steels
Author: Albert M. Hall
Publisher:
ISBN:
Category : Nickel
Languages : en
Pages : 34
Book Description
Various aspects of the physical metallurgy of the 18 % nickel maraging steels are discussed in this report in the light of the knowledge which has thus far been accumulated on these steels. The 18 % nickel type of maraging steel was singled out for discussion because of its especially attractive combination of strength and fracture toughness, the comparative simplicity with which it can be hardened, and the relative ease with which it can be formed and joined. The highnickel maraging steels are considered to be outstanding members of a loose-knit family of agehardenable or precipitation-hardenable martensitic steels. Some comparisons and analogies are drawn among various members of this family with particular reference to the 18% nickel steels. (Author).
